Działania biochem./fizjol.

Ceruloplasmin (Cp), the principal carrier of copper in plasma, is thought to be involved in oxidative modification of lipoproteins and participate in the acute phase reaction to stress. Cp is an effective antioxidant for a variety of radicals and has a potent peroxidase activity to decompose hydrogen peroxide in the presence of reduced glutathione. It inhibits the peroxidase activity of myeloperoxidase in a concentration-dependent manner and shows selective binding to myeloperoxidase in vitro. This suggests that ceruloplasmin may participate in the clearance and inactivation of myeloperoxidase in vivo. At physiological (micromolar) concentrations it was found to inhibit relaxation of rabbit aorta induced by endothelium-dependent agonists like acetylcholine or ADP. However, it was found ineffective toward vasodilation due to direct stimulation of smooth muscle cells by nitroglycerin. Cp plays an essential role in iron homeostasis, regulating the efflux of iron from macrophages and the oxidation of Fe2+ to Fe3+. Cp deficiency leads to neurodegenerative disorders, possibly by starving neurons of iron.

In pancreatic islets, free radical formation produced upon exposure to proinflammatory cytokines mediates β cell destruction, which ultimately leads to type 1 diabetes (T1D). In this study, we examined whether laccase, a family of the blue copper protein, can be
