Calorie restriction and calorie-restriction mimetics activate chaperone-mediated autophagy
Overview
Paper Summary
Calorie restriction (CR) and calorie-restriction mimetics (CRMs) activate chaperone-mediated autophagy (CMA), a cellular recycling process. This activation is due to increased stability of LAMP2A, the CMA receptor, at the lysosome membrane, and is required for the protective effects of CRMs against high-carbohydrate diets in mice.

Scientists found that eating less or taking special pills helps your body's tiny cleanup crew work better. This cleaning helps protect your body from unhealthy foods, like too much sugar.
Possible Conflicts of Interest
A.M.C. is a co-founder and scientific advisor for the autophagy program at Life Biosciences, although they state this is not related to the work reported and has not been supported by the company. A.M.C. has also co-authored positioning papers with the reviewers, although they clarify these were opinion pieces and not collaborative research.
Identified Limitations
Rating Explanation
This study provides compelling evidence for the role of CMA in mediating the beneficial effects of calorie restriction and its mimetics. The experiments are well-designed, utilizing both in vitro and in vivo models to demonstrate CMA activation and its dependence on LAMP2A stabilization. The study also establishes the importance of CMA for CRM's protective effects against dietary challenges. While the study is limited by its focus on male rodents and lack of long-term data, the findings are significant and open new avenues for gerotherapeutic interventions.
