Our Lab Studies the Signaling and Transcriptional Regulation of Allergic Immune Responses and T Helper Cell Differentiation
CD4+ T helper cells (Th) are of critical importance in health and in disease. Many types of Th cell-mediated immune responses have been uncovered. Each type of Th responses is carried out by a specialized CD4+ Th subset and by a specialized innate effector cells. For example, type-2 immune responses is mounted by Th2 cells, as well as Th2 cytokine-producing innate effector cells, such as basophils, eosinophils and mast cells. Type-1 immune responses provide cellular defense against infection with intracellular pathogens, whereas Type-2 immune responses help antibody responses. Type-2 immune responses have also been shown to be dominant immune responses in allergic diseases and allergic asthma. Type-3 and 9 immune responses cells exert their biological effects on basophil and mast cell differentiation. Type-17 immune responses are critical in recruiting neutrophils, inducing chemokine production, and causing inflammation and fibrosis. Type-22 immune responses are involved in epidermal immunity and remodeling.
Our lab is interested in studying regulation of type-2 immune responses in general, specifically, we actively investigate three areas of research. Helper cell differentiation, innate type-2 effector cell differentiation, and interaction between CD4 Th cells and bone marrow allergic progenitor cells.
