Hyperphosphorylated tau aggregation and cytotoxicity modulators screen identified prescription drugs linked to Alzheimer's disease and cognitive functions.

ABSTRACT: The neurodegenerative Alzheimer's disease (AD) affects more than 30 million people worldwide. There is thus far no cure or prevention for AD. Aggregation of hyperphosphorylated tau in the brain correlates with the cognitive decline of patients of AD and other neurodegenerative tauopathies. Intracerebral injection of tau aggregates isolated from tauopathy brains causes similar pathology in the recipient mice, demonstrating the pathogenic role of abnormally phosphorylated tau. Compounds controlling the aggregation of hyperphosphorylated tau therefore are probable modulators for the disease. Here we report the use of recombinant hyperphosphorylated tau (p-tau) to identify potential tauopathy therapeutics and risk factors. Hyperphosphorylation renders tau prone to aggregate and to impair cell
