Ageing does not change blood granulocyte bactericidal capacity and levels of complement factors 3 and 4.
The bactericidal capacity of blood polymorphonuclear granulocytes and the plasma levels of complement factors 3 and 4 did not differ between 15 aged patients and 15 young control subjects, nor did these important antimicrobial functions predict morbidity and mortality in the next 6 months.
