Abstract

The triggering of the respiratory burst by phagocytosis via different receptors in monocytes of patients with systemic lupus erythematosus (SLE) was investigated. The superoxide anion synthesis was assayed by reduction of ferricytochrome C that was inhibited by superoxide dismutase. The mononuclear cell suspensions were triggered by IgG-coated latex, C3 complement fragment-coated and uncoated yeast (Saccharomyces cerevisiae). Superoxide generation induced by phagocytosis via Fc gamma R was decreased in monocytes of patients with SLE. On the other hand, MoAbs against Fc gamma RI, Fc gamma RII and especially CR3 could also induce superoxide anion synthesis. At the same time, superoxide generation induced by anti-CR3 could be inhibited with C3-coated yeast.
