Differential expression of cytokine genes in HIV-1 tat transfected T and B cell lines.

Cytokine responses are dramatically affected when HIV-1 infected cells are activated with certain antigenic stimuli. We report the effects of HIV-1 tat gene in cytokine modulation, using HIV-1 tat transfected T (Jurkat) and B (Raji) cell lines. Studying the effect of tat and/or PMA + PHA on mRNA expression of 14 cytokines (IL-1 alpha, IL-2, IL-4, IL-5, IL-6, IL-8, IL-10, IL-12, TNF-alpha, TNF-beta, GM-CSF, TGF-beta, IFN-gamma and MIP-1 alpha) illustrated differential effects. In addition to the varied effects of tat on the steady state levels of cytokine mRNAs, tat induced the secretion of TNF-beta preferentially in both B and T cell lines, either by itself as in Raji B cell line or synergistically upon PMA + PHA stimulation as in Jurkat T cell line.
