tokens: Our studies now demonstrate that HTLV-1 Tax activates the recently identified cellular kinases IkappaB kinase alpha ( IKKalpha ) and IKKbeta , which normally phosphorylate IkappaB alpha on both of its N-terminal regulatory serines in response to tumor necrosis factor alpha ( TNF-alpha ) and interleukin-1 ( IL-1 ) stimulation .
