Much like paper must be folded into the correct shape to create an origami sculpture, proteins inside cells must form precise three-dimensional structures before they can function properly.
As prediabetes advances toward diabetes, this delicate process can begin to break down. Misfolded and defective proteins accumulate inside cells, creating stress that can damage the pancreatic cells responsible for producing insulin.
Researchers from Sanford Burnham Prebys Medical Discovery Institute and the University of Michigan reported new details about this process on June 1, 2026, in the Proceedings of the National Academy of Sciences. Their findings reveal how insulin-producing cells coordinate protein folding and what happens when that system falls out of balance. The work suggests that strengthening the cellular machinery responsible for folding proteins could help protect these cells from damage.
Why Insulin-Producing Beta Cells Become Overwhelmed
Beta cells in the pancreas monitor blood sugar levels. When glucose rises, they respond by producing additional insulin, which helps return blood sugar to a normal range.
