Research/Clinical Interest
Mucosal Immunity to Enteric Pathogens
Dr. Smith's laboratory investigates the mucosalimmune responses to infectious agents and inflammatory stimuli. The mucosal cell functions currently being investigated include macrophage anergy, T regulatory and helper cell function, virus transcytosis, and the regulation of inflammation. The cellular and molecular basis for these responses are investigated by probing purified human intestinal, gastric and genital macrophages, lymphocytes, dendritic cells, T regulatory cells and epithelial cells with pathogens, including cytomegalovirus, HIV-1 and Helicobacter pylori or their purified or cloned products. The goal of these studies is to elucidate the cascade of events that regulate mucosal immune and inflammatory responses to enteric pathogens and stimuli. Understanding these responses is critical for developing novel therapeutic agents and vaccine strategies for mucosal diseases.
