aP2 (adipocyte Protein 2)[2] 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[3][4] has the possibility of treating heart disease,[5] diabetes,[6] asthma,[7] obesity,[8] and fatty liver disease.[9]
