All tested ALS IgGs (compared to control IgG) induced oxidative stress (rise in nitric oxide and the index of lipid peroxidation) followed by release of TNF-α and higher antioxidative defense (elevation of Mn- and CuZn-superoxide dismutase, catalase, and glutathione reductase with a decrease of glutathione peroxidase and glutathione) after 24 h treatment.
We determined activity of the following ADEs: copper-zinc superoxide dismutase (CuZn SOD), catalase (CAT), glutathione peroxidase (GSH-Px) and glutathione reductase (GR) in erythrocytes from sporadic ALS patients [SALS (-/+)], familial ALS patients with the Leu144Phe mutation in the SOD1 gene [FALS (+/+)], asymptomatic carriers with the Leu144Phe mutation in the SOD1 gene (+/-), and control subjects (-/-).
