Review: mTOR as a context-dependent hub linking aging hallmarks and geroprotective interventions
This review describes mTOR as a dynamic signaling hub coordinating nutrient sensing, metabolism and stress responses. It reports causal evidence for lifespan regulation in model organisms, while human data remain mainly associative. Interventions such as autophagy activation, dietary changes, physical activity and senotherapeutics partly converge on mTOR but also use parallel pathways. [1]

mTOR as hub for nutrient sensing and stress
The review presents a three-section framework in which the mechanistic target of rapamycin (mTOR) pathway acts as a dynamic signaling hub. It integrates nutrient sensing, metabolic adaptation and cellular stress responses, and coordinates multiple biological processes underlying aging. Two complexes, mTORC1 and mTORC2, regulate distinct yet complementary aspects of metabolism, protein balance (proteostasis), autophagy, stress adaptation and tissue homeostasis.

Causal evidence in models, associative human data
According to the review, genetic, experimental and translational studies support a causal role for mTOR signaling in lifespan regulation in model organisms. Human data, by contrast, remain predominantly associative, though biologically consistent. The authors therefore do not claim that modulating mTOR extends human lifespan; they describe it as a context-dependent signaling hub whose precise, tissue-specific modulation may promote healthy aging and support future geroscience-based interventions.

Interventions converge only partly on mTOR
The review lists major geroprotective interventions: autophagy activation, dietary interventions, physical activity and senotherapeutics. These partly converge on mTOR signaling but also engage parallel pathways. This adaptive regulation is described as restoring anabolic-catabolic balance, enhancing stress resilience and improving metabolic flexibility. The authors conclude that mTOR links multiple hallmarks of aging and diverse geroprotective interventions, and should be viewed not as a single therapeutic target but as a context-dependent hub.

How to interpret this
This is an abstract of a review; the full text was not reviewed. The causal lifespan evidence comes from model organisms, and human data are described as predominantly associative. The abstract reports no specific interventions, doses, effect sizes or trial results, and the proposed framework is not a validated therapy.
Based on the study abstract; the full paper, tables and supplementary data were not reviewed.
