Together, our results indicate that occupancy of the viral enhancer by NF-kappaB ( p50/p65 ) heterodimers is required for ongoing transcription of integrated HIV provirus in monocytes , even in cells chronically infected and permanently producing functional HIV Tat protein .
 ( DNA: viral enhancer, None) , ( protein: HIV Tat protein, None) , ( cell type: monocytes, None) , ( protein: p50/p65, None) , ( protein: NF-kappaB ( p50/p65 ) heterodimers, None) , ( protein: NF-kappaB, None)
