Receptors antigen t-cell

receptors, antigen, T-cell
molecules on the surface of t-lymphocytes that recognise 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 alphabeta (receptors, antigen, T-cell, alpha-beta) or gammadelta (receptors, antigen, T-cell, gamma-delta) chains.
