Adrenocorticotropic hormone can relieve acute inflammation in gout models by inhibiting the polarization of macrophages to M1 type, inhibiting ROS and proinflammatory factor production and protecting mitochondrial function. Adrenocorticotropic hormone can be used for the researches of inflammation, endocrinology, metabolic disease, such as gout and nephrotic syndrome.
