Converting Pancreatic α-Cells to β-Like-Cells

There are four main cell types in the islets of Langerhans in the pancreas; α-cells which secrete glucagon, β-cells which secrete insulin, δ-cells which secrete somatostatin, and PP cells which secrete pancreatic polypeptide. Type I diabetes is an autoimmune disease

Potent Inhibitor of Insulin Degrading Enzyme Reported

A new study from a Mayo Clinic-led research team has identified novel, potent inhibitors of insulin degrading enzyme (IDE). Despite an interest in IDE for over 50 years, because of its involvement in insulin catabolism, these are the first potent

New Insights into Adipogenesis

The nuclear receptor, PPARγ, has hitherto been regarded as the master regulator of adipogenesis, without which new adipose tissue cannot be formed. Adipogenesis plays a key role in obesity and associated metabolic diseases such as type II diabetes and the

New Indication for Aldose Reductase Inhibitors?

The physiological role of aldose reductase (AR) is still incompletely understood, although it has long been associated with the pathogenesis of diabetes-associated diseases such as cataract and neuropathy. In the last twenty years a number of AR inhibitors have entered
