Effects of 8-aminoguanosine on the toxicity of guanosine and deoxyguanosine for malignant and normal lymphoid cells.

abstract：:Highly active antiretroviral therapy (HAART) against human immunodeficiency virus type 1 (HIV-1) infection dramatically suppresses viral load, leading to marked reductions in HIV-1 associated morbidity and mortality. However, infected cell reservoirs and low-level replication persist in the face of suppressive HAART, ...
