To study the role of the spleen in the elimination of immune complexes we examined mononuclear phagocyte system function in eight healthy controls and eight splenectomized patients, with soluble 123I-labelled aggregates of human immunoglobulin G (AIgG). No differences were found between the two groups in elimination and degradation of AIgG. The loss of splenic function was compensated for by increased uptake of AIgG by the liver. With the dose of 123I-AIgG used in this study (10 micrograms/kg body weight), significant generation of C3a was observed. No correlation was found between erythrocyte CR1 number and the fraction of aggregates that bound to erythrocytes.
为研究脾脏在清除免疫复合物中的作用,我们用可溶性123I标记的人免疫球蛋白G聚合体(AIgG)检测了8名健康对照者和8名脾切除患者的单核吞噬细胞系统功能。两组在AIgG的清除和降解方面未发现差异。脾脏功能的丧失通过肝脏对AIgG摄取的增加得到了补偿。在本研究使用的123I - AIgG剂量(10微克/千克体重)下,观察到了C3a的显著生成。红细胞CR1数量与结合到红细胞上的聚合体比例之间未发现相关性。
