Immunodominant HIV-1 Cd4+ T cell epitopes in chronic untreated clade C HIV-1 infection.
BACKGROUND: A dominance of Gag-specific CD8+ T cell responses is significantly associated with a lower viral load in individuals with chronic, untreated clade C human immunodeficiency virus type 1 (HIV-1) infection. This association has not been investigated in terms of Gag-specific CD4+ T cell responses, nor have clade C HIV-1-specific CD4+ T cell epitopes, likely a vital component of an effective global HIV-1 vaccine, been identified. METHODOLOGY/PRINCIPAL FINDINGS: Intracellular cytokine ...Expand abstract
