Transplanting cadaver pancreatic islets is a promising therapy for Type 1 diabetes, but a reactivated autoimmunity means low graft viability after five years. Research now shows that a protective coating of two biopolymers can delay allograft and autoimmune-mediated rejection in mouse models of T1D.
