Core Tip

Core Tip: Obesity is closely associated with the occurrence and development of insulin resistance and type 2 diabetes mellitus (T2DM). Previous studies have demonstrated the important role of immune cell infiltration and inflammatory response in obesity-related T2DM. This review presents immune responses in the gut with respect to metabolic challenges. We also highlight the effects of immune attacks and proinflammatory shifts on insulin-secreting and targeting organs.
