HIV-Specific CD4+ T Cells May Contribute to Viral Persistence in HIV Controllers

Abstract excerpt

BACKGROUND: Human immunodeficiency virus (HIV)--infected individuals maintaining plasma HIV RNA levels <75 copies/mL in the absence of therapy ("HIV controllers") often maintain high HIV-specific T cell responses, which likely contribute to the control of viral replication. Despite robust immune responses, these individuals never eradicate HIV infection. We hypothesized that HIV-specific CD4(+) T cells might...
