Correlation of BACH2 and PRDM1 with age in healthy donors. a BACH2 mRNA expression decreased with age in CD4+, CD8+ and CD19+ (r = − 0.67, r = − 0.79, r = − 0.58, respectively) (b) PRDM1 mRNA expression upregulation with age in CD4+, CD8+ and CD19+ (r = 0.58, r = − 0.64, r = − 0.54, respectively). c The inverse correlation between BACH2 and PRDM1 mRNA expression in CD4+, CD8+ and CD19+ (r = − 0.57, r = − 0.65, r = − 0.58, respectively). Significant p values (< 0.05) and Spearman r values are shown
