1 Our data show that preincubation with anti-CD4 mAb, of the CD45RAbright/CD4+ naive and the CD45RObright/CD4+ memory human T cell populations, induces inhibition of both Erk-2 phosphorylation and Erk-2 activation by phorbol ester or anti-CD3 mAb. Phorbol Esters CD4 molecule Homo sapiens

4 In contrast, CD3 mediated JNK activation was inhibited in the memory but not in the naive CD4+ T cell population, whereas JNK activation by phorbol ester or phorbol esters plus Ca2+ ionophore was inhibited by anti-CD4 mAb in both T cell populations. Phorbol Esters CD4 molecule Homo sapiens
