Intriguingly, total WBC count had no difference between the young and aged groups, but there were marginally significant alterations in WBC differentials: the percentage of total lymphocytes (35.94 ± 7.48 vs 33.98 ± 8.63, P = 0.07) declined with age (Table 1 ), while the proportion of total monocytes (7.40 ± 1.64 vs 7.87 ± 1.90, P = 0.056) was elevated (Fig. 1 A), consistent with the previously depicted age-associated shift towards the myeloid lineage differentiation.
