aP2 (adipocyte Protein 2)^[5] is a carrier protein for fatty acids that is primarily expressed in adipocytes and macrophages. aP2 is also called fatty acid binding protein 4 (FABP4). Blocking this protein either through genetic engineering or drugs^[6] has the possibility of treating heart disease and the metabolic syndrome.^[7]
