Abstract:
:Human mononuclear cells stimulated with soluble IgG aggregates generated chemiluminescence, a response attributable to monocytes. Some requirements of this reaction were examined by preincubation of the cells with a variety of inhibitors. The protease antagonists TPCK and TLCK, the phospholipase inhibitors quinacrine and BPB, and the calcium channel blocker verapamil were all inhibitory at micromolar concentrations. The oxygen metabolite scavengers SOD and catalase were less inhibitory. These findings are consistent with a major role for arachidonic acid metabolites in the generation of light. Modulation of monocyte Fc-mediated chemiluminescence also occurred by preincubation of the cells with Fc ligands. While IgG aggregates and monomeric IgG blocked Fc-dependent chemiluminescence, IgG Fc fragments were stimulatory of this response.
