γ cells

γ cells or PP cells as they are otherwise known are a small subset of cells located within the islets of Langerhans of the pancreas. The pancreas is a very important organ located just behind and below the stomach, which is responsible for producing many of the hormones we need to keep the level of sugar within our blood at the right level.

The γ cells within the pancreas fulfill a very important role that is still not fully understood. They produce a hormone called pancreatic polypeptide or PP for short, which has a role in telling the pancreas to release its contents. The release of PP is triggered by a number of factors, namely protein rich meals, fasting, exercise and a low blood sugar, known as hypoglycaemia. The main function of PP is to increase the transit of food through the gastro-intestinal system.
