An Approach to Interfering in Mitochondrially Mediated Cell Death due to Amyloid- β in Alzheimer ' s Disease

In this study, we examine multiple mitochondrial pathways of amyloid toxicity in neuronal and cerebral endothelial cells (ECs), and evaluate CAIs methazolamide (MTZ) and, for the first time, its analog acetazolamide (ATZ), on specific Aβ-mediated pathways of mitochondrial dysfunction and apoptotic cell death. The CAIs selectively inhibited mitochondrial dysfunction pathways induced by Aβ, without affecting metabolic function. Due to the long-term use of MTZ and ATZ in chronic conditions, the efficacy and the safety of their systemic administration have been widely assessed, making clinical trials for CAIs in AD a concrete possibility. Our novel findings on the mitochondrial effects of MTZ and ATZ against neuronal and vascular amyloid toxicity justify the selection of these drugs as a therapeutic strategy for AD and cerebral amyloid angiopathy.
