J. Chang et al., THE MAGNITUDE OF HIV REPLICATION IN MONOCYTES AND MACROPHAGES IS INFLUENCED BY ENVIRONMENTAL-CONDITIONS, VIRAL STRAIN, AND HOST-CELLS, Journal of leukocyte biology, 56(3), 1994, pp. 230-235
It has been difficult to standardize the effects of various stimuli on
HIV replication in monocytes and macrophages in different laboratorie
s. In this study we have shown that it is possible to standardize HIV
inocula, culture conditions, and HIV antigen assay to achieve reproduc
ibility with the same viral isolate and donor monocyte and macrophage.
However, changes in serum concentration, in the strain of blood-deriv
ed 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 v
itro data suggest that genetic differences may contribute to differenc
es in HIV replication in macrophages and consequently to tissue virus
load in vivo.
