Does Irisin Play a Role in Aging? The Myokine's Complex Influence

First identified in 2012, irisin is an exercise-induced hormone secreted from muscles that has been strongly linked to metabolic health, often mimicking the benefits of physical activity. However, a growing body of evidence from animal studies and human observations suggests that **irisin may play a significant role in aging**, influencing factors from cellular senescence to bone health. This multifaceted myokine appears to counteract age-related declines in various systems, although more research is needed to fully understand its therapeutic potential.
