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][7] has the possibility of treating heart disease,[8] diabetes,[9] asthma,[10] obesity,[11][12] fatty liver disease[13] and cancer[12][14].
