PP cells are one of the rarer pancreatic cell types and are more prevalent in the head and neck of the pancreas. They are critical in normal pancreatic physiological functions and are involved in the development of pancreatic endocrine disorders. The primary function of PP cells is the production and secretion of the pancreatic polypeptide hormone (PP). This hormone plays a crucial role in several gastrointestinal functions and metabolic responses. The release of the PP hormone is stimulated after eating, especially in protein-rich meals, leading to it being present in large amounts during digestion. The fundamental role of PP is to self-regulate pancreatic secretion activities ensuring its exocrine and endocrine functions are under control. The pancreatic polypeptide hormone from PP cells also aids in adapting to low physical activity and fasting by reducing the production of insulin and glucagon and inhibiting the hepatic glucose production. Additionally, this hormone influences gut motility by slowing down the gastric emptying and reducing small intestinal transit, thereby controlling the pace at which nutritional substances are absorbed. Because of these functions, any malfunction or irregularity in PP cells can result in various disorders such as diabetes and pancreatic diseases.
