红细胞是人体血液中最多的一种血细胞,在血液的气体运输中担负着极其重要的生理功能,这是大家所熟知的。近年来,随着免疫学技术的研究不断深入,进一步揭示了红细胞的另一种功能——即红细胞免疫粘附(RCIA)作用。红细胞的免疫粘附作用能清除血循环中的免疫复合物,阻止免疫复合物在机体组织中的沉积。本文就这一方面作一简单介绍:一、红细胞免疫粘附的一般生理红细胞免疫粘附是由于灵长类和非灵长类的红细胞表面具有补体C_(3b)受体,该受体是一种存在于多种细胞膜上的糖蛋白,分子量为205000。它的主要免疫学功能是增强机体对免疫复合物的
It is well known that erythrocytes are the most abundant type of blood cells in the body’s bloodstream and carry an extremely important physiological function in the transport of blood gases. In recent years, with the deepening of immunological technology research, further revealed another function of red blood cells - that is, the role of erythrocyte immune adhesion (RCIA). Immune adherence of erythrocytes clears the immune complexes in the blood circulation and prevents the deposition of immune complexes in the tissues of the body. In this paper, a brief introduction on this aspect: First, the erythrocyte immune adhesion of the general physiological erythrocyte immune adhesion is due to primate and non-primate red blood cell surface has a complement C_ (3b) receptor, the receptor is a A variety of cell membranes exist in the glycoprotein, a molecular weight of 205000. Its main immunological function is to enhance the body’s immune complex
