Peripheral blood monocytes are resistant to productive human immunodeficiency virus type 1 (HIV-1) infection in vitro immediately after isolation. No viral cDNA (either early or late transcripts) was detected by PCR in monocytes exposed to virus on the day of isolation. In contrast, in monocytes cultured for as little as 1 day, initiated and completed reverse transcripts were readily detectable within 24 h of infection with both HIV-1(Ba-L) and primary isolates. The levels of initiated, partially completed, and completed viral DNA copies found 24 h after infection increased progressively with time in culture before infection. Unlike quiescent T lymphocytes, there appeared to be no block or d..
