Fat Tissue Is a Longevity Control Center—And It Could Change How We Treat Aging
New research in PNAS reveals that adipose tissue regulates lifespan through a microRNA processing mechanism independent of previously known aging pathways, positioning fat tissue as a "longevity hub" that controls insulin signaling and glucose homeostasis across the body. If this mechanism translates to humans, it could enable a new class of aging drugs that work like insulin sensitizers without the growth-suppressing side effects that plague current interventions.
