Our laboratory studies the interface between the skeletal and immune systems, a newly emerging area of research called “osteoimmunology”. Haematopoietic stem cells in the bone marrow give rise to both T cells which are important in inflammation and osteoclasts that regulate bone resorption. Differentiation and activation of osteoclasts from their precursors is tightly regulated by cytokines and growth factors such as receptor activator of nuclear factor kappa beta (RANKL), tumor necrosis factor (TNF) and various interleukins. Receptor engagement of these molecules results in signaling cascades and transcriptional changes that give rise to medical conditions such as rheumatoid arthritis, osteoporosis and osteopetrosis. Using in vivo gene transfer of immune cytokines IL-23 and IL-17, we have established new arthritis animal models that highlight the importance of these immune cytokines in arthritis initiation and bone homeostasis. Using in vitro assays, we continue our attempts to define the cellular and molecular mechanisms that take place in this fascinating interplay of the immune and skeletal systems.

Keith Baar, Assistant Professor

CBS: Neuro, Physio & Behavior

Cranial (or anterior) cruciate ligament (CCL) rupture is one of the most common orthopedic conditions in dogs. CCL rupture results in instability within the stifle that initiates a downward spiral of synovitis, articular cartilage degeneration, and eventually osteoarthritis. Currently, intracapsular techniques replace the ruptured CCL with an autologous tissue or synthetic graft. However, these grafts aren't strong enough and so the repair is usually augmented with some form of extracapsular reconstruction. We have developed a viable alternative that should be strong enough on its own to return joint stability. Our unique method uses stem cells to engineer a ligament in vitro. Our current research is finalizing the optimal growth factor cocktail and mechanical intervention before beginning our implantation trails.

Danika Bannasch

Canine and Equine Genetics

Department of Population Health and Reproduction

Our current and future research plans are directed towards elucidating the molecular basis of inherited diseases in companion animals. We are interested in developing tests to help breeders eliminate inherited diseases in dogs and horses. A large number of the diseases seen in veterinary practice that affect purebred animals have a heritable basis.

Characterizing inherited disease in dogs has the added benefit of providing an animal model for human diseases. Presently we have projects in both horses and dogs.  We are working on the molecular basis of Hoof wall separation syndrome and susceptibility to pneumonia in horses.  In dogs we are working on the molecular basis of Addison’s disease, cleft palate, spinal disraphism, Hypertrophic osteodystrophy and myopia in dogs.

Nicole Baumgarth

Center for Comparative Medicine; Immunity to infectious diseases

Dr. Baumgarth is a veterinarian and research immunologist with broad interests in infectious disease immunology. An underlying theme of all research studies in her laboratory is the use of mouse models to dissect the complexity of host-pathogen interactions. For that she has developed new technologies that allow a precise assessment and analysis of in vivo immune events. A major focus of her research involves studies on the regulation of early antiviral B cell immune responses to influenza virus. Ongoing work is directed towards identifying mechanisms by which infection-induced innate cytokines regulate the earliest events that trigger antiviral B cells responses. Members of her lab are working on the concept that innate cytokines regulate the thresholds by which lymphocytes are activated to participate in immune responses in order to avoid the negative consequences of a potentially overshooting immune response (autoimmunity). She is also involved in studies to delineate the causes for the lack of protective immunity to the Lyme disease pathogen Borrelia burgdorferi. Using a mouse model established by her collaborator, Dr. Barthold, they are following their earlier observations that B. burgdorferi subverts the B cell response to this pathogen, with the long-term goal to find targets for therapeutic intervention that could bolster the immune response of an infected individual to clear this bacterial infection.

Andreas J. Baumler

SOM: Medical Microbiology and Immunology

I am a microbiologist interested in Salmonella pathogenesis and host response. Our group has pioneered the use of a calf model to study Salmonella gastroenteritis and a rhesus macaque model to study co-infections with non-typhoidal Salmonella and HIV. In addition, we use the advantages of the mouse model to study host and bacterial factors involved in orchestrating intestinal inflammation. On the host side, we are interested in pattern recognition by the innate immune system (TLRs, NLRs and complement), pathways that amplify responses in tissue (the IL-23/IL-17 axis and the IL-18/IFNg axis) and effector responses induced in the intestinal epithelium (defensins, lipocalin-2, calprotectin, iNOS etc.). On the bacterial end, we study mechanisms that enable typhoidal Salmonella to evade innate immune recognition and mechanisms that enable non-typhoidal Salmonella to take advantage of the host inflammatory response to out-compete the microbiota in the gut.

Charles L. Bevins MD, PhD

Department of Microbiology and Immunology, School of Medicine

Our laboratory is interested in innate immunity of mucosal tissues, and we are focused on key effector molecules of host defense: antimicrobial peptides. Antimicrobial peptides are endogenous antibiotics, isolated from diverse species throughout the plant and animal kingdoms. They represent an evolutionary ancient mechanism of host defense. These peptides typically have a broad-spectrum of antimicrobial activity that includes bacteria, fungi and certain viruses.  Defensins are the major class of antimicrobial peptides in humans and other mammals.  Investigations from our laboratory have discovered that certain defensins are expressed in abundance by epithelial cells at wet mucosal surface.  Our studies support a model - antimicrobial peptide constitutes part of an active, early host defense response of challenged epithelial cells.  The long-range goal of our research is to understand the specific role that these epithelial antimicrobial peptides play in mucosal innate immunity, including maintaining homeostasis at baseline and responding to challenge by pathogenic microbes.  Our current collaborative studies include: (i) characterizing the primary structure and biological activity of the tissue forms defensins, (ii) defining the key regulatory steps for the expression of these molecules, (iii) exploring potential mechanisms of therapeutic modulation of these systems. The investigations include biochemical and molecular biological approaches and analysis of transgenic and other animal models.

Xinbin Chen, BVM, PhD

VM: Veterinary Oncology, Surgical and Radiological Sciences; Med: Internal Medicine

The p53 family proteins are transcription factors and consist of p53, p63, and p73. Each member regulates a diverse array of both common and unique target genes. These target genes mediate various activities for the p53 family proteins, including the cell cycle control, apoptosis, differentiation, senescence, DNA repair, normal development and tumor suppression. p53 is a tumor suppressor and found to be mutated or inactivated in greater than 60% of all human cancers. Mutant p53 is not only defective in tumor suppression but also promotes tumor formation. However, p63 and p73 appear to be necessary for the development of various tissues and immune response. To address these diverse activities for the p53 family proteins, we focus on the following areas of research: (1) to identify both common and unique target genes for each p53 family member and their functions in tumor suppression and development; (2) to determine the mechanism by which the p53 family proteins differentially regulate gene expression; (3) to determine the mechanism by which mutant p53 obtains a gain of function in promoting tumor formation; and (4) to determine the mechanism by which the expression and activity for each p53 family protein is regulated.

Potential Projects for STAR Students:

  • The p53 pathway, including p53, p63, p73, Mdm2 and MdmX, in dog osteosarcoma, sarcomas, histocytic sarcomas, and melanoma

  • The p53 pathway in cat sarcomas and other cat tumors

Dr. Christensen is a board-certified theriogenologist whose clinical work focuses on equine and canine reproduction. Dr. Christensen's research interests focus on endangered species reproduction. He has used domestic species as models for their endangered counterparts, such as using dogs as models for the Mexican gray wolf and horses and donkeys as models for Somali Wild Ass or Przewalski horses. Current research that may involve students includes use of the domestic stallion as a model for wild equids. We are testing the effects of a long-acting sedative, fluphenazine, on reproductive parameters in stallions. Fluphenazine is commonly used in zoo animals during introductions, during stressful events, or to make them a little more tractable over a short period of time. It is not known if the drug affects fertility. We want to evaluate its effects on testosterone concentrations, sperm parameters, and reproductive behaviors. Students would be involved with assessing reproductive behaviors, collecting semen and blood, and performing semenalysis.


Blaine Christiansen, PhD

Musculoskeletal adaptation, post-traumatic osteoarthritis, bone, biomechanics

UCDMC Department of Orthopaedic Surgery

Dr. Christiansen is a faculty member in the Department of Orthopaedic Surgery and the Biomedical Engineering Graduate Group. His research investigates the adaptation of musculoskeletal tissues, particularly bone and articular cartilage, to the mechanical environment, injury, aging, or disease using small animal models. The musculoskeletal system has an innate ability to repair and optimize itself based on the mechanical demands placed on it. By studying this adaptation, we are able to uncover the underlying mechanisms that contribute to diseases such as osteoporosis and osteoarthritis. Musculoskeletal adaptation is quantified in these models using advanced imaging techniques, histology, and mechanical testing. Current projects in the Christiansen lab include investigation of biomechanical and biological mechanisms contributing to the development of post-traumatic osteoarthritis, investigation of systemic bone loss following bone fracture or other musculoskeletal injury, and determining the effect of peripheral sensory nerve function on bone metabolism and bone adaptation to the mechanical environment.

Patricia A. Conrad DVM, PhD

VM: Pathology, Microbiology & Immunology

Dr. Conrad is a veterinary research parasitologist whose research focuses on protozoal parasites of animals (domestic and free-ranging) and humans, primarily those that infect the blood and/or neurologic tissues. Her research program includes projects that relate to the immunology, epidemiology/ecology and molecular biology of these parasites. At present, her program has a major focus on protozoal parasites that infect marine mammals and humans, many of which are shed in the feces of terrestrial animals, both wild and domestic. These links will help to illustrate Dr. Conrad's research emphases:


In 1998 my research group was invited by The Marine Mammal Center to participate in an investigation of protozoal brain disease in Southern sea otters and harbor seals in California. We isolated and characterized the protozoal parasites Sarcocystis neurona and Toxoplasma gondii from sea otters and harbor seals with protozoal myeloencephalitis in California. We also developed antibody detection to improve diagnosis, demonstrated the high prevalence of infection and mortality due to T. gondii in California sea otters and conducted epidemiologic studies to determine risk factors for transmission of T. gondii to sea otters in California. The results of our sea otter studies provided the basis for our current research which is focused on protozoal pathogen pollution in coastal ecosystems and the ecology of infectious diseases that are transmitted from terrestrial animals to marine wildlife. In this context, we are particularly interested in zoonotic parasites, like T. gondii and Cryptosporidium species, which are transmissible from domestic and wild animals to humans, as well as marine mammals. We are evaluating the ability of filter-feeding bivalves to serve as bioindicators of fecal contamination, providing clues to contributing sources of the fecal load into aquatic ecosystems. We developed quantitative molecular methods, including TaqMan PCR, for the detection and genotypic analysis of these protozoal parasites which are shed in the feces of animals and contaminate watersheds. Identification and characterization of protozoal parasites in bioindicator species and sentinel wild animals, such as sea otters, can provide valuable clues to the significance and sources of fecal pollution in our watersheds and marine environment. Some sources of fecal contamination are controllable, and as we identify contributing sources, we can take steps to better manage human and animal wastes so as to ensure a sustainable and healthy environment.

Our desire to further investigate the ecology of the zoonotic protozoan T. gondii as it is transmitted from the terrestrial hosts (wild and domestic felids) into the marine environment has been made possible with the recent award of an NSF-NIH Ecology of Infectious Disease Fogarty Grant Award in October 2005. In conjunction with these studies we have initiated an investigation into the ecology of S. neurona in coastal California. {Please email for more information}

Lillian Cruz-Orengo, Ph.D.

Neuroimmunology, sexual dimorphisms, blood-brain barrier

VM: Anatomy, Physiology & Cell Biology

Multiple Sclerosis (MS) is a devastating disease and the second leading cause of neurologic deficits in young adults, characterized by the  pathological trafficking of autoreactive-leukocytes into the central nervous system (CNS). Sadly, MS exhibits a high sex-bias, affecting three times more women than men. Women commonly exhibit the relapsing-remitting (RRMS) form of the disease, suggesting a role for sex steroids in the neuropathogenesis of MS. The mechanisms underlying sex differences in MS and whether they predominately affect immune responses, CNS susceptibility to inflammation, or both, are unclear. Specifically, my research focuses on sexual dimorphism of the blood-brain barrier (BBB) microvasculature as a relevant contributor to MS neuropathogenesis with the purpose of developing sex-specific therapeutic targets. Towards this goal, we are dedicated to uncovering the molecular mechanism underlying changes in apicobasal polarity of the BBB. Using the chemokine ligand CXCL12, a key regulator of immune trafficking into the CNS as a biomarker we hope to understand how BBB polarity is differentially regulated in females during CNS autoimmunity aiming to the development of treatments that will improve the quality of life of women suffering from RRMS.

Sonja Dieterich, PhD

Department of Radiation Oncology

Dr. Dieterich’s expertise is in the area of medical physics, specifically stereotactic radiosurgery, small field dosimetry and respiratory motion management.

My Research interest: On the human side of Radiation Oncology, I have been working in the field of stereotactic radiosurgery (SRS) for over a decade. SRS delivers very high doses of radiation with submillimeter precision to tumors; early results in local control far exceed traditional radiation regimens. While this treatment modality for cancer has gone from novel phase I trials to general clinical acceptance during this time, much is still unknown concerning the radiation biology and the treatment uncertainty. I believe much can be learned from studying naturally occuring cancers in companion animals vs. the xenografted  mouse models typically used in radiation research

Carrie Finno, DVM, PhD

Equine Genetics

Dr. Finno investigates the molecular basis for genetic diseases in the horse and other companion animals. One of the strong translational focuses of Dr. Finno's laboratory is to investigate the role of vitamin E in neurodegeneration using a well-established mouse model and a naturally-occurring model of neuroaxonal dystrophy (NAD) in the horse. Dr. Finno's research is funded by the NIH and the Center for Equine Health at UC Davis.

Potential summer projects: (1) Perform q-RT-PCR on genes of interest in spinal cord samples from Ttpa-null mice maintained on vitamin E deficient diets (2) Validate a potential biomarker in cerebrospinal fluid from NAD-affected horses (3) Identify the genetic cause of Shivers using whole-genome sequencing (4) Perform genome-wide association studies for equine neuromuscular diseases. These research projects will provide students with training in molecular techniques and provide insight into mechanisms of neurodegeneration.

Janet Foley, DVM, PHD

Center for Vectorborne Diseases

Tick-borne diseases

Summer veterinary students have several opportunities from which they can choose a summer project. The emphasis in the laboratory is disease ecology, epidemiology, and theory of infectious diseases, primarily in vector-host-pathogen systems although there are several non-vector transmitted diseases being studied as well. Students should expect to work every day all day, learn laboratory and/or field skills appropriate to their interests and project, and meet with Dr. Foley as early as possible (preferably in the spring) to confirm a project. Skills will be acquired through work with other students, technicians, and faculty in the laboratory; once a veterinary student is comfortable, they may expect to spend much of the rest of the summer obtaining data relevant to their project, analyzing the data with faculty supervision, and hopefully prepare it for publication.

Pascal Gagneux, Ph.D.

Affiliated with UC Veterinary Medical Center – San Diego

Dr. Gagneux is interested in primate molecular diversity. His lab investigates the evolutionary mechanisms responsible for the generation and maintenance of primate diversity, its potential roles in protecting populations from pathogens as well as potential consequences for reproductive compatibility. He is currently studying cell-surface molecules of sperm cells in closely related primate species. His focus is on glycans, the oligosaccharides attached to glycolipids and glycoproteins of the cell surface. The numerous parallels between the surface molecules of successful pathogens and those found on the surface of mammalian sperm, invite the analogy between internal fertilization and “extremely successful infection”. These interests examine the differences in sperm surface molecules  and sexual selection (via sperm competition and cryptic female choice) and whether such differences might contribute to reproductive incompatibility and speciation due to female immune rejection of sperm with incompatible glycoconjugates. Dr. Gagneux has studied the behavioral ecology of wild chimpanzees in the Taï Forest, Ivory Coast, population genetics of West African chimpanzees, and differences in sialic acid biology between humans and great apes with special consideration of their differing pathogen regimes. His great concern is that the current surge in interest for comparative genomics is not being translated into direct support for the conservation of primates in their endangered natural habitats.

Melanie Gareau, Ph.D.

Microbiota-gut-brain axis

VM: Anatomy, Physiology and Cell Biology

Dr. Gareau is a physiologist primarily interested in studying the microbiota-gut-brain axis. It is increasingly being recognized that the microbes that live the gastrointestinal tract, collectively referred to as the intestinal microbiota, can contribute to modulating cognition and mood. The research focus of her laboratory is in determining how manipulating the microbiota within the gut, using models of infection with bacterial pathogens or administration of beneficial probiotic bacteria, can change cognitive function, anxiety, and depression-like behaviors in mouse models of disease. Dr. Gareau has a particular interest in how the microbiota-gut-brain axis responds to stimulation with psychological stressors and under conditions of intestinal inflammation, such as in models of inflammatory bowel disease (IBD). Ongoing projects in the laboratory include studying behavior in mouse models of IBD and following pathogenic E. coli infection.

Angie Gelli, Ph.D.

Microbiology, molecular biology, host-pathogen interactions, blood-brain barrier, fungal pathogens

Dept. of Pharmacology, SOM

Over the past few years our research has focused on understanding how some pathogens are inherently capable of entering the brain, always with the underlying notion that these mechanismsmight be exploited for the development of drug-delivery systems across the blood-brain barrier for the treatment of brain disorders. My research has focused on the human fungal pathogen Cryptococcus neoformans - the leading cause of a life-threatening fungal meningoencephalitis. Approximately 625,000 people die from this infection each year around the globe mostly due to the difficulties associated with destroying the pathogen once it gets into the brain. Most patients succumb to the infection because of increased intracranial pressure and lack of adequate fungicidal drug regime. Not only does this organism represent a medically relevant pathogen with fascinating mechanisms of pathogenesis but also it serves as an excellent model system for studying other fungal pathogens with central nervous system involvement. We use a multidisciplinary approach that includes proteomics and RNA-sequencing to examine the physical and molecular changes in the brain endothelium and to identify gene products in C. neoformans that elicit these changes during attachment to- and migration across the blood-brain barrier.

Damian Genetos, Ph.D

VM: Anatomy, Physiology and Cell Biology

My research focuses upon the skeletal system, its development, and the mechanisms whereby it adapts to changes in the local microenvironment.

The skeleton responds to changes in applied loads. Under conditions of reduced use (as occurs during spaceflight or prolonged bed rest), bone is resorbed; when excess loads are applied, more bone is made, to reduce the stress placed upon them. Osteoblasts, the bone-forming cells, are responsive to a variety of stimuli, and we have begun to characterize the downstream signaling events involved in the conversion of an external load into a bone-forming response. This process is termed mechanotransduction. Current areas of research include purinergic signaling and epigenetic regulation in response to in vitro loading.

I also examine how pericellular oxygen tension affects bone cells bone turnover, and bone repair. The oxygen tension within bone can vary under certain circumstances; for example, fracture and limb unloading promotes hypoxia in osteocytes. In collaboration with a colleague at Lawrence Livermore National Laboratory, we are examining the influence of altered oxygen tension perception upon Wnt and BMP signaling in mice.

Additionally, we study how aberrant bone formation can cause pathologic conditions, such as vascular calcification.

Laurel J. Gershwin, DVM, PhD

VM: Pathology, Microbiology & Immunology

Dr. Gershwin is a veterinary immunologist who studies immunopathogenesis of disease in several species.

The laboratory studies bovine respiratory disease, with particular emphasis on Bovine Respiratory Syncytial Virus (BRSV).  Ongoing projects focus on effects of anti-viral compounds and anti-inflammatory drugs on bovine respiratory syncytial virus (BRSV) infection, testing in cattle a new potential BRSV subunit vaccine, and evaluating gene usage during acute and chronic infection. Human and bovine RSV are very similar and cause almost identical disease in their respective hosts. One of our projects has uses a human anti-RSV drug to evaluate its effectiveness in bovine calves.

The Gershwin lab is working with VMTH equine clinicians to evaluate the cellular immune response of grey horses with melanoma that are receiving Merial’s canine melanoma vaccine (off label). This DNA vaccine appears to have great potential and the goal is to document at the cell and molecular level how it works to decrease tumor growth.

STAR projects for summer can involve either of these research areas.

Philip Kass

VM: Population Health & Reproduction

"My research falls in the realm of companion animal epidemiology: the study of causes of health and disease in populations of dogs and cats. The studies that I do are non-experimental (or observational), and generally (but not always) do not involve in handling animals and do not involve laboratory work. Examples of STAR projects that I have been involved with in the past include studying factors affecting survival in dogs and cats that underwent cardiopulmonary resuscitation, factors affecting survival in dogs with peripheral nerve sheath tumors, predisposing factors to secondary glaucoma in dogs, determinants of patient outcome in cases of aortic thromboembolism, prognostic factors for recovery of function following intervertebral disk protrusion in Dachshunds, and evaluation of national trends in the submission of biopsies of suspected vaccine-associated sarcomas. These kinds of studies often begin with ideas formulated by students, and we figure out a way to study them in the time allotted for the STAR program.  I am currently trying to obtain funding to conduct epidemiologic studies into novel statistical approaches to studying possible adverse effects of vaccination on chronic diseases in companion animals."

Gregory Lanzaro, PhD

Vector Genetics Lab

Variation in maxadilan and its consequences

Maxadilan is a potent vsodilatory protein in the saliva of the sand fly, Lutzomyia longipalpis . Our observation that maxadilan is highly polymorphic was surprising. It would seem that the amino acid sequence of such a protein, with functions presumably vital to the sand fly, would be conserved. We hypothesize that hyper-variation in maxadilan has evolved as a mechanism for the avoidance of host immune response mounted against it. To test this hypothesis we propose studies aimed at determining amino acid sequence polymorphism in maxadilan from Lu. longipalpis (Aim #1). Population genetics studies will be conducted at field sites in Colombia , Nicaragua and Brazil . If variation in maxadilan does represent antigenic polymorphism and is adaptive, then it must be true that anti-maxadilan antibodies have a negative effect on vector fitness. In Aim #2 we propose a series of experiments to test this hypothesis. We will immunize hamsters with recombinant maxadilan. Flies will be fed on immunized and control animals and effects on sand fly fitness evaluated. In Aim #3 we will examine the impact of maxadilan on leishmanial infections. There is compelling evidence that the immunomodulatory activities of sand fly saliva, and maxadilan itself, enhances the establishment of parasite infections. The effects of vector saliva and specific maxadilan proteins on the pathogenesis of Leishmania chagasi will be evaluated by experimental infections (Aim #3). We have discovered that natural Lu. longipalpis populations differ dramatically in the amount of maxadilan present in their saliva. As part of Aim #3 we will conduct epidemiological field studies to determine the distribution of “high” and “low” maxadilan fly populations in relation to the distribution of visceral or atypical cutaneous disease caused by Le. chagasi . In Aim #4, we will study immunological specificity of maxadilan variants. The goal of these experiments is to determine if different maxadilan proteins illicit specific antibodies and to evaluate if these cross react (antigenic specificity).

Population genomics of the mosquito An. gambiae in Africa

Malaria control strategies based on genetic manipulation of vectors will require extensive knowledge of vector population genetics. Critical information includes: population size, patterns of gene flow, the breeding structure of populations and the effects of natural selection on individual gene loci. The overall goal of the proposed research is to provide such a background. We propose to address these questions by: (1) Characterizing spatial variation in the genetic structure of populations of Anopheles gambiae in continental Africa by determining the distribution of chromosomal and molecular polymorphisms. Representative locations will be studied in two countries: Mali in West Africa and Cameroon in Central Africa . The genetic markers we will use include chromosome arrangements, microsatellite DNA loci, and mitochondrial DNA loci. (2) Identifying physical/ecological features and relate these to spatial varoiation in population genetic structure, patterns of gene flow, and as selective forces on individual loci. Migration rates among sites will be established by measuring their genetic similarity, then inferring how much gene flow is required to maintain such observed similarity. Based on this information we will employ a GIS-based procedure termed "Wombling", which will identify areas with high and low levels of gene flow. These will be then be correlated with ecological features determined on the ground and from remote imaging. In this manner ecological features associated with high and low population densities, and also with high and low levels of gene flow can thus be identified. Such information should be helpful to vector control efforts that require an understanding of dispersal and gene flow, including genetic control and insecticide resistance management. The effects of natural selection on individual loci and segregating sites within loci will be studied by taking a population genomics approach. This approach provides the means to study the behavior of individual functional genes in nature, bridging the gap between population genetics and molecular biology.

J. Kent Leach, Ph.D.

Tissue engineering, bone, biomaterials

Research in the Leach laboratory is primarily in the broad area of TISSUE ENGINEERING. Within our research program, we seek to engineer functional replacement and temporary bridge tissues while also developing model systems to study physiological and pathophysiological tissue formation. We initially develop many of our projects with an eye toward bone tissue engineering, and these findings are subsequently applied to other areas of tissue repair including cartilage and cardiovascular engineering, as well as wound healing.

All projects in the lab are linked by the hypothesis that combinatorial approaches to tissue formation are superior to individual stimulation. More specifically, successful tissue engineering approaches will be realized upon the proper spatial and temporal presentation of cells, signaling molecules, biomaterials, and mechanical stimulation.

Plant pathology, fungal disease, epidemiology, latent infection, disease management, fungicide resistance, mycotoxins, aflatoxins

Plant Pathology, Kearney Agricultural Research & Extension Center (KARE), Parlier, CA

Dr. Michailides is a leading authority in fungal fruit tree pathology and is nationally and internationally recognized for his innovative ecological, epidemiological and plant disease management studies of devastating diseases of fruit crops such as the brown rot of stone fruit (pre-harvest and post-harvest), Botrytis gray mold of kiwifruit, pomegranate, and pistachio, fig endosepsis and smut of figs, black heart of pomegranate, Botryosphaeria blight and canker of pistachio, almond, and walnut, and aflatoxin contamination of nut crops and figs. We are doing pioneering work on resistance mechanisms of Alternaria alternata and Botrytis cinerea to various fungicides. Our studies also involve the phylogenetic analysis and taxonomy of plant pathogens attacking fruit and nut tree crops and determination of resistance of various tree cultivars to plant diseases.  We focused on detection of pathogens’ latent infections; these studies helped develop practical techniques that are used now commercially by private laboratories to help pest control advisers, California growers, and growers worldwide to make wise decisions regarding disease management. A very recent major accomplishment was the registration of an atoxigenic Aspergillus flavus strain AF36 in pistachio to reduce aflatoxin contamination of pistachio. About 77,000 acres of pistachios were treated with AF36 in 2012 for the first time and about 150,000 to 200,000 acres in 2013, 2014, and 2015. We are doing now studies to expand the label of AF36 registration for almonds and figs. Funding and collaborations on these projects include Agricultural Industries in California, the California Department of Food and Agriculture, and the ARS of the USDA. In addition, there are 9 people doing research in my plant pathology projects at the KARE Center, so there is ample opportunity for interaction with a variety of individuals in an area of fundamental and traditional plant pathology.

Mike Mienaltowski, DVM, Ph.D.

Tendon repair, stem/progenitor cell biology

College of Agriculture and Environmental Sciences

My primary research interests are based in the development, maturation, and repair of musculoskeletal tissues like articular cartilage and tendon. I am particularly interested in how differences in niche affect cells within the environment, especially for bone marrow stromal cells and tendon stem/progenitor cells. Moreover, I am interested in the physiology of usage and elite performance as well as pathophysiology from over-usage, acute and chronic injury for all musculoskeletal tissues on all species as they might be related to use, environment, or genetics, and as they might be related to the manipulation of niche and collagen regulation genes.

Christopher Miller, DVM, PhD

Center for Comparative Medicine

Dr Miller is a veterinarian, experimental pathologist and virologist who studies viral diseases and viral vaccines of humans.  His lab seeks to define the mechanisms of sexual transmission of lentiviruses and generate critical data on early events in HIV infection that will clarify the biology of transmission and inform vaccine development.

They recently found SIV can be transmitted by penile inoculation and that a full set of immune cells (B cells, plasma cells, T cells, DC) in the foreskin of male rhesus macaques and IgG and antiviral antibodies in the foreskin secretions.  They would like to know if the antiviral immune responses they found in the foreskins of SIV-infected rhesus macaques are also present in men.  Thus, they have secured IRB approval and have begun collecting foreskin secretions from HIV-infected men. Eventually they will determine how best to elicit antiviral immunity in the foreskin by vaccination.

A second current line of investigation is to characterize the initial target cells and dissemination pathways of SIV after penile inoculation using in-situ hybridization and PCR to detect viral RNA in cells and tissues.

A third current line of investigation based on the fact that semen and cervicovaginal fluids from HIV-infected men or women contain antibodies directed against the envelope glycoprotein. Although not formally proven, it is highly likely that virus resident in genital tract fluid is coated with such antibodies to form infectious immune complexes.  They want to know if these antibodies that coat virus in genital tract secretions could facilitate mucosal transmission of HIV.  Thus, they will determine the impact of pH and low concentrations of antibody on transmission efficiency following penile exposure of rhesus macaques to SIV and delineate the role of antibody in selecting transmitter/founder strains of SIV following penile exposure.

Projects for summer STAR students could potentially involve assisting conduct the laboratory assays associated with any of the 3 projects discussed above.  Please contact Dr. Miller about joining his lab meetings on Fridays at 9:30 at the CCM for more in depth discussion about possible STAR projects.

Maurice Pitesky, DVM

Department of Poultry Health and Food Safety Epidemiology

My focus is on poultry health and food safety epidemiology.   From a poultry health perspective we work on GIS based approaches toward understanding how diseases move in space and time in order to better mitigate the spread of zoonotic and epizoonitic diseases.   

From a food safety perspective my interests are primarily associated with Salmonella.  Specifically from a molecular perspective we are exploring the use of next generation sequencing technologies to better understand the virulence and pathogenicity of Salmonella Heidelberg. 

California is a national and global leader in sustainable agriculture.  Because of this, the development of ‘micro-commercial’ poultry facilities (smaller than 3,000 hens/broilers) has mushroomed.  Due to their relatively small size they are largely ignored with respect to food safety and poultry health.  Our group is interested in learning more about these type of producers in order to understand their practices from a sustainability perspective and food safety perspective.

Possible 10-week introductory research projects include:

  1. Researching the ‘transcriptome’ (i.e. gene expression) of Salmonella Heidelberg.  Student would learn Next Generation Sequencing laboratory based techniques and data analysis tools. 
  2. GIS based tools for monitoring avian diseases.  Student would use ArcGIS based software coupled with other data analysis tools to analyze avian diseases (some background in GIS preferred).
  3. Student would help develop, administer, and analyze data related to micro-commerical poultry production in California.

Colin Reardon, Ph.D.

Immunology, IBD, T1D

VM: Anatomy, Physiology, & Cell Biology

Dr. Reardon is an immunologist specializing in the regulation of immunology. He is particularly interested in the mechanisms of communication between the nervous and immune systems. Although thought of as disparate fields of study, these two systems have co-evolved and are now appreciated to influence each other. Dr. Reardon’s research focuses on the modification of immune outcomes by neurotransmitters, and on the recently discovered production of the neurotransmitter acetylcholine (Ach) by B- and T-cells. Dr. Reardon’s research has previously identified that the commensal microbiota is involved in the regulation of Ach production by these immune cells. . Various projects are currently ongoing in the laboratory that will seek to establish the role of specific neurons in modulating immunopathologies, including inflammatory bowel disease and diabetes. Based on this, testing of small molecule agonists, and neurostimulator devices (in collaboration with biomedical engineers) to modulate immunopathologies will be performed in the laboratory. To accomplish this a variety of complementary techniques will be used including flow cytometry, confocal and intravital microscopy.

Jesus Rivera-Nieves, M.D.

Affiliated with UC Veterinary Medical Center – San Diego

Dr. Rivera-Nieves works on the pathogenesis of Crohn’s disease. Leukocytes of the granulocytic, monocytic and lymphocytic lineages are active participants in the chronic inflammatory process. Their recruitment from the circulation is regulated by adhesion molecules and chemokine receptors interacting with their respective ligands expressed or presented by intestinal endothelia cells. These adhesive interactions represent attractive therapeutic targets for the modulation of the destructive chronic inflammatory process. Proof of concept for the viability of this strategy has been provided by the efficacy of natalizumab, which interferes with integrin alpha-4-VCAM-1, MAdCAM-1 interactions. Using novel murine models of Crohn’s-like ileitis, Dr. Rivera-Nieves has continued to explore potential molecules that may be targeted, within the leukocyte recruitment cascade.

Department of Pathology, UC San Diego

Our laboratory investigates the spread of prion diseases. We are focused on understanding the molecular basis for prion transmission between species, for example, human and animal susceptibility to prions of deer and elk, known as chronic wasting disease. To this end, we have identified a  loop region in the prion protein that has a major impact on the cross-species transmission of prions. We also study how the biophysical properties of the prion aggregate enable or prevent prion spread into the brain, leading to fatal neurodegeneration.

A second area of interest is in understanding the molecular basis of a highly prevalent amyloid disease that is occurring in island foxes off the coast of southern California.

We would welcome veterinary students to our laboratory at UC San Diego to participate in projects related to either prion disease or island fox amyloidosis.

Ellen E. Sparger DVM, Ph.D., DACVIM

VM: Department VM Medicine and Epidemiology

Research Interests:
SIV vaccine development using attenuated rhesus CMV vaccine vectors with TLR 5 ligands as adjuvants.
Assessment of antiviral cellular immune responses in the prevention of FIP in cats infected with feline infectious peritonitis coronaviruses.
Assessment of receptor tyrosine kinases (RTK) as targets for cancer therapeutics in feline oral squamous cell carcinoma (OSCC).

Project Appropriate for a Star Student Summer Project:
A feasible project for a Star Student would involve examination of tumor biopsies from clinical cases of feline OSCC for expression and mutation of specific RTKs. This project would include extraction of DNA and/or RNA from tumor tissues followed by PCR amplification of sequences specific to RTKs, including epidermal growth factor receptor (EGFR) and cKit and possibly other RTKs. PCR products would next be sequenced for detection of possible mutations involving activation domains of these proteins. The student involved in this project would perform research in the laboratory of Dr. Sparger but also work with Dr. Katherine Skorupski in the Veterinary Oncology Service to facilitate the collection of biopsies from clinical patients as well as become familiar with this significant cancer entity in cats for which there is no effective therapeutic protocol. Assimilation of clinical data with correlation of RTK expression and sequence will require the student to work closely with both Drs. Sparger and Korupski. Assessment of RTKs in feline OSCC will be critical for determination of which tyrosine kinase inhibitors currently in use for human OSCC, might be effective for feline OSCC as well. This project is part of a larger effort by Drs. Sparger, Korupski, Michael Kent, Boaz Arzi, and Brian Murphy to characterize feline OSCC as a model for human head and neck cancer.

Liz Stelow, DVM, DACVB

VMTH Behavior Service

Research interests: Companion Animal Behavior and Welfare

The Behavior Service does research on many aspects of companion animal behavior, welfare, and the human-animal bond. Current studies involve the role of environmental stressors and personality on the development of urolithiasis in cats and the transition of singly-housed colony Orange Winged Amazon (OWA) parrots into a co-housing setting.

The best opportunity for a STAR project is within the OWA study. Recent laboratory animal housing guidelines are driving the changes in housing for these birds and little existing research is available to educate the transition process. Those factors make this a groundbreaking research project, several aspects of which could be tailored to a stand-alone STAR project for the right student.

Other student-proposed research ideas in the area of animal behavior will be considered individually.

Nam K. Tran, PhD, MS, FACB

Department of Pathology and Laboratory Medicine

My expertise is in clinical chemistry and point-of-care testing for critical care and emergency settings. This includes the development and implementation of innovative biomedical devices and technologies for improving the quality of patient care. These technologies include molecular pathogen detection methods for early detection of sepsis, novel biomarkers of organ dysfunction (e.g., acute kidney injury, myocardial infarction, etc), and point-of-care devices (i.e., medical testing at or near the site of patient care) for testing in emergency medicine and critically ill populations. Our team works closely with Biomedical Engineering, as well as the Divisions of Burn Surgery, and Trauma/Emergency Surgery from the School of Medicine. We are also heavily involved with clinical trials including a large multicenter randomized controlled study evaluating the impact of quantitative, PCR-based detection of Staphylococcus aureus in burn sepsis patients. Translational studies with the veterinary medicine involve the use of anti-fibrinolytic therapy in severe hemorrhage models (e.g., swine and sheep), and pharmacokinetic/pharmacodynamic (PK/PD) modeling of drugs in both animal and human models of injury.

James S. Trimmer, Ph.D.

Director, UC Davis/NIH NeuroMab Facility

James S. Trimmer studies how voltage-gated ion channels are modulated in response to physiological and pathophysiological alterations in hippocampal neuronal activity. His primary experimental approach is to manipulate hippocampal neuronal activity, in either animals in vivo, in organotypic slice cultures or in dissociated neuronal cultures, and analyze effects on phosphorylation as a regulator of ion channel expression, localization and function. These studies use time-lapse and confocal imaging, patch-clamp recording, analyses of phosphorylation state employing phospho-specific antibodies and mass spectrometry, immunohistochemistry, and immuno-electron microscopy. Much of our recent work involves the colocalization of ion channels proteins to specific sub cellular domains, a subject that would be greatly enhanced by studies at the ultra structural level. Access to this highly specialized technology is absolutely essential for our future research plans.

Renée Tsolis

Department of Medical Microbiology and Immunology, School of Medicine

Dr. Tsolis is a microbiologist studying host-pathogen interactions leading to disease during infection. Her laboratory uses a variety of animal models to study how two groups of zoonotic pathogens, non-typhoidal Salmonella and zoonotic Brucella species, interact with the immune system to cause disease. For non-typhoidal Salmonella species, Dr. Tsolis' group is interested in learning why underlying co-morbidities such as malaria and malnutrition increase the incidence of death from systemic infection in the developing world, and her laboratory has developed mouse models to gain insight into immunomodulatory effects of Vitamin A deficiency and malaria. For Brucella, the laboratory has developed models to understand both chronic infection that this group of organisms causes within the mononuclear phagocyte system and to interrogate placental infections in pregnant animals that lead to abortion in domestic animals. Collaborations with UCD research Dr. Luckhart in the Medical Microbiology department, Dr. McSorley in the Center for Comparative Medicine and Dr. Stephensen in the USDA Western Human Nutrition Research Center have been instrumental in establishing this interdisciplinary research program. The long-term goal of Dr. Tsolis' work is to uncover basic principles of how bacterial pathogens manipulate the immune response to cause disease and ensure their transmission to the next host.

Laura S. Van Winkle, Ph.D., DABT

VM: Anatomy, Physiology & Cell Biology

My research focus is on toxicology and pulmonary cell biology. I study cellular responses in the lung.. Airways are a key site for many human lung diseases such as asthma, bronchitis, cystic fibrosis and lung cancer. Exposure to toxic air pollutants contributes to development of these diseases in humans and animals. We utilize unique in vivo and in vitro models to study airway epithelial injury and repair in diverse species from mice to monkeys. We have a substantial archive of tissue sections.  My laboratories are located at the Center for Health and the Environment. Projects available include studies of: 1) The effect of inhaled particles on airway toxicology and histopathology in rats 2) Effect of inhaled toxic vapors, such as naphthalene on cytotoxicity in the nose and lung 3) Using nanoparticles to understand ultrafine particle dosimetry.

Students are invited to participate in any of these ongoing projects. Students may also conduct an original project of special interest to be completed during the summer session. Ongoing research is supported by funding from several grants from NIH.

Frank J.M. Verstraete, DrMed Vet, MMed Vet, DAVDC, DECVS, DEVDC

VM: Surgical and Radiological Sciences

My primary research interest is comparative oral pathology: the study of oral and dental diseases, as well as temporomandibular joint problems, in various species, including the similarities and differences in nature and occurrence of these diseases.

The examination of mammalian skull collections for dental and temporomandibular lesions is an established method of determining the nature and prevalence of oral pathology in a particular species. If performed correctly, such studies can reveal valuable information pertaining not only to the dental diseases occurring in the species, but also to systemic diseases, diet, and behavior. Such studies may also contribute to the understanding of oral diseases in related domestic species.

The California Academy of Sciences in San Francisco and the University of California - Berkeley house a treasure-trove of skulls and are within driving distance from Davis. Their Department of Ornithology and Mammalogy and Museum of Vertebrate Zoology are eager to make their collections available for studies in comparative dental and temporomandibular joint pathology.

Potential projects for STAR Students in 2016 are:

The dental pathology of the black bear (Ursus americanus), grizzly bear (U. arctos spp.) and polar bear (U. maritimus)
The dental pathology of the Virginia opossum (Didelphis virginiana)
The dental pathology of the coyote (Canis latrans)
The dental pathology of the gray wolf (Canis lupus)
The dental pathology of the red fox (Vulpes vulpes)

Joseph Vinetz, M. D.

Affiliated with UC Veterinary Medical Center – San Diego

Department of Medicine, UC San Diego

Dr. Joe Vinetz is an infectious disease clinician and scientist investigating brucellosis, malaria, and leptospirosis. One student summer project would be to assess the public health effect of goat vaccination on human brucellosis in Peru.  Brucellosis due to Brucellosis melitensis has long been endemic in Peru.  From 2005-2010, the human brucellosis incidence markedly declined, which seems to be due to vaccination of goats with the Rev-1 vaccine.  Dr. Vinetz has high level contacts in the Peruvian Office of General Epidemiology, the Peruvian Ministry of Agriculture and the Peruvian National Institute of Health, which, in combination with faculty contacts based at Universidad Peruana Cayetano Heredia and the University of California San Diego, will allow a motivated student to obtain country-wide data towards analyzing the human and animal brucellosis trends in Peru.
