Phagocytic function of monocyte-derived macrophages is not affected by human immunodeficiency virus type 1 infection.
1993
The immunopathogenesis of human immunodeficiency virus (HIV) infection is characterized by the failure to control opportunistic infections. Here, the direct effect of HIV on macrophage phagocytic function was studied. HIV-1-infected monocyte-derived macrophages expressed as many Fcγ and complement receptors as did control macrophages. The function of these receptors was not affected by HIV-1 infection since binding and internalization of opsonized Escherichia coli and Staphylococcus aureus were not impaired. Production of reactive oxygen species induced by stimulation of the HIV-1-infected macrophages with opsonized E. coli, zymosan, or PMA was intact
