Although combination therapy allows the suppression of human immunodeficiency virus type 1 (HIV-1) viremia to undetectable levels, eradication has not been achieved because the virus persists in cellular reservoirs, particularly the latent reservoir in resting CD4+ T lymphocytes. We previously established a simian immunodeficiency virus (SIV)/macaque model to study latency. We describe here a novel mechanism for the induction of SIV from latently infected resting CD4+ T cells. Several human cell lines including CEMx174 and Epstein-Barr virus-transformed human B-lymphoblastoid cell lines mediated contact-dependent activation of resting macaque T cells and induction of latent SIV. Antibody-blocking assays showed that interactions between …
