Differentially expressed genes in memory and naive CD8⁺ T cells. (A) Memory cell differentially expressed genes through resting and activated states. Twelve selected genes are presented. (B) Memory cell differentially expressed genes only in the resting states. Eight selected genes are presented. The microarray results derived from 3 independent experiments and normalized to the resting naive cells in panels A and B are presented as the mean ± SEM in log₁₀ scale. (C) Naive cell differentially expressed genes in resting and activated states. Eight selected genes are presented. The microarray results derived from 3 independent experiments and normalized to the resting memory cells in panel C are presented as the mean ± SEM in log₁₀ scale. The detailed information of these genes can be found in Table S9.
