mTOR links nutrients, inflammaging and lifespan

Abstract

A study from Ortega-Molina and colleagues uses mouse models with mildly elevated mTOR activity to investigate the stepwise process by which increased nutrient signaling affects healthy aging. These findings show how initial parenchymal damage caused by mTOR activity is followed by secondary myeloid inflammation, a multistage process that culminates in organ deterioration and reduced lifespan.
