Impaired anti-inflammatory response plays role in pathology of type 2 diabetes

Type 2 diabetes is classified as a metabolic disorder, but a growing number of researchers are beginning to think of it also as a disease of the innate immune system. Inflammation, a key component of the early immune response, is chronically elevated in people with type 2 diabetes.
