NFKB1 — TLR5
Text-mined interactions from Literome
Horng et al., Nat Immunol 2001
:
Although some cellular responses are completely abolished in MyD88-deficient mice,
TLR4 , but not TLR9, can
activate NF-kappa B and mitogen activated protein kinases and induce dendritic cell maturation in the absence of MyD88
An et al., Immunology 2002
:
While inhibition of extracellular signal related kinase and
NF-kappaB activation
suppressed the up-regulation of the expression of TLR2,
TLR4 and TLR9 mRNA, inhibition of p38 kinase prevented the up-regulation of TLR2 and TLR4 mRNA expression but enhanced the up-regulation of TLR9 expression
Takami et al., J Immunol 2002
:
Moreover, various
TLR ligands ( e.g., peptidoglycan, poly ( I:C ) dsRNA, LPS, and CpG motif of unmethylated DNA, which act as ligands for TLR2, 3, 4, and 9, respectively )
induced NF-kappa B activation and up-regulated TNF-alpha production in osteoclast precursor cells
Zhang et al., FEBS Lett 2002
:
NF-kappaB activation by TLR2/1,
TLR2/6 and the TLR4 monomer, but not TLR4/4, was completely inhibited by dominant negative MyD88, suggesting that TLR4 homodimers and monomers could activate NF-kappaB through different mechanisms
Jiang et al., J Biol Chem 2003
(MAP Kinase Signaling System) :
However, we find that, in response to dsRNA,
TLR3 can
mediate the activation of both
NFkappaB and mitogen activated protein ( MAP ) kinases in IL-1-unresponsive mutant cell lines, including IRAK-deficient I1A and I3A cells, which are defective in a component that is downstream of IL-1R but upstream of IRAK
Akira et al., J Infect Dis 2003
:
After stimulation,
TLR recruits IL-1R associated kinase via adaptor myeloid differentiation factor 88 ( MyD88 ) and
induces activation of
NF-kappaB and mitogen activated protein kinases
Janssens et al., FEBS Lett 2003
:
MyD88 is an adapter protein that is involved in
Toll-like receptor ( TLR ) - and interleukin-1 receptor (IL-1R) induced
activation of
nuclear factor-kappaB (NF-kappaB) and c-Jun N-terminal kinase (JNK) ... MyD88 ( S ) is not able to activate NF-kappaB, and in contrast functions as a dominant negative inhibitor of
TLR/IL-1R induced
NF-kappaB activation
Tallant et al., BMC microbiology 2004
(Central Nervous System Neoplasms...) :
Surprisingly, a number of cell lines found to be unresponsive to flagellin express
TLR5 and expression of exogenous TLR5 in these cells
induces NF-kappa B activity in response to flagellin challenge although not robustly
Akira et al., C R Biol 2004
:
Upon stimulation,
TLR recruits a cytoplasmic adaptor molecule MyD88, then IL-IR associated kinase ( IRAK ), and finally
induces activation of
NF-kappaB and MAP kinases
Pivarcsi et al., Acta Microbiol Immunol Hung 2004
:
In response to challenge with microbes or microbial derived substances the activation and nuclear translocation of
NF-kappaB , the production of nitric oxide ( NO ) and inflammatory cytokines occur in keratinocytes, in a
TLR dependent manner
Seki et al., Hepatology 2005
:
However,
TLR2 , 4 and 9, which recognize gram negative and -positive bacterial products, are not
essential for
NF-kappaB activation and IL-6 production after PH, which excludes a possible contribution of TLR2/TLR4 or TLR9 to MyD88 mediated pathways
Bucki et al., Biochemistry 2005

Additionally,
TLR dependent
NF-kappaB translocation in astrocytes appears to be blocked by gelsolin
Abujamra et al., Virology 2006

Using Toll-like receptor ( TLR ) deficient HEK293 cells and PKR ( -/- ) mouse embryo fibroblasts, we further demonstrate that although dsRNA activated protein kinase R (PKR) is not necessary,
TLR3 is
required for the activation of
NFkappaB by the LTR

:
Therefore, in the present study, we investigated whether globular adiponectin ( gAd ) would be able to inhibit
TLR mediated
nuclear factor-kappaB (NF-kappaB) signaling in mouse macrophages ( RAW264 ) ... gAd predominantly bound to the AdipoR1 receptor and suppressed
TLR mediated
NF-kappaB signaling ... gAd mediated inhibition of
TLR mediated IkappaB phosphorylation and
NF-kappaB activation was eliminated by the pretreatment of cycloheximide
Wang et al., Nat Immunol 2006

Takahashi et al., J Vet Med Sci 2006
:
These observations suggest that immediate response of NODs to endotoxins could result from
NF-kappaB activation via
TLR signaling, whereas the second rise in NOD mRNAs might have resulted from TNF-alpha production possibly through NF-kappaB, TLR, and/or NOD signalings
Kataoka et al., Cell Microbiol 2006
:
TLR2 ( N114A, N199A ), TLR2 ( N114A, N414A ) and, to a lesser extent,
TLR2 ( N114A, N442A ), in which two N-linked glycans are speculated to be exposed to the concave surface of TLR2 solenoid, not only
induce NF-kappaB activation but also are associated with wild-type TLR2 and TLR6

Shamshiev et al., J Exp Med 2007

TLR mediated signaling on CD8alpha ( - ) myeloid DCs and
inhibit NF-kappaB nuclear translocation
Carmody et al., Cell Mol Immunol 2007

Many of the key molecular events required for
TLR induced
NF-kappaB activation have been elucidated
Gringhuis et al., Immunity 2007

TLR induced activation of
NF-kappaB
Karrasch et al., J Immunol 2007

NF-kappaB was normal
Kubo-Murai et al., J Biochem 2008
:
IRAK-4 dependent degradation of IRAK-1 is a negative feedback signal for
TLR mediated
NF-kappaB activation ... These results suggested that the expression of IRAK-4 alone is sufficient to cause the degradation of IRAK-1 ; the autophosphorylation of IRAK-1 is not necessary to terminate the
TLR induced activation of
NF-kappaB

Activation of the transcription factor
NFkappaB through

In this study, chicken TLRs 7, 15 and 21 were expressed in mammalian HEK-293T cells ; expression of
TLR21 but not TLR7 or 15
resulted in marked
NF-kappaB activation upon stimulation with exogenous ODN ...
TLR21 mediated
NF-kappaB activation in HEK-293T cells was inhibited by bafilomycin A suggesting that endosomal maturation is required for TLR21 activation and observations by confocal microscopy and digestion with endoglycosidase H suggest TLR21 localizes to the endoplasmic reticulum ( ER ) of resting cells
