AB Infection with the human immunodeficiency virus HIV-1 is associated with
the expansion of a CD14lowCD16high monocyte subset in peripheral blood.
This subset, which represents a minor subpopulation of monocytes in
healthy individuals, increases during HIV infection and, in patients
with AIDS, may represent up to 40% of the total circulating monocyte
cell population. The CD14lowCD16high circulating monocytes co-express
MAX.1, p150,95 and HLA-DR which are typical of tissue macrophage
markers. These cells also express higher levels of intracellular
interleukin (IL)-1 alpha and tumor necrosis factor (TNF)-alpha than the
CD14highCD16low monocyte population from the same patients. The
CD14lowCD16high cells also express low levels of CD35, CD11a and CD4 in
common with normal monocytes. When cultured in vitro, monocytes from
HIV-seropositive individuals differentiated within a few hours into an
elongated fibroblastoid shape characteristic of migratory cells. Our
results suggest that the expansion of the CD14lowCD16high monocyte
subset, which produce high amount sof TNF-alpha and IL-1 alpha, may
participate in the immune dysfunction observed during HIV infection.
