Brief Summary:
Current antiretroviral therapy (ART) is highly effective to suppress plasma viral load to below the detection limit and to restore the host immunity, thus to prolong the survival of HIV-1-infected patients remarkably. However, HIV-1 will rebound to pre-treatment levels within weeks of interruption or irregular medication. The reason why HIV-1 would not be eradicated by powerful ART can be explained by that the reservoir of latent HIV-1 in resting CD4 T cells will persistently exist even long-term suppression of plasma viral RNA. Several therapeutic approaches that aim to prevent or delay viral rebound after treatment interruption, producing a post-treatment remission or functional cure of HIV-1, are being investigated. This study is to measure the size of viral reservoir and HIV-1-specific T cell response in HIV-1-infected patients during ART to help understand the mechanism of HIV-1 persistence, then to help establish a potential policy for functional cure.
