Osteoimmunology (see also: biochemistry, dermatology, translational research and osteoimmunology)

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.

Nicole Baumgarth

Center for Comparative Medicine; Immunity to infectious diseases (See also: Vector-borne 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.

I am a microbiologist interested in the interaction of enteric pathogens with their hosts. We use mouse models to study Salmonella pathogenesis and host response. The main goals of this work are to interrogate mechanisms that enable typhoidal Salmonella serovars, such as Salmonella typhi, to evade innate immune recognition and mechanisms that enable non-typhoidal Salmonella serovars, such as Salmonella typhimurium, to take advantage of the host inflammatory response to edge out competing gut microbes. Furthermore, we use day-of-hatch chickens to investigate how Salmonella enteritidis colonizes the infant gut. We are also interested in how the gut microbiota confers colonization resistance against Escherichia coli and other commensal Enterobactericeae and in understanding the pathogenesis of colonic crypt hyperplasia caused by Citrobacter rodentium in mice, which is an animal model for infection with enterohaemorrhagic E. coli (EHEC).

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.

The first steps in vision begin in the rod and cone photoreceptors of the retina, which transduce photons of light into electrical signals. Our lab examines the biochemical and biophysical properties of signaling in photoreceptors, as well as the consequences of defective signaling on visual performance.  We are also trying to understand why and how photoreceptors die, which is the ultimate leading cause of untreatable blindness in humans. Photoreceptor degeneration, like all neurodegenerative diseases, leads to microglial activation and neuroinflammation. We are trying to understand the regulation of neuroinflammation, its relationship to neovascularization, and its helpful vs harmful consequences for perserving neuronal and synaptic function.  To this end, we are also exploring how resident and infiltrating immune cells and glial cells can be used to manipulate the local micro environments within the nervous system to mitigate tissue damage and promote regenerative repair.

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). MS exhibits a high sex-bias, affecting three times more women than men a phenomenon that we could replicate in the lab when inducing Experimental Autoimmune Encephalomyelitis (EAE) on SJL mice. Specifically, my research focuses on sexual dimorphism of the blood-brain barrier (BBB) as a relevant contributor to MS neuropathogenesis, aiming to develop sex-specific therapeutic targets. Additionally, we are in the developing an animal model using transgenic zebrafish to assess for changes in brain microvasculature as a result to pesticide exposure. This model of BBB disruption will lead to greater understanding of the influences environmental factors may play in this process and consequent induction of neurological and neurodevelopmental disorders.

Keywords:

Autoimmunity, sexual bias/dimorphisms, blood-brain barrier, neuroinflammation/neurodegeneration

Example of research projects:

  1. Developmental onset of sexual dimorphisms of CXCL12 apicobasal polarity among SJL mice.
  2. Assessment of therapeutic outcomes of IL-20 monoclonal antibody treatment during EAE.
  3. Clinical assessment and neuro-immune interactions IL-20RB-/- mice versus wild type.
  4. Quantitation of BBB permeability on juvenile Tg(1-fabp:DBP-EGFP:flk1-mCherry) zebrafish after Chlorpyrifos exposure.
  5. Expression of ZO-1, Claudin-5 and VE-cadherin on Tg(1-fabp:DBP-EGFP:flk1-mCherry) zebrafish during exposure to Diazinon.

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.

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.

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.

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.
