| Outline of Final Research Achievements |
HIV-1 infected cells persisting under antiretroviral therapy (ART) are targets for therapeutic development for the cure of HIV-1 infection. We investigated the kinetics of proviral DNA (pDNA) using qPCR for 840 specimens of peripheral blood mononuclear cells (PBMC) of 59 cases under long-term treatment from 1996. When untreated, pDNA was 284 copies on average per million PBMCs, but it decreased with ART initiation. On the other hand, in the course of long-term treatment, pDNA plateaued at a certain level that varies from case to case. In cases with chronic complications, it was inferred that there are different patterns in the kinetics of pDNA under ART, such as repeatedly increasing and decreasing greatly.
