We have succeeded in growing the HTLV-IIIB strain of human immunodeficiency virus type 1 (HIV-1) in cultured human thymic epithelial (TE) cells. Expression of the HIV-1 proteins p17 and p24 was detected by immunofluorescence and reached a peak at 3 days after infection. Antigen capture and reverse transcriptase assays were used to detect HIV-1 in culture fluids, with positive results also being realized. The infection was cytolytic; cellular disarrangement, increased numbers of Hassall's corpuscles, and giant cells first appeared in monolayers of TE cells at 2 days after inoculation. By 4 days these changes were increased, and by 7 days, retraction and involution of TE cells were evident. The infection of TE cells by HIV-1 was blocked by preincubation with monoclonal OKT4A antibodies directed against CD4 target molecules.

D006678 HIV Human immunodeficiency virus. A non-taxonomic and historical term referring to any of two species, specifically HIV-1 and/or HIV-2. Prior to 1986, this was called human T-lymphotropic virus type III/lymphadenopathy-associated virus (HTLV-III/LAV). From 1986-1990, it was an official species called HIV. Since 1991, HIV was no longer considered an official species name; the two species were designated HIV-1 and HIV-2.
