the tumor cytolytic activity , as well as the number of cells recovered from interleukin 2 ( il-2 ) -stimulated cultures , was enhanced by the addition of the pk-c stimulator , phorbol dibutyrate ( pdbu ) , but not non-pk-c-activating phorbol ester analogues while the ca2+ ionophore , ionomycin , did not significantly alter development of il-2-induced tumor cytolytic activity nor enhance cell yield .
