Abstract

Rip1 is required for IkappaB kinase activation in response to tumor necrosis factor alpha (TNF-alpha) and has been implicated in the Toll-like receptor 3 (TLR3) response to double-stranded RNA. Cytokine production is impaired when rip1-/- cells are treated with TNF-alpha, poly(I-C), or lipopolysaccharide, implicating Rip1 in the Trif-dependent TLR3 and TLR4 pathways. To examine the role of Rip1 in the Trif-dependent TLR4 pathway, we generated rip1-/- MyD88-/- cells. Lipopolysaccharide failed to stimulate NF-kappaB activation in rip1-/-MyD88-/- cells, revealing that Rip1 is also required for the Trif-dependent TLR4-induced NF-kappaB pathway. In addition to activating NF-kappaB, TLR3/4 pathways also stimulate interferon regulatory factor 3 activation. However, we find that Rip1 expression stimulates NF-kappaB but not interferon regulatory factor 3 activity. In the TNF-alpha pathway, Rip1 interacts with the E3 ubiquitin ligase Traf2 and is modified by polyubiquitin chains. Upon TLR3 activation, Rip1 is also modified by polyubiquitin chains and is recruited to TLR3 along with Traf6 and the ubiquitin-activated kinase Tak1. These studies suggest that Rip1 uses a similar, ubiquitin-dependent mechanism to activate IkappaB kinase-beta in response to TNF-alpha and TLR3 ligands.

About these checks

Registry, retraction, Cites and statistics results are computed, not judged, with one exception: a printed reference that no index lists is read once by a model before it counts as a citation error. Claims are extracted by a model and kept only when their quote appears verbatim in the text; each cited source is then checked, with a model’s help, for whether it says what the claim relies on. Those verdicts can be wrong — read the claim’s quote and the cited source before relying on one.

Statistics and arithmetic are recomputed, not judged.

Confidence bands are shown only for fields calibrated on our annotated test set. None is calibrated yet, so no band is shown.
