Effect of Bacterial Antigens on Local Immunity
The ability of intestinal lymphoid cells to migrate to, and localize in, other mucosal tissues, e. g. the respiratory and genitourinary tract, and other secretory glands, underlines the relevance of the gut-associated lymphoid tissue (GALT) in the local immune response. Following antigen presentation, activated cells from the GALT pass from the lymphatics to the blood circulation via the ductus thoracicus, disseminate into distant mucosal tissues where the cells further proliferate and differentiate into memory and effector cells. In fact, it is known that enteric ingestion of microbial antigens induces S-IgA responses in remote external secretions.1,2
