Quantitative changes in T helper inducer (CD4+ CD45RA-), T suppressor inducer (CD4+ CD45RA+), T suppressor (CD8+ CD11b+), and T cytotoxic (CD8+ CD11b-) subsets in human immunodeficiency virus infection.
Abstract
To determine changes in subsets of CD4 and CD8 in relation to HIV infection and progression to AIDS, we quantitated peripheral blood lymphocytes obtained from 17 heterosexual controls, 22 asymptomatic HIV-seronegative and 18 HIV-seropositive intravenous drug users. 50 patients with AIDS-related complex (ARC), and 9 patients with AIDS using an EPICS "C" flow cytometer by two-color analysis. Both T helper inducer (CD4+ CD45RA-) and suppressor inducer (CD4+ CD45RA+) lymphocytes were decreased significantly in patients with ARC or AIDS. In contrast, T cytotoxic (CD8+ CD11b-) cells were significantly increased and accompanied by a significant decrease in the T suppressor (CD8+ CD11b+) subset in patients with ARC or AIDS. These results suggest that both T helper inducer and T suppressor inducer subsets of the CD4+ population and the T suppressor subset of CD8+ are depleted after HIV infection, while the T cytotoxic subset of CD8+ was increased after HIV infection.
