Neutrophils in elderly rhesus macaques express lower levels of MPO.

Whole blood samples from rhesus macaques ranging in age from 5.6 – 27.8 years old were stained for surface and intracellular markers. MPO expression was measured as median florescent intensity (MFI) in neutrophils gated from single cells/live/CD45+/CD3-/CD20-/HLA-DR-/CD66abce+. (A) Spearman nonparametric correlation test was applied. (B) Unpaired Mann-Whitney U test was used to compare MPO MFI expression in the younger animals aged 5.6 – 8.8 years old with that in older animals aged 17.9 – 27.83 years old. ** P < 0.01.
