SO Proc Natl Acad Sci U S A. 1995 Jun 6;92(12):5563-7. Unique Identifier : AIDSLINE MED/95296351 AB The human immunodeficiency virus 1 (HIV-1) replicates more efficiently in T-cell lines expressing T-cell receptors derived from certain V beta genes, V beta 12 in particular, suggesting the effects of a superantigen. The targeted V beta 12 subset was not deleted in HIV-1-infected patients. It was therefore possible that it might represent an in vivo viral reservoir. Viral load was assessed by quantitative PCR with gag primers and with an infectivity assay to measure competent virus. It was shown that the tiny V beta 12 subset (1-2% of T cells) often has a higher viral load than other V beta subsets in infected patients. Selective HIV-1 replication in V beta 12 cells was also observed 6-8 days after in vitro infection of peripheral blood lymphocytes from normal, HIV-1 negative donors. Viral replication in targeted V beta subsets may serve to promote a biologically relevant viral reservoir.
