It has been difficult to standardize the effects of various stimuli on HIV replication in monocytes and macrophages in different laboratories. In this study we have shown that it is possible to standardize HIV inocula, culture conditions, and HIV antigen assay to achieve reproducibility with the same viral isolate and donor monocyte and macrophage. However, changes in serum concentration, in the strain of blood‐derived isolate (even at low passage), in the donor source of the monocyte/macrophage, and in the state of cellular maturation all influenced HIV production by these cells. The donor source of monocytes contributed as much to variability in HIV production as the HIV strain and results were reproducible when the same source was used repeatedly. These in vitro data suggest that genetic differences may contribute to differences in HIV replication in macrophages and consequently to tissue virus load in vivo. J. Leukoc. Biol. 56: 230–235; 1994.
