Table 1 The effect of age on NK cell number
From: Ageing is associated with a decline in peripheral blood CD56bright NK cells
Age(yrs) | N = | Mean NK cell μl/blood (+/- SD) | Mean NK cells % of lymphocytes (+/-SD) |
|---|---|---|---|
20–40 | 25 | 194.9 (+/- 140.4) | 9.25 (+/- 6.1) |
40–60 | 23 | 187.6 (+/- 144.5) | 10.59 (+/- 7.5) |
> 60 | 67 | 205.8 (+/- 184.0) | 11.22 (+/- 9.1) |
