The responses of cloned murine T cell lines to the phorbol ester, phorbol myristate acetate (PMA), were investigated. PMA alone was able to stimulate proliferation of some clones but not others. Two Lyt-2+, cloned cytolytic T lymphocyte (CTL) lines proliferated in response to stimulation by PMA alone, but several L3T4+, cloned helper T lymphocyte (HTL) lines did not. In contrast, all clones tested released lymphokines in response to stimulation by the combination of PMA and the calcium ionophore A23187. Moreover, all clones proliferated in response to stimulation by the combination of PMA and A23187. The proliferation of HTL in response to PMA + A23187 could be completely inhibited either by cyclosporine A (CsA) or by PC61.5, a monoclonal antibody directed against the murine IL 2 receptor; however, the proliferation of CTL in response to PMA alone was not affected either by CsA or by PC61.5. These results suggest that of the murine T cell clones tested, HTL proliferate in response to stimulation via an IL 2-dependent, autocrine pathway; in contrast, CTL, in addition to an IL 2-dependent pathway, may possess an additional IL 2-independent pathway of proliferation. CTL that proliferate in response to stimulation by PMA alone may be useful models in the study of T cell proliferation.
