Abstract
The presence of HIV-1 proviral DNA was determined in CD4 cells, CD8 cells and macrophages/monocytes obtained from peripheral blood of 8 HIV-1 infected persons. Using the polymerase chain reaction (PCR) we were able to detect proviral DNA in the extracts of only 10(2)-10(3) CD4 (T4) cells. In contrast, 10(5) CD8 cells did not contain detectable amounts of proviral DNA. Surprisingly, in four of our eight patients studied no HIV-1 DNA was found in macrophages. In peripheral blood, every hundred T4 cell may be infected with HIV-1.
