Diabetologia, 58(9), 2056-2063 (2015-06-10)
In humans, the rate of beta cell proliferation declines rapidly during the postnatal period and remains low throughout adult life. Recent studies suggest that this may reflect the distribution of cell cycle regulators which, unusually, are located in the cytosolic...

The transplantation of porcine islets of Langerhans to treat type 1 diabetes may provide a solution to the demand for insulin-producing cells. Porcine islets encapsulated in agarose-agarose macrobeads have been shown to function in nonimmunosuppressed xenogeneic models of both streptozotocin-induced...

Injectable, degradation-resistant peptide agonists for the glucagon-like peptide 1 (GLP-1) receptor (GLP-1R), such as exenatide and liraglutide, activate the GLP-1R via a complex orthosteric-binding site and are effective therapeutics for glycemic control in type 2 diabetes. Orally bioavailable orthosteric small-molecule...
