The American Diabetes Association additionally recommends a diagnosis of diabetes for anyone with symptoms of hyperglycemia and blood sugar at any time at or above 11.1 mmol/L, or glycated hemoglobin (hemoglobin A1C) levels at or above 48 mmol/mol.Once a diagnosis of diabetes is established, type 1 diabetes is distinguished from other types by a blood test for the presence of autoantibodies that target various components of the beta cell. The most commonly available tests detect antibodies against glutamic acid decarboxylase, the beta cell cytoplasm, or insulin, each of which are targeted by antibodies in around 80% of type 1 diabetics. Some healthcare providers also have access to tests for antibodies targeting the beta cell proteins IA-2 and ZnT8; these antibodies are present in around 58% and 80% of type 1 diabetics respectively. Some also test for C-peptide, a byproduct of insulin synthesis. Very low C-peptide levels are suggestive of type 1 diabetes. Management
The mainstay of type 1 diabetes treatment is the regular injection of insulin to manage hyperglycemia. Injections of insulin – via subcutaneous injection using either a syringe or an insulin pump – are necessary multiple times per day, adjusting dosages to account for food intake, blood glucose levels and physical activity. The goal of treatment is to maintain blood sugar in a normal range – 80–130 mg/dL before a meal; <180 mg/dL after – as often as possible. To achieve this, people with diabetes often monitor their blood glucose levels at home.
AKITA mice are used to test drugs targeting endoplasmic reticulum stress reduction, to test islet transplants, and to study diabetes-related complications such as nephropathy, sympathetic autonomic neuropathy, and vascular disease. for testing transplantation therapies. Their advantage is mainly the low cost, the disadvantage is the cytotoxicity of the chemical compounds. Genetically induced
Virally induced
Viral infections play a role in the development of a number of autoimmune diseases, including human type 1 diabetes. However, the mechanisms by which viruses are involved in the induction of type 1 DM are not fully understood. Virus-induced models are used to study the etiology and pathogenesis of the disease, in particular the mechanisms by which environmental factors contribute to or protect against the occurrence of type 1 DM. Among the most commonly used are Coxsackie virus, lymphocytic choriomeningitis virus, encephalomyocarditis virus, and Kilham rat virus. Examples of virus-induced animals include NOD mice infected with coxsackie B4 that developed type 1 DM within two weeks. References
