Diabetes: Gene therapy for rats and mice

Delivery of an insulin-encoding gene into diabetic rats and mice has helped them to regulate their blood glucose levels. But there are still obstacles to overcome before this approach can be used in humans.

Type I diabetes is an autoimmune disease that begins in childhood or early adulthood, and eventually causes complete destruction of the insulin-secreting beta-cells in the pancreas1. The upshot is that patients with type I diabetes produce absolutely no insulin.
