Treatment of cells with IFN reduces HIV-1 gp120 incorporation, as well as HIV-1 envelope-mediated incorporation of ICAM-1, into virions resulting in viruses that exhibit a significantly decreased ability to become bound to CD4+ target cells |

Interaction of HIV-1 gp120 with cell-associated CD4 leads to the induction of IFN alpha; preincubation of cells with anti-CD4 or the presence of soluble CD4 during incubation inhibits IFN alpha induction |

HIV-1 gp41 or gp120 synthetic peptides induce the production of interleukin (IL)-1 and tumor necrosis factor (TNF); in contrast, gp41 or gp120 synthetic peptides are able to depress the production of interferon (IFN)-alpha, IFN-gamma, and IL-2 |
