* Information From OMIM

Function: Whereas naive T cells migrate only to secondary lymphoid organs, activation by antigen confers to T cells the ability to home to nonlymphoid sites. Activated effector/memory T cells migrate preferentially to tissues that are connected to the secondary lymphoid organs where antigen was first encountered. Thus, oral antigens induce effector/memory cells that express essential receptors for intestinal homing, namely the integrin alpha-4-beta-7 (see OMIM:192975) and CCR9 (OMIM:604738), the receptor for the gut-associated chemokine TECK/CCL25 (OMIM:602565). Mora et al. (2003) showed that this imprinting of gut tropism is mediated by dendritic cells from Peyer patches. Stimulation of CD8 (see OMIM:186910)-expressing T cells by dendritic cells from Peyer patches, peripheral lymph nodes, and spleen induced equivalent activation markers and effector activity in T cells, but only Peyer patch dendritic cells induced high levels of alpha-4-beta-7, responsiveness to TECK, and the ability to home to the small intestine. Mora et al. (2003) concluded that their findings established that Peyer patch dendritic cells imprint gut-homing specificity on T cells, and thus license effector/memory cells to access anatomic sites most likely to contain their cognate antigen.
