studies of the t-cell subpopulations responsible for suppression of the mlr and pwm responses indicate that only t gamma cells ( t cells bearing receptors for the fc portion of immunoglobulin [ ig ] g ) acted as precursors of suppressor cells for the mlr , whereas both t gamma and t non-gamma cells ( t cells not bearing receptors for the fc portion of igg ) could be activated to suppress the pwm response .
