Transcriptional Control of Synaptic Plasticity by Transcription Factor NF-κB
Activation of nuclear factor kappa B (NF-κB) transcription factors is required for the induction of synaptic plasticity and memory formation. All components of this signaling pathway are localized at synapses, and transcriptionally active NF-κB dimers move to the nucleus to translate synaptic signals into altered gene expression. Neuron-specific inhibition results in altered connectivity of exc...
متن کاملTranscription of Tnfaip3 Is Regulated by NF-κB and p38 via C/EBPβ in Activated Macrophages
Macrophages play a pivotal role in the immune system through recognition and elimination of microbial pathogens. Toll-like receptors (TLRs) on macrophages interact with microbial substances and initiate signal transduction through intracellular adapters. TLR4, which recognizes the lipopolysaccharides (LPS) on Gram-positive and Gram-negative bacteria, triggers downstream signaling mediators and ...
متن کاملInduction of Heme Oxygenase -1 By Lipocalin 2 Mediated By Nf-Kb Transcription Factor
Purpose: Effect of lipocalin 2 on the expression of heme oxygenase I , II and NF-kB transcription factor was the purpose of this survey. Materials and Methods: Lcn2 was cloned to pcDNA3.1 plasmid by using genetic engineering method. The recombinant vector was transfected to CHO and HEK293T to establish stable cell expressing lipocalin 2. The presence of lipocalin 2 gene in these cells was confi...
متن کاملThe dual function cytokine IL-33 interacts with the transcription factor NF-κB to dampen NF-κB-stimulated gene transcription.
Full-length IL-33 is a member of the IL-1 family of cytokines, which can act in an autocrine or paracrine manner by binding to the IL-33R on several different target cell types. In addition, IL-33 can act in an intracrine fashion by translocating to the nucleus, where it binds to the chromatin and modulates gene expression. In this article, we report that full-length IL-33, but not mature IL-33...
متن کاملExtracellular ATP Activates Transcription Factor NF-κB through the P2Z Purinoreceptor by Selectively Targeting NF-κB p65 (RelA)
Cells of the macrophage lineage express a peculiar surface receptor for extracellular ATP, designated P2Z/P2X7 purinergic receptor, that induces pore formation and collapse of the plasma membrane potential. Although the function of the P2Z receptor is largely unknown, accumulating evidence implicates its role in cell signaling and immune reactions. Here, we investigated the effect of P2Z recept...
