 AB    We have demonstrated that native envelope glycoproteins of HIV-1, gp160
       can induce activation of the transcription factor, NF-kappa B. The
       stimulatory effects of gp160 are mediated through the CD4 molecule,
       since pretreatment with soluble CD4 abrogates its activity. The
       gp160-induced NF-kappa B complex consists of p65, p50 and c-rel
       proteins. The stimulatory effect of gp160 on NF-kappa B activation is
       protein synthesis independent, is dependent upon protein tyrosine
       phosphorylation, and abrogated by inhibitors of protein kinase C. The
       gp160-mediated activation of NF-kappa B in CD4 positive T cells may be
       involved in biological effects, e.g., enhanced HIV replication,
       hypergammaglobulinemia, increased cytokine secretion, hypercellularity
       in bone marrow and apoptosis.
