Protein that repels immune cells protects transplanted pancreatic islets from rejection

A possible solution to limitations that have kept pancreatic islet transplantation from meeting its promise as a cure for type 1 diabetes has been developed by researchers. They report that encapsulating insulin-producing islets in gel capsules infused with a protein that repels key immune cells protected islets from attack by the recipient's immune system without the need for immunosuppressive drugs, restoring long-term blood sugar control in mouse models.
