Poor lymphoproliferative responses with low proportion of Gag-specific CD8 TEMRA cells in HIV-1-infected patients showing immunological and virological discordance despite prolonged suppression of plasma viremia.

We investigated in-vitro lymphoproliferative responses and T-cell subsets in 38 HIV-1-infected patients showing impaired restoration of CD4 T cells despite prolonged viral suppression (discordant), and in 42 HIV-1-infected patients showing positive immunological and virological responses to highly active antiretroviral therapy (HAART) (concordant).
