Reactivity of memory CD8+ T lymphocytes to HIV-1 could potentially inhibit this residual viral replication, but is largely muted by ART in relation to suppression of viral antigen burden. Dendritic cells (DC) are important for MHC class I processing and presentation of peptide epitopes to memory CD8+ T cells, and could potentially be targeted to activate memory CD8+ T cells to a broad array of HIV-1 epitopes during ART. Principal Findings: We show for the first time that HIV-1 peptide-loaded, CD40L-matured DC from HIV-1 infected persons on ART induce IFN gamma production by CD8+ T cells specific for a much broader range and magnitude of Gag and
