title: Regulation of NF-kappaB by the HTLV-1 Tax protein.
abstract: The Tax protein encoded by the human T-cell leukemia virus type 1 (HTLV-1) activates viral gene expression via the ATF/CREB pathway. Tax also induces a variety of cellular genes through activation of the transcription factor NF-kappaB. The ability of Tax to activate the NF-kappaB pathway plays an essential role in HTLV-1-induced cellular transformation. This review briefly summarizes the remarkable discoveries of the past several years that have greatly advanced our knowledge on signal-mediated activation of the NF-kappaB pathway. It highlights our current understanding of how viral agents like Tax modulate cellular signaling machinery to activate the NF-kappaB pathway.
