functional studies in several laboratories , including our own , suggest a 'division of labor ' between the alpha/beta-chain heterodimer ( t-cell receptor ) and the 3 other polypeptide chains ( t3-gamma , -delta , -epsilon ) : the t-cell receptor alpha and beta chains together recognize antigen and mhc product on the antigen-presenting target cell and an activation signal is transduced to the cytoplasmic side of the plasma membrane via the t3 complex .
