    env 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 PubMed
    env 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 PubMed

    Envelope surface glycoprotein gp160, precursor env IFN alpha treated effector clones (gp120+CD8+ HPB-ALL/HIV) simultaneously downregulate CD8 expression and upregulate expression of both major histocompatibility antigen complex class I (MHC-I) and HIV-1 gp120/gp160 PubMed

    RefSeqs maintained independently of Annotated Genomes

    These reference sequences exist independently of genome builds. Explain

    These reference sequences are curated independently of the genome annotation cycle, so their versions may not match the RefSeq versions in the current genome build. Identify version mismatches by comparing the version of the RefSeq in this section to the one reported in Genomic regions, transcripts, and products above.
