Outline of Final Research Achievements |
We previously reported a liver-brain-pancreas neuronal relay to play an important role in promoting pancreatic β cell proliferation. Here, we elucidated anatomical and biochemical mechanisms of the neuronal signals within the pancreas. First, the tissue clearing method, CUBIC, revealed a major part of parasympathetic ganglia to be located in the vicinity of pancreatic islets. In addition, ex vivo analyses showed that combined stimulation with several neurotransmitters released by vagal nerves enabled β cells to be efficiently proliferated. This neuronal signal-mediated mechanism, elucidated by this research program, holds potential for developing novel approaches to regenerating pancreatic β cells.
