Abstract

Importance of the field: Type 1 diabetes is a common and very serious disease. There has been very active research going on for a long time aiming at preservation of the residual insulin secretion by some kind of intervention to stop the destructive autoimmune process. This review covers a new type of immune intervention using auto-antigen treatment.

Areas covered in this review: Immune interventions in type 1 diabetes have been tried during the last 30 years, this review mentions some of them, but the main topic is the use of the auto-antigen glutamic acid decarboxylase (GAD) to create tolerance to stop the autoimmune process. The clinical trials have been performed during the last 15 years and are all covered.

What the reader will gain: This review will give the reader a picture of the research behind treatment with GAD as an immune intervention in type 1 diabetes.

Take home message: The key finding so far is that treatment with Diamyd® has not only been shown to preserve residual beta cell function in type 1 diabetes, but this treatment may be the proof in humans of a new concept of treating and perhaps even preventing autoimmune diseases.
