CD1-restricted recognition of exogenous and self-lipid antigens by duodenal gammadelta+ T lymphocytes.

Gammadelta T cells are present in the mucosal intestinal epithelia and secrete factors necessary to maintain tissue integrity. Ags recognized by these cells are poorly defined, although in mice non-classical MHC class I molecules have been implicated. Since MHC class I-like CD1 receptors are widely expressed at the surface of epithelial and dendritic… CONTINUE READING
