Diabetes induces several complications, including retinopathy and nephropathy. In patients with type 1 diabetes as well as those with type 2 diabetes, pancreatic beta cells have reportedly decreased. Therefore, regeneration therapy of pancreatic beta cells may be very effective for major populations of diabetic patients. We discovered a neuronal network, from the liver, which selectively elicits pancreatic beta cell proliferation (Science 2008, Fig.). In a murine model with insulin-deficient diabetes, stimulation of this network improved diabetes. Thus, building devices which regulate the inter-organ neuronal network may lead to “regenerative therapy” for diabetes which regenerates pancreatic beta cells in the pancreas using patients’ own cells and patients’ own systems. We hope to conduct collaborative research with a willing company for a practical application of this technology.
