Priming of macrophages for enhanced oxidative metabolism by exposure to proteolytic enzymes

Abstract

Preincubation for 10-30 min with trypsin, pronase, chymotrypsin, or papain primed macrophages to undergo a twofold to sixfold increase in oxidative metabolism, measured as release of superoxide anion or hydrogen peroxide, during stimulation by phorbol myristate acetate or ingestion of Candida parapsilosis. Preincubation of macrophages with inactivated… (More)
