t-cell antigen receptor meaning
[Medicine]
Molecules on the surface of T-lymphocytes that recognize and combine with antigens. The receptors are non-covalently associated with a complex of several polypeptides collectively called CD3 antigens (ANTIGENS,CD3). Recognition of foreign antigen and the major histocompatibility complex is accomplished by a single heterodimeric antigen-receptor structure,composed of either alpha-beta (RECEPTORS,ANTIGEN,T-CELL,ALPHA-BETA) or gamma-delta (RECEPTORS,ANTIGEN,T-CELL,GAMMA-DELTA) chains.
