The uptake of C-reactive protein (CRP)-pneumococcal C-polysaccharide (CPS) complexes by neutrophils was studied. A specific CRP dependent mechanism of uptake was demonstrated. This promoted CPS (complexed to CRP) clearance which was further enhanced by additional complement activation. Physiological concentrations of low density lipoprotein inhibited entry of complexed CPS into neutrophils but had no effect on entry of CRP alone. Pure human CRP was shown to have no effect on neutrophil chemotaxis and oxidative metabolism.
研究了中性粒细胞对C反应蛋白(CRP)-肺炎球菌C多糖(CPS)复合物的摄取。证实了一种依赖CRP的特异性摄取机制。这促进了(与CRP复合的)CPS的清除,额外的补体激活进一步增强了这种清除。生理浓度的低密度脂蛋白抑制复合CPS进入中性粒细胞,但对单独的CRP进入没有影响。已表明纯人CRP对中性粒细胞趋化性和氧化代谢没有影响。
