What are the causes of type 1 diabetes?

The etiology of type 1 diabetes and type 2 diabetes are different, triggering type 1 diabetes because of the following three aspects:
Genetic factors: The current study suggests that genetic defects in the incidence of type 1 diabetes basis of this genetic defect is manifested in the sixth HLA antigens on chromosome abnormalities. Scientists Tip: type I diabetes incidence of familial characteristics - if your parents have diabetes, and then compared with no such family history, you are more susceptible to the disease.
2, virus infection may be contributory factors: Perhaps your mind, many scientists suspect the virus can also cause type I diabetes. This is because the type I diabetic patients before the onset of a period of time is often too viral infection, and type I diabetes epidemic, often appear after the virus is endemic. Viruses, such as the viruses that cause mumps and rubella, and polio can cause the Coxsackie virus family, can play a role in type I diabetes.
Own immune system defects: to detect a variety of autoimmune antibodies in the blood of patients with type 1 diabetes, such as glutamic acid decarboxylase (GAD), islet cell antibodies (ICA antibodies). These abnormal autoantibodies can damage human islet insulin secretion from B cells, not normal insulin secretion.
