Alpha-melanocyte-stimulating hormone (α-MSH) is a neuropeptide with immunomodulatory properties that is produced by post-translational processing of proproiomelanocortin (POMC). α-MSH binds to the MC1R receptor on melanocytes to stimulate melanin secretion, promote the formation of melanocyte dendrites, and protect melanocytes. α-MSH has an effective anti-inflammatory effect on immune cells. Moreover, α-MSH was shown to inhibit IFN-γ production in antigen-stimulated T cells[1-3].α-MSH- stimulates(1 µM; 72h) melanin production in B16 melanoma cells[4].α-MSH(0-10 ng/mL; 5-10min) enhances the role of protective responses under stress conditions such as UVR by increasing melanin production and reducing mitochondria-mediated apoptosis[5]. α-MSH(100 nM; 48 h) increased tyrosinase activity and melanin content by 56.5% and 61.7%, respectively, and α-MSH changed the level of metabolites in melanoma cells[6].
α-MSH (1mg / kg; i.v;12 h) can increase bacterial load in middle cerebral artery occlusion (MCAO) mice[7]. α-MSH(500 nM ; i.p;0-6 h) promotes fatty acid oxidation in WAT and BAT[8].

α -黑色素细胞刺激激素(α-MSH)是一种具有免疫调节特性的神经肽,由原黑素皮质素(POMC)翻译后加工产生。α-MSH结合黑素细胞上的MC1R受体,刺激黑色素分泌,促进黑素细胞树突的形成,起到保护黑素细胞的作用。α-MSH对免疫细胞具有有效的抗炎作用。此外,α-MSH被证明可以抑制抗原刺激T细胞中IFN-γ的产生[1-3]。
α-MSH-刺激(1 µM; 72h)B16黑色素瘤细胞的黑色素生成[4]。α-MSH(0-10 ng/mL; 5-10min)通过增加黑色素生成和减少线粒体介导的细胞凋亡来增强应激条件下(如UVR)保护反应的作用[5]。α-MSH(100 nM; 48 h)使酪氨酸酶活性和黑色素含量分别提高了56.5%和61.7%,α-MSH改变了黑色素瘤细胞代谢产物的水平[6]。
α-MSH (1mg / kg; i.v;12 h)可增加MCAO小鼠细菌负荷[7]。α-MSH(500 nM ; i.p;0-6 h)促进WAT和BAT的脂肪酸氧化[8]。
