Abstract

Human monocytes require serum components immunoglobulin G, C3/C3b, and B/Bb to exert optimal microbicidal action against ingested microorganisms. The present study was performed to find out whether these factors act by enhancing oxygen-dependent antimicrobial mechanisms. Serum enhanced oxygen consumption and superoxide production by monocytes before phagocytosis, but did not further increase these processes in monocytes that had recently ingested bacteria. Furthermore, serum did not boost iodination during intracellular killing by monocytes. Phorbol myristate acetate, N-formyl-methyonyl-leucyl-phenylalanine, concanavalin A, and concanavalin A-Sephadex all stimulated the conversion of O2 to H2O2 by monocytes, but only concanavalin A augmented intracellular killing. Reactive oxygen intermediates generated by cell-free enzymes (xanthine oxidase or glucose oxidase) in concentrations comparable to those accumulating extracellularly during incubation of monocytes containing bacteria with phorbol myristate acetate did not promote intracellular killing. The presence of catalase during phagocytosis inhibited killing, but had no effect on killing in the postphagocytic state. Monocytes deprived of glucose for 24 h showed markedly impaired O2 consumption, O2- generation, and bacterial killing; all of these effects were rapidly reversed by restoration of glucose. It is concluded that both an intact respiratory burst and extracellular serum factors are necessary for optimal killing of intracellular Staphylococcus aureus by human monocytes. Serum does not appear to act by enhancing the respiratory burst, but rather to have a separate, synergistic role, the biochemical basis of which is unknown.
