Abstract

alphabeta T cell receptors (TCRs) have traditionally been viewed as receptors for peptide antigens presented by either Major Histocompatibility Complex (MHC) class I (for CD8 T cells) or MHC class II (for CD4 T cells) antigen-presenting molecules. However, it is now clear that some T cell lineages express TCRs that are specialized for recognition of lipid-based antigens presented by the MHC class I-like CD1 family. Recently, the molecular basis for the TCR recognition of glycolipid antigens presented by CD1d has revealed an evolutionarily conserved-docking mode that is distinct from that of peptide-based recognition. T cells carrying these receptors follow a unique developmental pathway that results not only in unconventional antigen specificity, but also seemingly exaggerated functional capabilities, which makes these cells and their antigens highly attractive targets for immunotherapeutic manipulation.
