What is the Origin of Exerkines?

The term is a portmanteau combining "exercise" and "cytokines," coined by researchers to classify the newly discovered class of myokines that were specifically released during muscle exertion. This conceptualization emerged from the growing recognition that skeletal muscle is not merely a motor organ but a significant endocrine tissue. The discovery shifted the paradigm of exercise from purely mechanical stress to a powerful hormonal stimulus.

What is the Mechanism of Exerkines?

Muscle contraction initiates a cascade of intracellular events, including changes in calcium concentration and energy state, which trigger the release of various exerkines. These molecules then circulate and bind to specific receptors on target cells in other tissues, mediating pleiotropic effects. For example, myokines like Interleukin-6 (IL-6) and Irisin can influence glucose metabolism, fat oxidation, and neurogenesis, translating the local muscular effort into systemic metabolic and cognitive improvements.

Exerkines

Meaning

Exerkines are a diverse group of biologically active signaling molecules, including peptides, microRNAs, and metabolites, that are released into the circulation from skeletal muscle fibers in response to muscle contraction during physical exercise. These molecules function as endocrine, paracrine, or autocrine mediators, transmitting the physiological benefits of exercise to distant organs such as the liver, adipose tissue, brain, and bone. Clinically, exerkines are a key component of the anti-inflammatory and metabolic benefits of physical activity, acting as a crucial communication link between the musculoskeletal system and systemic health.
