Among those signaling pathways, activation of NF-kappaB leads to up-regulation of IL-1beta, IL-8 and TNF-alpha, mucin MUC2 and Toll-like receptor 2 (TLR2), whereas activation of p38 MAP kinase mediates not only up-regulation of inflammatory mediators and mucin MUC5AC but also down-regulation of TLR2.

Moreover, the TGF-beta-Smad signaling pathway cooperates with NF-kappaB to mediate up-regulation of mucin MUC2.

In this study, we used adenoviral vectors to express a model tumor Ag (the E7 oncoprotein of human papillomavirus 16) with or without coexpression of receptor activator of NF-kappaB (RANK)/RANK ligand (RANKL) or CD40/CD40L costimulatory molecules, and used these transgenic DCs to immunize mice for the generation of E7-directed CD8(+) T cell responses.

During Escherichia coli pneumonia, deficiency of NF-kappaB p50 increases gene expression and neutrophil recruitment, suggesting that p50 normally limits these innate immune responses. p50-deficient mice were used to determine how p50 regulates responses to a simpler, non-viable bacterial stimulus in the lungs, E. coli lipopolysaccharide (LPS).

In addition, after CD26-caveolin-1 interaction on TT-loaded monocytes, caveolin-1 is phosphorylated, which links to activate NF-kappaB, followed by up-regulation of CD86.

Furthermore, an electrophoretic mobility shift assay showed that PhIP inhibited DNA binding activity of nuclear factor for immunoglobulin kappa chain in B cells (NF-kappaB), activator protein-1 (AP-1) and nuclear factor of activated T cells (NF-AT), which are known to be responsible for IL-2 transcriptional activation.
|

16168555
|
These results suggest that PhIP has potential immunosuppressive effects by inhibiting T-cell proliferation and IL-2 expression through down regulation of ROS generation and thereby inhibiting NF-kappaB, AP-1 and NF-AT activation.

Activation of GA-12 (a repressor element of IL-12 p40), rather than suppression of promoter elements, such as binding sites for NF-kappaB, AP-1, and IRF-1, was detected in LPS-stimulated RAW264.7 cells, accompanying hyperactivation of extracellular signal-related kinase (ERK).

Here, we describe an approach to enhance immunogenicity that involves the activation of NF-kappaB by the transgenic expression of an intracellular signaling molecule, NF-kappaB-inducing kinase (NIK).
|

|
In vitro, NIK increases dendritic cell antigen presentation in allogeneic and antigen-specific T cell proliferation assays by potently activating NF-kappaB and consequently up-regulating the expression of cytokines (TNF-alpha, IL-6, IL-12, IL-15, and IL-18), chemokines [IL-8, RANTES (regulated on activation, normal T cell expressed and secreted), macrophage inflammatory protein-1alpha, monocyte chemoattractant protein-1, and monocyte chemoattractant protein-3], MHC antigen-presenting molecules (class I and II), and costimulatory molecules (CD80 and CD86).

Besides TLRs, mRNA for MyD88 and TRAF6, and nuclear translocation of NF-kappaB were enhanced that indicate their involvement in tandem in the activity of porin.

16750567
|
Intracellular expression and release of TNF-alpha and IL-12 in presence of porin was found to be TLR2 and NF-kappaB dependent.

Expression of PAdV-3 E1Blarge inhibited the NF-kappaB dependent transcription of luciferase from IL-8 promoter.
|
17 |
17565687
|
These results suggest that E1Blarge interacts with NF-kappaB to prevent transcription and down regulate proinflammatory cytokine IL-8 production.

Neither hexaacylated nor pentaacylated synthetic lipid A induced NF-kappaB activity in wild-type transfectants under the identical transfection conditions used for LPS; however, increasing human MD-2 expression rescued responsiveness to hexaacylated lipid A only, while murine MD-2 was required to elicit a response to pentaacylated lipid A.

Although human B cells bound both human and murine BLyS, nuclear accumulation of NF-kappaB p52, an indication of the induction of a protective anti-apoptotic response, following stimulation with human BLyS was more robust than that induced with murine BLyS suggesting a fundamental disparity in BLyS receptor signaling.

Each purified recombinant V. cholerae flagellin induced IL-8 production in T84 intestinal epithelial cells and also induced nuclear factor kappa B (NF-kappaB) activation in HEK293T/TLR5 transfectants, which was blocked by cotransfection with a TLR5 dominant-negative construct, demonstrating TLR5 specificity.

CD28-mediated signaling through PI3K results in the recruitment of protein kinase C-theta (PKCtheta) to the cSMAC, activation of NF-kappaB, and up-regulation of IL-2 transcription.
|
27 |

|
Mutation of tyrosine 188 also results in diminished activation of NF-kappaB, suggesting that CD28-mediated localization of PKCtheta to the cSMAC is important for efficient signal transduction.

Because the confounding impact of the loss of p50 on the host response to MHV68 infection prevented a direct analysis of the role of this NF-kappaB family member on MHV68 latency in B cells, we generated and infected mixed p50(+/+)/p50(-/-) bone marrow chimeric mice.

|
These results demonstrate that events during the early phase of MVA replication can induce PKR-mediated processes contributing both to the activation of NF-kappaB signaling, and to processes that may restrict viral replication.

|
This domain has the ability to inhibit NF-kappaB activation by interfering with the polyubiquitination process of IkappaBalpha, which subsequently prevents IkappaBalpha degradation.

|
The result showed that certain mutations lethal to virus replication impaired the ability of nsp2 to inhibit NF-kappaB activation but that the viable recombinant viruses, vSD-S462A and vSD-D465A, were unable to inhibit NF-kappaB activation as effectively as the wild-type virus.

DNA-dependent activator of IFN regulatory factors (IRF; DAI, also known as ZBP1 or DLM-1) is a cytosolic DNA sensor that initiates IRF3 and NF-kappaB pathways leading to activation of type I IFNs (IFNalpha, IFNbeta) and other cytokines.
|
50 |
18941233
|
In this study, induction of NF-kappaB is shown to depend on the adaptor receptor-interacting protein kinase (RIP)1, acting via a RIP homotypic interaction motif (RHIM)-dependent interaction with DAI.

|
Suppression of RIP1 expression by RNAi abrogates NF-kappaB activation as well as IFNbeta induction by immunostimulatory DNA.
|
52 |
18941233
|
The role of DAI in activation of NF-kappaB in response to immunostimulatory DNA appears to be analogous to sensing of dsRNA by TLR3 in that both pathways involve RHIM-dependent signaling that is mediated via RIP1, reinforcing a central role for this adaptor in innate sensing of intracellular microbes.

Using an endotoxin free rHagB preparation, our results show that stimulation of murine bone marrow-derived DC with rHagB leads to upregulation of the costimulatory molecules CD86 and CD40, activation of p38 and ERK MAP kinases, transcription factors NF-kappaB, CREB and IRF-3 and the production of IL-6, TNF-alpha, IL-12p40 and to a lesser extent IL-10 and IFN-beta.

NSs induces a shut-off of host transcription including interferon (IFN)-beta mRNA(7,8) and promotes degradation of double-stranded RNA-dependent protein kinase (PKR) at the post-translational level.(9,10) IFN-beta is transcriptionally upregulated by interferon regulatory factor 3 (IRF-3), NF-kB and activator protein-1 (AP-1), and the binding of IFN-beta to IFN-alpha/beta receptor (IFNAR) stimulates the transcription of IFN-alpha genes or other interferon stimulated genes (ISGs)(11), which induces host antiviral activities, whereas host transcription suppression including IFN-beta gene by NSs prevents the gene upregulations of those ISGs in response to viral replication although IRF-3, NF-kB and activator protein-1 (AP-1) can be activated by RVFV7. .
