Analysis of peripheral blood T CM , T EM1 and T EM2 populations. Memory subsets were defined on differential expression of CCR7 and CD28 within the CD95+ T cell population before and after infection under different conditions of replication permissivity. (a) Representative result illustrating the gating strategy. Comparison of frequencies of global TCM, TEM1 and TEM2 CD4+ (b, c &d) and CD8+ (e, f &g) T cell populations before and after chronic SIV infection. Statistically significant differences are shown as ρ values determined by paired t-test.
