Differential human immunodeficiency virus expression in CD4+ cloned lymphocytes: from viral latency to replication

J Virol. 1992 Jun;66(6):3966-70. doi: 10.1128/JVI.66.6.3966-3970.1992.

Abstract

By using cloning methodology, 13 CD4+, CD8-, CD45RO+, and CD29+ clones, isolated from human immunodeficiency virus (HIV)-negative donors, have been characterized and tested regarding their susceptibility to two strains of HIV type 1 (HIV-1). Infected clones possess integrated provirus. Only six are able to replicate HIV-1, while seven may normally grow without cytopathic effect and without viral replication. These results argue that all CD4+ lymphocyte clones may be infectable but that a heterogeneity exists regarding their abilities to replicate HIV-1.
