AMYLOID-INDUCED MODIFICATION OF HUMAN ERYTHROCYTE MEMBRANES. INFLUENCE OF ANTIOXIDANTS
Abstract
We studied the antioxidant defense enzyme activity in amyloid- modified human erythrocytes in vitro, and the influence of antioxidants on the amyloid-induced modification of erythrocyte membranes. It was shown that a combined action of amyloid structures of lysozyme and tocopherol or quercetin on human erythrocytes in vitro enhances membrane lipids microviscosity changes, but the activation of peroxidation process wasn’t detected. Most likely it happens because a total antioxidant activity of all antioxidant defense enzymes in human erythrocytes in vitro does not change under the influence of amyloidoligomers. The activity of glutathione peroxidase decreases while the catalase activity increases and the superoxide dismutase activity doesn’t change as compared to control.
