Gag CM9 tetramer responses in CD8+ T lymphocytes at necropsy. The frequency of Gag-specific CM9+ CD8+ T lymphocytes elicited by the different vaccine regimens was measured in PBMC by combined tetramer staining and cell surface phenotyping for memory T cells subsets followed by flow cytometry. The plots show the percentage of CM9+ CD8+ T lymphocytes among (A) total CD8+ T cells, (B) effector memory (CD95+CD28−) and (C) central memory (CD95+CD28+) CD8+ T lymphocytes. (D) The ratio of CM/EM among the tetramer+ CD8+ T cells is shown.
