What is the island's cell?
The islets of the islands are a type of cell that secrete insulin located in the pancreas. These cells are collected in the abdominal regions called Langerhans Islands, where they produce several other hormones in addition to insulin. The cells are named after German scientist Paul Langerhans. In a healthy adult human pancreas, there are approximately one million island cells, of which there are five known types.
The most common type of island cell in the pancreas is a beta cell. These are cells that produce insulin, one of the main hormones involved in maintaining a healthy level of blood sugar. Other types of island cells include alpha cells that produce glucagon, delta cells producing somatostatin, epsilon cells producing ghrelin and PP cells that produce pancreatic polypeptide. For example, glucagon increases blood sugar levels, and Thpoto has an accurate opposite effect of insulin that lowers blood sugar levels. Somatostatin produced by Delta cells is involved in a number of paths that act in such a way thatThey limit the release of human growth hormone and regulate digestion. Ghrelin is a hormone stimulating hunger, while the pancreatic polypeptide is mainly involved in the regulation of secretion of several pancreatic hormones.
One of the main diseases that can affect pancreatic island cells is diabetes 1. This type of diabetes develops as a result of the type of immune dysfunction called autoimmunity. A person with diabetes 1. The type cannot produce insulin because the immune system attacked and destroyed all insulin producing island cells in the pancreas. Until recently, the only available medical treatment for diabetes 1 is.
New and potentially effective treatment of diabetes 1. The type is called islets transplantation. In this treatment are beta island cells from the deceased donortransplanted into the liver or pancreas of a person with diabetes 1. If this treatment is successful, the patient may provide cells that can still produce normal insulin supply for one year or more. The person who receives donor cells must take immunosuppressive drugs to prevent rejection of the transplant by the immune system. Currently, this treatment is mainly reserved for people who are unable to control insulin injections and a diet reduction and who are threatened by severe hypoglycaemic episodes.
