Researchers tested whether psilocybin, a compound from magic mushrooms, could protect pancreatic β-cells (which produce insulin) from damage caused by high glucose and fat levels. Using laboratory cells, they found that psilocybin reduced β-cell death by preventing apoptosis and showed promise in reducing dedifferentiation (when cells lose their specialized functions). However, psilocybin didn’t restore the cells’ ability to respond to glucose by releasing insulin.
