Even though untrained T-cells might attack reservoir cells I believe that would be unnecessary in HIV. In cancers the residual tumor cells could re-establish themselves unless they are killed off by naive T-cells. With a modified CCR5 receptor the HIV from any erupting reservoir cells would have nowhere to attach to and would die off fairly quickly rather than reproduce.

Based on the data that we've gotten and what I've looked at, I think that what purged Brown’s HIV reservoir was this graft-versus-HIV reservoir effect [the donor T cells recognized and killed his HIV-infected cells]. We know in people with blood cancers who receive bone marrow transplants, what puts them in remission is the graft-versus-leukemia effect. The CCR5 mutation probably played a role to some degree, but I think the most important component was the graft-versus-HIV reservoir.
