α-Melanocyte-stimulating hormone (α-MSH) is a peptide hormone that plays a crucial role in pigmentation, inflammation, and appetite regulation. It is produced by the pituitary gland and is derived from proopiomelanocortin (POMC), a precursor protein.
Key points:
-
Pigmentation: α-MSH stimulates melanocytes, the pigment-producing cells in the skin, hair, and eyes. It promotes the production of melanin, the pigment responsible for skin, hair, and eye color.
-
Immunomodulation: α-MSH can modulate immune cell activity and can reduce inflammation in various tissues.
-
Appetite Regulation: α-MSH interacts with receptors in the hypothalamus, a region of the brain involved in appetite regulation. It has anorexigenic effects, meaning it can suppress appetite.
-
Thermoregulation: α-MSH plays a role in thermoregulation by affecting heat dissipation and energy balance in the body.
-
Neuroprotection: Some studies suggest that α-MSH may have neuroprotective effects and could be explored for potential therapeutic applications in neurological disorders.
-
Sexual Function: There is evidence to suggest that α-MSH may influence sexual behavior and reproductive functions.
