The AIM2 inflammasome plays important proinflammation role in many diseases, and can induce pyroptotic cell death. It has also been closely linked to the development and progression of metabolic diseases and can be activated in obesity, diabetes, nonalcoholic fatty liver disease, and atherosclerosis. In this article, we mainly review the role of AIM2 in glucose metabolism, especially in obesity-related disorders of glucose and lipid metabolism, and provide insights to better understand the role of AIM2 in the pathogenesis, and clinical treatment of metabolic disease.Keywords: AIM2, obesity, metabolic diseases, diabetes, glucose metabolism disorders
