irisin

Definition

A specific signaling protein (myokine) released by skeletal muscles during exercise that acts as an exerkine to support brain health.

Etymology

The name is derived from Iris, the Greek goddess of the rainbow and messenger of the gods, combined with the suffix -in used for proteins. It was named this way because the protein acts as a messenger sent from muscles to other tissues.

In the news

Irisin is listed as one of the key exerkines produced by muscles during exercise that helps protect neurons in Parkinson's disease patients. It serves as a molecular messenger that facilitates the beneficial crosstalk between active muscles and the brain.
