Investigators hypothesize at least a 0.25-log reduction in cell-associated HIV DNA at one-year intervals in study participants who have a demonstrated anti-proliferative response to MMF treatment. Investigators hypothesize that cell-associated HIV DNA will undergo a shift from predominant residence in TCM and TEM to predominant residence in TN and TSCM. In regards to our sub-study, investigators predict that reservoir depletion will occur with equivalent rates in blood and GALT.
