研究问题
Increasing lipophilicity alone does not ensure localization to a specific organelle.；Robust evidence should include organelle fractionation, live-cell imaging, controls lacking the localization moiety, compartment-specific target-occupancy measurements, and quantitative pharmacodynamics ( , ).

核心结论
Genetic screens further show that different degraders share resistance genes associated with the ubiquitin system and drug efflux, while also exhibiting E3- and target-specific resistance mechanisms ( – ).；Trivalent PROTACs can enhance complex stability through increased affinity and cooperativity, although their larger molecular size may impair permeability and pharmacokinetic properties ( , ).；In mice injected with preformed fibrils, oral ATC161 reduced α-synuclein aggregation and spread across brain regions, attenuated glial responses, and improved motor phenotypes, providing in vivo evidence for aggregation-state-selective autophagic degradation…；It reduced insoluble α-synuclein in a p62- and autophagy–lysosome-dependent manner, with a DC 50 of approximately 100 nmol/L, while exerting little effect on soluble monomers ( ).
局限
These parameters should be interpreted alongside cellular DC 50 , D max , degradation kinetics, hook-effect behavior, proteome-wide selectivity, and intracellular free compound concentration ( , , , ).；A reduction in cell-surface protein alone does not establish clinical superiority, and persistent clearance in normal tissues and immune cells may increase immune-related toxicity ( , , ).

本文核心结论来自动物模型或体外细胞学，属临床前证据，不能外推至人体。「延长健康寿命」「改善功能」等表述在小鼠中的意义，与人类临床结局之间仍有距离。
