New research for canine, human Type 1 diabetes holds promiseAugust 24, 2018Reversing Type 1 diabetes in dogs and humans without the use of daily insulin injections or pumps may become a reality, thanks to a collaboration between Purdue University and the Indiana University School of Medicine. In a preclinical study, researchers developed a mixture of collagen and pancreatic cells and engineered a delivery method that successfully reversed Type 1 diabetes within 24 hours and maintained insulin independence for 90 days. A clinical study in dogs with naturally occurring Type 1 diabetes in collaboration with Purdue's College of Veterinary Medicine is next. "We plan to account for differences from mouse to human by helping dogs first," said Clarissa Hernandez Stephens, first author on the work and a graduate researcher at Purdue's Weldon School of Biomedical Engineering. "This way, the dogs can inform us on how well the treatment might work in humans." Because diabetes in dogs and humans occurs the same, both potentially could benefit from the same cure: A new set of pancreatic cells to replace islets (clusters of cells) that aren't releasing insulin to monitor blood glucose levels. Islet transplantation isn't new, and it poses challenges: It requires multiple donors, it's invasive, and large numbers of transplanted …
