Phosphatase activity toward abnormally phosphorylated tau: decrease in Alzheimer disease brain.

abstract：:Cl(-)-ATPase in the CNS is a candidate for an outwardly directed neuronal Cl(-) transporter requiring phosphatidylinositol-4-phosphate (PI4P) for its optimal activity. To test its pathophysiological changes in a phosphatidylinositol (PI) metabolism disorder, the effects of neurotoxic factors in Alzheimer's disease (AD...
