Automatic summary · not editorially reviewedA review published in Aging describes mTOR as a dynamic signaling hub that coordinates nutrient sensing, metabolism and stress responses in aging. In model organisms evidence supports a causal role in lifespan regulation; human data remain mostly associative. Interventions such as autophagy activation, dietary changes, physical activity and senotherapeutics partly converge on mTOR. [1]
The review presents a three-section framework in which mTOR acts as a dynamic signaling hub coordinating multiple biological processes underlying aging. [1]
Evidence from genetic, experimental and translational studies supports a causal role for mTOR signaling in lifespan regulation in model organisms. [1]
Human data remain predominantly associative but biologically consistent, and interventions partly converge on mTOR while also engaging parallel pathways. [1]
Review asks how mTOR links aging and interventions
This is a review published in the journal Aging on September 19, 2026, in Volume 18, by Natalia Bobok. It asks how the mechanistic target of rapamycin (mTOR) pathway integrates processes involved in aging and longevity, such as nutrient sensing, metabolic adaptation and cellular stress responses. The description presents a three-section framework in which mTOR acts as a dynamic signaling hub coordinating several biological processes underlying aging. [1]
Evidence compared: model organisms versus human data
According to the description, the review draws on genetic, experimental and translational studies. It reports that this evidence supports a causal role for mTOR signaling in lifespan regulation in model organisms, whereas human data remain predominantly associative but biologically consistent. The review also distinguishes mTOR complex 1 (mTORC1) and mTOR complex 2 (mTORC2), which regulate distinct yet complementary aspects of cellular metabolism, proteostasis, autophagy, stress adaptation and tissue homeostasis. [1]
Interventions partly converge on mTOR, not one target
The description says major geroprotective interventions — autophagy activation, dietary interventions, physical activity and senotherapeutics — 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 review concludes that mTOR is an important integrative node linking multiple hallmarks of aging, but should be viewed as a context-dependent signaling hub rather than a single therapeutic target, with precise, tissue-specific modulation possibly supporting healthy aging. These are the review's interpretations; the description gives no effect sizes, and human benefit is not established. [1]
