Diabetes mellitus type 1 According to the current definition, two fasting glucose measurements above 126 mg/dl (7.0 mmol/l) is considered diagnostic for diabetes mellitus. In type 1, pancreatic beta cells in the islets of Langerhans are destroyed, decreasing endogenous insulin production. This distinguishes type 1's origin from type 2. Type 2 diabetes is characterized by insulin resistance, while type 1 diabetes is characterized by insulin deficiency, generally without insulin resistance. Another hallmark of type 1 diabetes is islet autoreactivity, which is generally measured by the presence of autoantibodies directed towards the beta cells. The appearance of diabetes-related autoantibodies has been shown to be able
Epigenetics of diabetes Type 2 energy metabolism and inflammation. SIRT1 overexpression or activation by resveratrol could improve insulin resistance and SIRT1 activators are being developed for diabetes treatment. The role of other HDACs and the potential use of HDAC inhibitors in diabetes is not very clear. Other treatments look towards an anti-inflammatory agent and HAT inhibitor, curcumin, which in trials ameliorated high glucose-induced inflammatory gene expression and histone acetylation at their promoters as well as changes in HAT and HDAC activities in human monocytes. Metabolic memory is the phenomenon of diabetic vascular stresses persisting after glucose normalization in diabetic patients because of early an glycemic
