作者最近报道,人外周血单核细胞对抗-Rho致敏的人红细胞的免疫吞噬作用,在体外能特异地被某些主要组织相容性复合物的单克隆或多克隆抗体所抑制。这种免疫吞噬的抑制作用,不是由细胞的损伤或麻痹所致,因为颗粒的吞噬作用未受影响。由于免疫球蛋白是从很多人的大量血浆中提取的,可以想象一定含有能引起免疫吞噬抑制(IpI)的 The authors recently reported that immunophagocytosis of human peripheral blood mononuclear cells against -Rho-sensitized human erythrocytes is specifically inhibited by monoclonal or polyclonal antibodies to certain major histocompatibility complex in vitro. The inhibitory effect of this immunophagocytosis is not due to cell damage or paralysis because the phagocytosis of the particles is unaffected. Since immunoglobulins are extracted from a large amount of human plasma, it is conceivable that they must contain IpI
