Ephedrine enhances HIV-1 reactivation from latency through elevating tumor necrosis factor receptor II (TNFRII) expression.

ABSTRACT: HIV-1 persists during antiretroviral therapy (ART) due to long-lived and proliferating latently-infected host cells, with the outcome being an incomplete cure. The latently-infected cells, or reservoir cells, are transcriptionally absent and invisible to the immune response. Elimination of latency is one strategy in activating virus production, making it visible to immune clearance. We previously showed that Ephedrae herba reactivated HIV-1 from latency. In this study, we used ephedrine, a major component of Ephedra herba, to reactivate HIV-1 from latency. The results showed that ephedrine enhances HIV-1 reactivation in the presence of TNFα. Combination treatment demonstrates a synergistic effect of HIV-1 reactivation compared to TNFα alone. Ephedrine treatment shows a higher TNFRII expres
