The effects of ingestion of soluble immune complexes upon macrophage phagocytic function was studied. Ingestion of immune complexes severely impaired the macrophage's ability to ingest IgG-coated particles but did not alter its ability to interact with particles by means other than its Fc receptors. Treatment of macrophages that had ingested immune complexes with supernates containing the previously described lymphokine that augments macrophage complement receptor function failed to enhance the cells' interaction with either IgG-coated erythrocytes or zymosan particles but markedly enhanced their ability to phagocytize via their complement receptors. The possible significance of these findings in immunologically mediated inflammation is discussed.
研究了摄入可溶性免疫复合物对巨噬细胞吞噬功能的影响。摄入免疫复合物严重损害了巨噬细胞摄取IgG包被颗粒的能力,但并未改变其通过Fc受体以外的方式与颗粒相互作用的能力。用含有上述增强巨噬细胞补体受体功能的淋巴因子的上清液处理已摄入免疫复合物的巨噬细胞,未能增强细胞与IgG包被红细胞或酵母聚糖颗粒的相互作用,但显著增强了它们通过补体受体进行吞噬的能力。讨论了这些发现在免疫介导炎症中的可能意义。
