The effect of substrate-bound immunoglobulin on neutrophil migration was examined. Immunoglobulin aggregates bound to micropore membranes inhibited the neutrophil response to a chemotactic stimulus. This inhibition was reversed by the presence of aggregates in suspension suggesting competition between substrate-bound and free aggregates for neutrophil surface binding sites. The immobilization of neutrophils by substrate-bound aggregated immunoglobulin suggests a mechanism for the accumulation of neutrophils at sites of immune complex deposition and tissue-bound antibodies in vivo.
研究了底物结合免疫球蛋白对中性粒细胞迁移的影响。结合在微孔膜上的免疫球蛋白聚集体抑制了中性粒细胞对趋化刺激的反应。悬浮液中聚集体的存在可逆转这种抑制作用,这表明底物结合聚集体与游离聚集体之间存在对中性粒细胞表面结合位点的竞争。底物结合的聚集免疫球蛋白使中性粒细胞固定,这提示了中性粒细胞在体内免疫复合物沉积部位和组织结合抗体部位积聚的一种机制。
