Purpose

Type 1 diabetes is caused by an autoimmune destruction of the insulin producing cells of the pancreas. The investigators have discovered the specific autoimmune cells responsible for destroying the insulin-producing cells in an animal model of type 1 diabetes, and the means of destroying those cells.

The investigators are now aiming to use a similar strategy (vaccination with BCG, the vaccine used world-wide to protect against tuberculosis) in human type 1 diabetes to see if the abnormal immune cells can be depleted. This is the first step in trying to cure established type 1 diabetes.
