HIV-tat protein, like TNF, activates a wide variety of cellular responses, including NF-kappa B, AP-1, c-Jun N-terminal kinase (JNK), and apoptosis. Whether HIV-tat transduces these signals through the same mechanism as TNF is not known. In the present study we investigated the role of the T cell-specific tyrosine kinase p56lck in HIV-tat and TNF-mediated cellular responses by comparing the responses of Jurkat T cells with JCaM1 cells, an isogeneic lck-deficient T cell line. Treatment with HIV… CONTINUE READING
