Analysis of peripheral blood T CM and T EM populations. Memory subsets were defined on CD28 expression within the CD95+ T cell population before and after infection under different conditions of replication permissivity. (a) Representative result illustrating the gating strategy based on CD28 expression. Comparison of frequencies of global TCM and TEM CD4+ (b &c) and CD8+ (d &e) T cell populations before and after chronic SIV infection. Statistically significant differences are shown as ρ values determined by paired t-test.
