Abstract

Type 1 diabetes is an organ specific autoimmune disease whose incidence is increasing worldwide. A functional imbalance in cytokine production resulting in dominance of T helper (Th1) over Th2-type response has been suggested to play a critical role in the pathogenesis of type 1 diabetes. To measure serum concentrations of interleukin (IL)-1beta, IL-2 and IL-4 in children with recently diagnosed type 1 diabetes and to evaluate the autoimmune response measuring glutamic acid decarboxylase (GAD65) and tyrosine phosphatase like (IA-2) autoantibodies. 120 diabetic children and 118 age and gender matched control children, were recruited for this study. Circulating levels of IL-1beta IL-2 and IL-4 were measured by ELISA. GAD65 and IA-2 were measured by RIA. Circulating levels of IL-1beta were elevated in type 1 diabetic children as compared to the control group (9.3 +/- 7.3 and 4.9 +/- 3.8 pg/ml respectively, p=0.01). Serum concentration of IL-2 was also higher in diabetic patients (19.8 +/- 13.1 and 113 +/- 9.1 pg/ml respectively, p=0.01). No differences in serum IL-4 were observed between diabetics and control. Diabetic children with one or two positive autoantibodies (IA-2 and/or GAD65) had significantly higher levels of IL-1beta ...Continue Reading

Patients with type I diabetes lack insulin-producing beta cells due to the loss of immunological tolerance and autoimmune disease. Discover the latest research on targeting tolerance to prevent diabetes.

Autoimmune Diseases

Autoimmune diseases occur as a result of an attack by the immune system on the body’s own tissues resulting in damage and dysfunction. There are different types of autoimmune diseases, in which there is a complex and unknown interaction between genetics and the environment. Discover the latest research on autoimmune diseases here.
