PG - 108-16 AB - The role of monocyte chemoattractant protein-1 (MCP-1) in the recruitment of blood-derived monocytes in a model of zymosan peritoneal inflammation was investigated. After zymosan injection (1 mg) a rapid influx of polymorphonuclear leukocytes (PMN) and monocytes into the peritoneal cavity associated with mouse MCP-1 (JE) gene activation and protein secretion in the exudates occurred. MCP-1 production (maximal at 4 h) preceded the accumulation of monocytes (F4/80-positive cells, maximally recovered between 16 and 24 h). Treatment of mice with a single injection of anti-mouse MCP-1 antibody inhibited 16-h monocyte accumulation by approximately 40%, however, a significant decrease in the number of PMN was also measured. Finally, intraperitoneal injection of murine recombinant MCP-1 (1 microg) produced a selective accumulation of monocytes (F4/80-positive cells) into the peritoneal cavity. In conclusion, we show the novel existence of a strict relationship between MCP-1 production and leukocyte accumulation in this model of acute inflammation.
