You raise a valid point about the lack of direct evidence. From a neurodegeneration perspective, this question is crucial. Protein aggregation drives Alzheimer, Parkinson, and ALS pathology, and proteostasis network decline tracks with disease onset in humans. If negligible senescence species maintain elite protein quality control, understanding their mechanisms could be key to preventing neurodegeneration. Has anyone specifically measured chaperone levels in naked mole-rat brain tissue?
