摘要

The JAK/STAT signaling pathway serves as an important downstream mediator for a variety of cytokines, hormones, and growth factors. Emerging data show that this pathway is dysregulated in metabolic diseases including obesity and type 2 diabetes. With the use of tissue-specific knockout mice, JAK/STAT signaling in the peripheral metabolic organs has been shown to regulate a multitude of metabolic processes including, but not limited to, glucose tolerance, insulin sensitivity, energy expenditure, and adiposity. JAK/STAT signaling within immune cells crucially regulates inflammation that is associated with metabolic abnormalities including insulin resistance and obesity. The JAK/STAT signaling pathway is a promising therapeutic target for the treatment of obesity, metabolic syndrome, and diabetes. The Janus kinase (JAK)/signal transducer and activator of transcription (STAT) pathway is crucial for transducing signals from a variety of metabolically relevant hormones and cytokines including growth hormone, leptin, erythropoietin, IL4, IL6 and IFNγ. A growing body of evidence suggests that this pathway is dysregulated in the context of obesity and metabolic disease. Recent development of animal models has been instrumental in identifying the role of JAK/STAT signaling in the peripheral metabolic organs including adipose, liver, muscle, pancreas, and the immune system. In this review we summarize current knowledge about the function of JAK/STAT proteins in the regulation of metabolism, and highlight new potential therapeutic targets for the treatment of obesity and diabetes.

Activating JAK2 mutations are found in this condition. a strain of mice that develop spontaneous autoimmune pancreatic β-cell destruction that is used as a model of type 1 diabetes. a transcription factor necessary for pancreatic development. a group of transcription factors that regulate genes important for development and metabolism. a hormone secreted by the pituitary gland that promotes lactation. DNA sequence that regulates the expression of insulin in rats and mice. intracellular transcription factors that are primarily activated by membrane receptor-associated Janus kinases (JAKs). the abnormal retention of lipids within a cell. a type of immune cell that plays a role in the adaptive immune system. a transport protein, synthesized by the liver, that carries the thyroid hormone thyroxine and retinol-binding protein. a mitochondrial inner membrane protein that is responsible for converting energy to heat instead of ATP. the major site of energy storage in the form of fat, contributes to endocrine regulation of energy balance.
