Research Abstract
APOPTOSIS IN THE IMMUNE SYSTEM: Apoptosis is one of the most fundamental biological mechanisms for the selection of T cell repertoire,maintenance of cellular homeostasis, and deletion of self-reactive lymphocytes. A number of genes and their products are known to regulate the process of Apoptosis. Our current research focuses on the molecular mechanisms of apoptosis in naive and various memory subsets, including central and effector memory CD4+ and CD8+ human T cells in aging, and primary immunodeficiency.
GENETIC BASES OF PRIMARY IMMUNODEFICIENCY DISEASES: There are more than 120 primary immunodeficiency diseases, which represent a paradox of failure to respond to non-self, and response to self antigens resulting in increased susceptibility to microbes and increased incidence of autoimmunity. We are interested in defining genetic bases in some of these patients with primary immunodeficiency diseases that are regularly seen in our Jeffery Modell Center for Primary Immunodeficiencies. We have defined several novel mutations including novel mutations in Rag2 gene in a patient with Ommen's syndrome (a subtype of Severe Combined Deficiency), novel mutation in AICD gene in Hyeper IgM syndrome patient.
B CELL BIOLOGY: Our research on B cells is focused on understanding theeir role in innate immune response (i.e. signaling via TLR in the production of cytokines and growth factors), and functions in both primary immunodeficiency diseases, and human aging.
DENDRITIC CELL BIOLOGY: We are interested in defining impact of aging and alterations in primary immunodeficiencies to understand cellular and molecular mechanisms of paradox of inflammation, autoimmunity, and immunodeficiency.
