From: Aging related changes of circadian rhythmicity of cytotoxic lymphocyte subpopulations
Correlations between lymphocyte subpopulations in the scotoperiod. In the scotoperiod (18:00h-22:00h-02:00h) CD8+ dim correlates positively with CD16+ (r = 0.852, p < 0.001) and positively with γδTCR+ cells (r = 1.012, p = 0.05), CD16+ correlates positively with γδTCR+ cells (r = 1.676, p < 0.001). There is no statistically significant correlation in old aged subjects
