Islet transplantation is a medical procedure in which insulin-producing islet cells are transplanted into the pancreas of a person with type 1 diabetes. The goal of islet transplantation is to restore the patient's ability to produce insulin and regulate blood sugar levels without the need for insulin injections. Islet transplantation is considered a promising treatment for type 1 diabetes, as it can potentially provide long-term relief from the symptoms and complications of the disease. Research in this area focuses on improving the success rate of islet transplantation, reducing the need for immunosuppressive drugs, and developing better methods for preserving and transplanting islet cells.
