Description

? Melanocyte-stimulating hormone (?-MSH) is an endogenous POMC-derived peptide in the pituitary involved in energy homeostasis and melanin production that activates melanocortin receptors. ?-MSH exhibits anti-inflammatory, neuroprotective, cognition enhancing, anxiolytic, and antioxidative activities. In vivo, ?-MSH decreases the intensity of acetaminophen-induced liver lesions. In animal models of Alzheimer?s disease, ?-MSH prevents loss of GABAergic neurons, decreases anxiety levels, and improves spatial memory. ?-MSH also decrease apoptosis and oxidative stress in diabetic retinas by inhibiting upregulation of Foxo4 induced by glucose.
