Tau degradation in Alzheimer's disease: Mechanisms and therapeutic opportunities.

ABSTRACT: In Alzheimer's disease (AD), tau undergoes abnormal post-translational modifications and aggregations. Impaired intracellular degradation pathways further exacerbate the accumulation of pathological tau. A new strategy - targeted protein degradation - recently emerged as a modality in drug discovery where bifunctional molecules bring the target protein close to the degradation machinery to promote clearance. Since 2016, this strategy has been applied to tau pathologies and attracted broad interest in academia and the pharmaceutical industry. However, a systematic review of recent studies on tau degradation mechanisms is lacking. Here we review tau degradation mechanisms (the ubiquitin-proteasome system and the autophagy-lysosome pathway), their dysfunction in AD, and tau-targeted degraders
