研究问题
IDPs exist along a spectrum, ranging from proteins containing localized intrinsically disordered regions to those that remain largely disordered throughout their entire sequence [, ].；However, these same structural properties also predispose them to aberrant conformational transitions and aggregation [, ].

核心结论
Alzheimer’s disease (AD), frontotemporal dementia (FTD), and Parkinson’s disease (PD) are neurodegenerative disorders characterized by cognitive, behavioral, and/or motor deficits.；Key contributors to toxic IDP accumulation include impaired autophagosome biogenesis, defective lysosomal acidification, and disrupted autophagic flux, collectively leading to impaired proteostatic clearance and neuronal death [, ].；Emerging evidence suggests that aberrant processing of amyloid precursor protein (APP) and tau can disrupt V-ATPase function, leading to impaired lysosomal acidification and reduced degradative capacity. ‖ 结论：Ultimately, such insights will accelerate the development of personalized therapeutic strategies tailored to lysosomal perturbations and alterations underlying specific IDP-driven neurodegenerative pathologies.
局限
Despite their clinical heterogeneity, they converge on a common molecular pathology: the misfolding and aggregation of intrinsically disordered proteins (IDPs).；Structural heterogeneity, often referred to as amyloid polymorphism, arises from differences in β-strand orientation, packing, and protofilament organization, and is thought to influence aggregation kinetics, toxicity, and disease progression in neurodegenerative disorders [].；However, because many studies do not directly resolve the conformational state of the interacting tau species, these distinctions should be interpreted cautiously. αSyn is a 140-amino-acid protein composed of three functionally distinct domains: an N-terminal a
