Golly.
I have not seen literature describing an age-associated correlation of
macrophage killing. I'm not sure why you would think there is one. Do
you believe that their is an age-assoc. decline in macrophage numbers, or
phagocytosis? I find this to be a curious question and am interested in
learning your reasons behind this query.
