abstract：:Despite the success of antiretroviral therapy (ART) in decreasing mortality for HIV-1-infected patients, ART has not cured the disease. A persistent viral reservoir in the T cells of HIV patients receiving potent ART is a significant barrier preventing eradication of HIV infection. We will briefly review what is known...
