Abstract
The effects of recombinant gp41 (rgp41) protein of the human immunodeficiency virus type 1 (HIV-1) on interleukin 10 (IL-10) expression and production using human peripheral blood mononuclear cells was investigated. Expression of IL-10 mRNA was demonstrated within 3 h of cell exposure to endotoxin-free rgp41 by RT-PCR and Northern blot analyses in a time- and dose-dependent manner. IL-10 protein was detected in the supernatants of peripheral blood mononuclear cells following stimulation with rgp41 also in a dose dependent manner. Fractionation of peripheral blood mononuclear cells showed that purified monocytes but not purified T-lymphocytes induced expression of IL-10 mRNA by rgp41. Recombinant HIV-1 gp120 exhibits similar influences on the induction of IL-10. These results indicate that both of these components of envelope proteins may play an important role in HIV related immunomodulation by influencing regulatory functions of monocytes and macrophages.
