[摘要]：Saturated fatty acids, acting as ligands for toll-like receptor 4 (TLR4), induce inflammation and mediate the development of insulin resistance. Myeloid differentiation factor 88 (MyD88) is an adaptor protein for TLR4. Previously, we found MyD88-deificient mice fed a high-fat diet (HFD) exhibited a severe diabetic phenotype. Stearoyl-CoA Desaturase 1 (SCD1) is the rate-limiting enzyme in the biosynthesis of monounsaturated fatty acids and known as a risk factor of diabetes. In the present study, we found SCD1 was dramatically increased in HFD-fed MyD88-deficient mice liver. This finding showed the novel linkage between MyD88 and SCD1 in the development of diabetes mellitus. (C) 2012 Elsevier B.V. All rights reserved. |
