A hormone can access the brain by 'hitchhiking' on extracellular vesicles, researchers discover

Researchers at Touro University Nevada have discovered that tiny particles in the blood, called extracellular vesicles (EVs), are a major player in how a group of hormones are shuttled through the body. Physical exercise can stimulate this process.

Exercise Supercharges Hormone Transport to the Brain

Physical exercise triggers extracellular vesicles (EVs)—tiny particles in the blood—to act as temporary transport shuttles for key hormone precursors. During vigorous exercise, levels of the hormone precursor POMC attaching to EVs increase fourfold, suggesting a newly uncovered mechanism for how stress, energy balance, and mood may shift after movement.
