DEATH DUEL: One TNF receptor 1 pathway activates apoptosis, another triggers gene expression-roles in seeming opposition, says David Goeddel.

Two of the most important activities of the common cytokine tumor necrosis factor (TNF) are to signal apoptosis and to initiate NF-kappa B activation. The signaling starts at the TNF receptor 1 (TNFR1) and moves downstream in a series of biochemical reactions, which until recently were mostly unknown.
"This paper really starts to show how complex the TNF receptor 1 signaling pathway is," says David V. Goeddel, CEO of Tularik Inc., a San Francisco-based biotech company engaged in developing new pharmaceutical products....
