tokens: In contrast to the purely enhancer-dependent effect of cytokines such as TNF on the activity of the HIV regulatory region ( LTR ) , we observed that okadaic acid ( OKA ) activates HIV transcription through both the enhancer , responding to the factor NF-kappa B , and the promoter domain of the LTR .
