Insulin Production Occurs Beyond the Pancreas

Recent research reveals that the brain produces insulin in multiple regions and cell types, challenging the long-held belief that insulin in the brain solely originates from the pancreas. Brain insulin may play roles in regulating growth, appetite, and possibly protecting against age-related cognitive decline, but its functions and implications are still being studied. This discovery could lead to updates in educational content and new approaches to neurological diseases like Alzheimer's.
