Abstract
Aberrant protein folding and subsequent aggregation play a central role in a broad range of diseases that can affect nearly every tissue and organ. In particular, protein aggregation has been implicated in several neurodegenerative and cardiovascular diseases, such as Alzheimer’s disease and cardiac amyloidosis, that are associated with significant morbidity and mortality. Increasing evidence highlights that misfolded protein oligomers exert significant proteotoxicity and result in cell death, serving as a main driver of disease pathogenesis. Autophagy is a natural, precisely regulated process responsible for the sequestration and clearance of misfolded proteins and damaged organelles to counteract the effects of proteotoxicity. Through a variety of mechanisms, autophagic pathways are often impaired in protein aggregation diseases. Moreover, augmenting autophagy has been demonstrated to ameliorate the end organ damage caused by protein aggregates. Therefore, understanding the interactions between protein aggregation and autophagy are crucial to treat proteotoxic neurodegenerative and cardiovascular diseases.
