Two different antibodies to copper, zinc-superoxide dismutase and one antibody to manganese-superoxide dismutase were evaluated by immunoblotting of homogenates of mind before make use of in immunohistochemistry. intensities and distributions of the two types of superoxide dismutase immunoreactivities were different in comparison with handles. Copper, zinc-superoxide dismutase was enriched in pyramidal neurons going through degeneration, whereas manganese-superoxide dismutase RAB11FIP4 was even more enriched in reactive astrocytes than in neurons. In senile plaques, copper, zinc-superoxide dismutase-positive globular buildings were encircled by astrocytes enriched in manganese-superoxide dismutase highly. By dual label immunohistochemistry, some pyramidal neurons coexpressed superoxide tau and dismutases, and some copper, zinc-superoxide dismutase-positive buildings in senile plaques colocalized with tau. Amyloid cores, diffuse plaques, and microglia showed colocalization with superoxide dismutase-positive buildings scarcely. The observed adjustments in the mobile localization of superoxide dismutases in neocortex and hippocampus Nifenalol HCl in situations of Alzheimer’s disease and Down’s symptoms support a job for oxidative damage in neuronal degeneration and senile plaque formation. The differential localization of copper, Nifenalol HCl zinc-superoxide dismutase and manganese-superoxide dismutase in cerebral sites of degeneration shows that mobile replies to oxidative tension is normally antioxidant enzyme particular and cell type particular and these two types of superoxide dismutase may possess different features in antioxidant systems.
