The present study demonstrates that AP-2 binding sequences are essential for increased transcription from the B2 promoter during monocyte-macrophage differentiation and that AP-2 , expressed exogenously in THP-1 and other cells, activates transcription from the B2 promoter .
 ( DNA: B2 promoter, None) , ( DNA: AP-2 binding sequences, None) , ( DNA: B2 promoter, None) , ( protein: AP-2, None) , ( protein: AP-2, None) , ( cell line: THP-1, None)
