Quiescent and activated mouse granulocytes do not express granzyme A and B or perforin: similarities or differences with human polymorphonuclear leukocytes?

Abstract excerpt

Polymorphonuclear leukocytes have been shown to use a multitude of effector functions to combat pathogens and tumors, including enzymes, defensins, and toxic products such as oxygen radicals and nitrogen oxides. Recent studies provided evidence for the expression of granzymes (gzms) and perforin (perf) within the cytotoxic arsenal of human neutrophils, the validity of which was questioned by 2 subsequent studies....
