A main goal of research in the Brown Lab centers on the genetics of host resistance to viral infection, and the role of natural killer (NK) cells in viral immunity. We aim to understand (1) how genetic variation shapes both innate and adaptive immune cell features, and how these differences further affect immune cells needed to detect and clear viral pathogens; (2) how NK cell effector function is acquired and regulated by both genetic and environmental influences; and (3) how NK responses to immune stimulation can specifically regulate adaptive immune outcomes.
My name is Jamieson Bourque, MD, MHS, and I am an Associate Professor of Medicine and Radiology with advanced training and expertise in multimodality cardiovascular imaging. I am the Medical Director for Nuclear Cardiology and the Stress and Echocardiography Laboratories. I have long-standing research interests in the diagnosis and prognosis of ischemic heart disease and the role of exercise parameters and workload in this disease. I am interested in patients with symptoms of ischemia and no obstructive epicardial coronary disease (INOCA) and the relationship of coronary microvascular dysfunction and the impact of these disease processes on functional status and quality of life. I also have research and clinical interests in predictive analytics.
The focus of our work is on the use of dendritic cells (DC) as immunotherapeutic vaccines against melanoma and other malignancies. DC are extremely potent antigen presenting cells (APC) that express MHC class I and class II molecules and an array of costimulatory molecules that are required for the activation of naïve T cells. Thus, DC make ideal candidates as vaccine delivery systems for the generation of immune responses against tumors. Recent studies have demonstrated that many patients make immune responses against their tumors, though they usually ultimately fail to control tumor outgrowth. Extensive investigations have identified many of the proteins that are the targets of these immune responses, and further defined the MHC class I and MHC class II-restricted peptides derived from tumor antigens that are presented to cytotoxic CD8+- and helper CD4+ T cells respectively. DC pulsed with such peptides are the basis of the vaccines that we are currently studying.

My research is focused on elucidating the immunoregulatory mechanism by Hepatitis C virus (HCV). HCV is a global health concern causing severe liver disease. T cell responses have been reported to play a pivotal role in controlling HCV infection. However, HCV-specific T cell responses are significantly impaired in chronic HCV patients. Recent studies in my lab demonstrate that exosomes released from HCV-infected hepatocytes display TGF-beta at the exosome surface and suppress T cell responses. Exosomes are small membrane-bound extracellular vesicles and serve as natural carriers of signaling molecules to promote cellular crosstalk. We are currently working to identify the cellular and molecular mechanism for the role of exosomes released from HCV-infected hepatocytes in regulating the host immunity and promoting the development of liver fibrosis.
Our laboratory is specifically interested in the regulation of vascular cell commitment, differentiation and cell cycle progression, and defining signaling pathways that modulate these processes.

In the Walsh lab, we study Hematopoietic stem cells which produce multiple blood cell types and replenish themselves through a self-renewal process. As with all cells, hematopoietic stem cells accumulate somatic mutations with age. While most mutations have little or no effect on cellular fitness, some mutations will occur in “driver” genes that enable their positive selection. Thus, the mutant cells can outcompete neighboring wild-type cells leading to a clonal expansion. Notably, these mutant hematopoietic stem cell clones give rise to progeny immune cells that harbor the same mutant allele, and it has been shown that these mutations can functionally corrupt the circulating immune cell pool. Clonal expansions in blood cells have been found to occur in relatively healthy individuals who lack overt signs of blood cancer. This pre-cancerous condition has historically been referred to as “clonal hematopoiesis” and more recently as “clonal hematopoiesis of indeterminate potential” or “age-related clonal hematopoiesis” to distinguish it from the clonal expansions that occur in malignant blood disorders.
Dr. Jeffrey Wilson has a major clinical and research focus in the α-Gal syndrome and over the past two years has been studying antibody responses to SARS-CoV-2 in response to natural infection and vaccination. Working with Dr. Platts-Mills and colleagues in the Division of Allergy and Immunology, he has been involved in studies to characterize the prevalence of alpha-gal sensitization in the community and investigations into different ways that α-Gal syndrome can manifest.

Dr. Wilson is also the PI of a UVA employee vaccine study and an IRB-approved study that will assess in vivo immunologic responses to α-Gal in patients challenged with traditional pork vs. genetically modified pork that lacks α-Gal. Dr. Wilson is the recipient of an AAAAI Faculty Development Award looking, in collaboration with Coleen McNamara, MD and Angela Taylor, MD, MPH in cardiology, at a putative association between α-Gal sensitization and coronary artery disease.

Over the last several years, in active collaboration with Dr. John Luckey and Dr. James Gorham, we have developed a series of novel murine models of red blood cell (RBC) metabolism, G6PD deficiency, immune response to RBC alloantigens, and anti-D. It is thus very fortuitous that in the last decade, Dr. Gorham and Dr. Luckey, and now my group (Zimring lab) have each joined the UVa school of medicine. Combined with other groups focusing on RBC biology (e.g. Dr. Goldfarb) and with other talent in transfusion and blood biology already at UVa, there is an aggregate synergy around advancing our understanding of Transfusion Medicine, RBC biology, and Transfusion/RBC immunology. At the cost of wonky pathology humor, it is an agglutination of RBC talent and interest.
Research in our laboratory is focused on discovering the mechanisms that control stem cell fate. We study in vitro differentiation to gain insight into stem cell behavior during normal development and disease, and we study in vivo development to gain insight into the derivation of clinically relevant cell types for regenerative therapy. In order to study the complex mixtures of rapidly changing cell types that exist in these in vitro and in vivo systems, we are building experimental and computational tools that track cell populations as they change over time with molecular characterization at the single-cell level. Using these tools, our goal is to define the fundamental principles of cellular pluripotency and differentiation.
