Blue mussel () water extract ameliorates intestinal immune response in high-fat diet-streptozotocin-induced diabetic mice.

Diabetes mellitus is a metabolic disease characterized by high blood glucose levels or hyperglycemia. Diabetes causes a decrease in immune function in the human body. has been identified as having anti-inflammatory properties and the ability to improve inflammation. Thus, this study aimed to investigate the function of Matsu water extract (MWE) in mediating the regulation of immune responses and dysregulating the intestinal immune system in hyperglycemia mouse models. The mice were treated with MWE for seven weeks. The results showed that treatment with MWE has the ability to decrease triglyceride and total cholesterol concentrations. MWE also increases the interleukin (IL)-10 concentration and natural killer cell activation. It also improves the phagocytic capacity of monocytes in the colon and the proliferative capacity of lymphocytes in the mesentery. Furthermore, MWE also regulates the IL-6 concentration and the ratio of T helper 17 cells to regulatory T cells. Collectively, this extract can improve dyslipidemia, inflammatory responses, and dysregulation of the intestinal immune system. Therefore, water extract can be used as an alternative treatment to reduce diabetes complications.
