abstract：:Calpain activation has been implicated in the pathogenesis of Alzheimer's disease. Okadaic acid, a protein phosphatase-2A inhibitor, has been used in Alzheimer's disease research models to increase tau phosphorylation and induce neuronal death. We previously reported that okadaic acid induced predominant activation of...
