An antibody raised against peptide YY. PYY is a hunger-suppressing hormone secreted in the mucosa of the rectum, colon and distal ileum.

PYY (peptide YY) regulates body mass index and body weight, where decreased levels of PYY are associated with obesity and increased BMI. It reduces hunger and food intake, gastrointestinal motility and hormone secretion by the pancreas. It also plays a role in regulating energy homeostasis. Studies suggest that its expression is decreased under pro-inflammatory stimuli and during the differentiation of monocytes to macrophages. PYY concentrations are also reduced in women with high dietary cognitive restraint (CR) compared to women with normal CR. This peptide is altered in various gastrointestinal disorders and might be one of the causes of chronic idiopathic slow-transit constipation (CST). It might also be responsible for the symptoms of inflammatory bowel disease and gastroenteropathy due to long-standing diabetes. However, in some gastrointestinal disorders, it might have a positive role, as in the case of systemic sclerosis, celiac disease, and post-intestinal resection state.
