Costimulation of U1 cells with LPS plus GM-CSF resulted in the accumulation of steady-state levels of HIV RNA ; however, only a weak induction of HIV long terminal repeat -driven transcription , which was not associated with the activation of the cellular transcription factor nuclear factor-kappa B , was noted.
 ( DNA: HIV long terminal repeat, None) , ( protein: cellular transcription factor, None) , ( protein: nuclear factor-kappa B, None) , ( RNA: HIV RNA, None) , ( protein: GM-CSF, None) , ( cell line: U1 cells, None)
