Receptors, Antigen, T-Cell, gamma-delta
Antigen T Cell Receptor, delta Chain; Antigen T Cell Receptor, gamma Chain; Receptors, Antigen, T Cell, gamma delta; T Cell Receptors, gamma delta; T-Cell Receptor delta-Chain; T-Cell Receptor gamma-Chain; T-Cell Receptor, gamma-delta
T-cell receptors composed of CD3-associated gamma and delta polypeptide chains and expressed primarily in CD4-/CD8- T-cells. The receptors appear to be preferentially located in epithelial sites and probably play a role in the recognition of bacterial antigens. The T-cell receptor gamma/delta chains are separate and not related to the gamma and delta chains which are subunits of CD3 (see ANTIGENS, CD3).
