melanocyte-stimulating hormone (MSH)

Melanocyte-stimulating hormone (MSH) is a chemical produced by the brain and pituitary gland that helps regulate skin pigmentation, appetite, and energy balance. It stimulates cells called melanocytes in the skin to produce melanin, the pigment responsible for skin and hair color, influencing tanning and pigmentation changes. Additionally, MSH plays roles in controlling hunger and mood. Its functions are important for maintaining normal pigmentation patterns and energy homeostasis, and it can also have anti-inflammatory effects in the body.
