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 was seen in an experiment when a high glucose treatment of cultured monocytes increased recruitment of the HATs CREB-binding protein (CPB) and PCAF, leading to increased histone lysine acetylation at the cyclooxygenase-2 (COX-2) and TNF-inflammatory gene promoters. This led to a corresponding increase in gene expression, which was similar to the increased histone lysine acetylation at these gene promoters in type 1 diabetes and type 2 diabetes patients compared to healthy control volunteers. There are several factors that put people at higher risk of contracting Type 2 diabetes. Among these are obesity, lack of exercise, and aging. But, not everyone
