Tcrd

T cell receptors (TCRs) recognize foreign antigens which have been processed as small peptides and bound to major histocompatibility complex (MHC) molecules at the surface of antigen presenting cells (APC). Each TCR is a dimer consisting of one alpha and one beta chain or one delta and one gamma chain. In a single cell, the TCR loci are rearranged and expressed in the order delta, gamma, beta, and alpha.
