The transcription factor NF-κB has been implicated in the mitogen-induced expression of several genes that are critical for the immunologic function of T cells such as those encoding IL-2 and the IL-2Rα chain (IL-2Rα). We show here that NF-κB is induced in T cells activated by Ag, anti-CD3 antibody, or allogeneic stimulation. The induction of NF-κB via the TCR was dependent on protein kinase C. IL-2, which also activates IL-2Rα expression and proliferation in T cells, was not able to induce NF-κB. TCR-mediated induction of NF-κB suggests a central role for this factor in activated T cells and also provides a mechanism for activation of latent HIV provirus during the normal immune response.
