In T cells stimulated with purified phytohemagglutinin ( PHA-p ) and 4 beta-phorbol 12-myristate 13-acetate ( PMA ) addition of DM to the cultures resulted in a 60% reduction in IL-2R alpha and a 30% reduction in IL-2R beta membrane expression compared to T cells cultured in the absence of DM (p < 0.01).
