| + | The nature of the antigens recognized by gammadelta T cells and their potential recognition of major histocompatibility complex (MHC)-like molecules has remained unclear. Members of the CD1 family of lipid-presenting molecules are suggested ligands for Vdelta1 TCR-expressing gammadelta T cells, the major gammadelta lymphocyte population in epithelial tissues. We crystallized a Vdelta1 TCR in complex with CD1d and the self-lipid sulfatide, revealing the unusual recognition of CD1d by germline Vdelta1 residues spanning all complementarity-determining region (CDR) loops, as well as sulfatide recognition separately encoded by nongermline CDR3delta residues. Binding and functional analysis showed that CD1d presenting self-lipids, including sulfatide, was widely recognized by gut Vdelta1+ gammadelta T cells. These findings provide structural demonstration of MHC-like recognition of a self-lipid by gammadelta T cells and reveal the prevalence of lipid recognition by innate-like T cell populations. | ||
