Human immunodeficiency virus (HIV) phenotype and interleukin-2/ interleukin-10 ratio are associated markers of protection and progression in HIV infection.
Cells collected from the SCID mouse peritoneum at 2 and 24 h after transplantation were fully susceptible to in vitro infection with HIV type 1 (HIV-1) in the absence of either IL-2 or mitogens.
Similarly, a human immunodeficiency virus promoter, whose activity is controlled through chi B factors, was found to be active in the IL-2 producing EBV-B cells, but inactive in the non-IL-2-producing cells.
The IL-2-dependent proliferation of these cells was dramatically inhibited by soluble anti-CD4 whole antibodies, F(ab')2 and Fab fragments, and also by gp 120 of human immunodeficiency virus.
Selected parameters of cellular immunity relating to cytokine gene activation and responsiveness to interleukin-2 (IL-2) were analyzed in 27 patients with active pulmonary tuberculosis and no human immunodeficiency virus type 1 infection.
Furthermore, IL-2 production by T cells in response to synthetic peptides may be a more sensitive test for exposure to HIV-1 than antibody, lymphoproliferation, or PCR tests.
Peripheral blood mononuclear cells (PBMC) were tested at 1, 5, 13, 16, and 19 months for T helper (Th) cell function by in vitro-generated proliferation and interleukin-2 production in response to four synthetic peptides corresponding to env of HIV.
Within 24-48 h after exposure to HIV in vitro, but before evidence of productive infection, greater than 25% of the monocytes became IL-2R+ with increasing numbers of IL-2R+ cells and HLA-DR levels through day 6.
rpt-1, an intracellular protein from helper/inducer T cells that regulates gene expression of interleukin 2 receptor and human immunodeficiency virus type 1.
