  1. BLT mice with indicated amount of human CD45+ (hCD45) cells and human CD3+CD4+ (hCD4) were administered with ultra-long-acting dolutegravir formulation (250 mg/kg) or placebo subcutaneously. One week after treatment mice were vaginally exposed to the indicated HIV-1 isolate. Six weeks later mice were re-exposed to HIV-1CH040. DTG-dolutegravir. Cell-associated DNA was analyzed in indicated tissue
