Beyond Amyloid - Widening the View on Alzheimer's Disease

subject

description

For 25 years, the amyloid cascade hypothesis, based on the finding that mutations in the amyloid precursor protein are closely linked to familial forms of Alzheimer's disease (AD), dominated the research on this disease. Recent failures of clinical anti-amyloidogenic trials, however, substantially support the reasoning (i) that the pathomechanisms that trigger familial AD, namely the generation, aggregation, and deposition of amyloid beta, cannot necessarily be extrapolated to sporadic cases and (ii) that amyloid beta represents a prominent histopathological feature in AD but not its exclusive causative factor. In autumn 2016, the Volkswagen Foundation hosted the Herrenhausen Symposium ‘Beyond Amyloid – Widening the View on Alzheimer's Disease’ in Hannover, Germany, to bring together current knowledge on cellular and molecular processes that contribute to AD pathogenesis independent of or alongside with the amyloid biochemistry. The following mini review series was authored by key speakers at the meeting, and highlights some of the mechanisms potentially involved in AD etiology that provide alternative viewpoints and mechanisms beyond the amyloid cascade hypothesis. This article is part of the series “Beyond Amyloid”.
