Changing epidemiology of HIV type 1 infections in India: evidence of subtype B introduction in Bombay from a common source.

abstract：:HIV patients beginning antiretroviral therapy (ART) with advanced immunodeficiency often retain low CD4+ T cell counts despite virological control. We examined proliferative responses and upregulation of costimulatory molecules, following anti-CD3 stimulation, in HIV patients with persistent CD4+ T cell deficiency on ...
