A naturally occurring Tat R52W variant in brain-derived HIV attenuates transcription and may contribute to reservoir persistence
HIV-1 persistence under suppressive antiretroviral therapy (ART) remains a major barrier to eradication, yet the contribution of naturally occurring viral variation to transcriptional regulation is incompletely understood. Here, we identify an HIV-1 Tat variant (R52W) that attenuates viral transcription through the dis...
