Extracellular Nef which has been implicated in disease progression and development of AIDS induces IL-10, a potent immunosuppressive cytokine, in vitro. The present study was designed to examine whether the action of extracellular Nef is a protein tyrosine kinase (PTK)-dependent event. Anti-phosphotyrosine immunoblotting reveals that recombinant HIV-1 Nef induces rapid tyrosyl phosphorylation of several cellular proteins in human peripheral blood mononuclear cells. Pre-treatment of cells with herbimycin A, but not with genistein, significantly abolishes the Nef-induced tyrosine phosphorylation of cellular proteins. Furthermore, ELISA and RNase protection assays show that herbimycin A significantly blocks Nef-induced production of IL-10 at both the protein and the mRNA level. Genistein and aminogenistein have a much less blocking effect on the ability of Nef to induce IL-10. These results provide evidence for the involvement of a herbimycin A-sensitive PTK in the signal transduction pathway for exogenous HIV-1 Nef.
