  • Title: [Influence of Ca2+ ions on UV-induced damage to mice peritoneal macrophage plasma membranes].
    Author: Pirutin SK, Turovetskiĭ VB, Pirutina OV, Kudriashov IuB.
    Journal: Radiats Biol Radioecol; 2004; 44(4):438-41. PubMed ID: 15455674.
    Abstract:
    It was shown that UV-irradiation caused damage to mice peritoneal macrophage plasma membranes. A decrease in extracellular Ca2+ leads to a decrease of the damaging effect. An increase in extracellular Ca2+ or adding of calcium ionophore A23187 to the medium is accompanied by an increase in a number of damaged cells. These data allow us to suppose that modification of the damaging effect of UV-irradiation by Ca2+ ions can be bound with changing of electric stability of membrane lipid matrix.
