[Regulation of mechanical stability of erythrocytes by serum immunoglobulins]
Autologic plasma protects human erythrocytes from hemolysis induced by their suction through glass microfiber filters. The protective effect is related to the protein fraction with molecular mass above 100 kD and reproduced by gamma-globulin. The action of proteins is abolished after heating the erythrocytes above 45 degrees C as well as in the presence of galactose and ribose but not glucose, mannose and lactose. It is suggested that an increase in mechanical stability of erythrocytes is caused by interaction of immunoglobulins with glycoproteid and glycolipid membrane receptors and mediated by the changes of structural state of the cytoskeleton.
