Sentences with phrase «islet autoimmunity»

"Islet autoimmunity" refers to a condition where the body's immune system mistakenly attacks and destroys the cells in the islets of Langerhans, which are tiny clusters of cells in the pancreas. These cells are responsible for producing insulin, a hormone that helps regulate blood sugar levels. When islet autoimmunity occurs, it can lead to the development of type 1 diabetes, where the body is unable to produce enough insulin. Full definition
