Effect of the 1-methyl-4-phenylpyridinium ion on phosphorylation of tyrosine hydroxylase in rat pheochromocytoma PC12h cells.

abstract：:Peripheral inflammation induced by intraperitoneal (i.p.) injection of Lipopolysaccharide (LPS) is known to cause functional impairments in the brain affecting memory and learning. One of mechanisms may be the interference with neurotrophin (NT) expression and function. In the current study we administered a single, h...
