深入解析NLRP3、NF-κB P65、TLR4与IL-1β信号通路的相互作用机制
2024年12月30日 · TNF-alpha是一种重要的炎症介质,能够诱导RELA/NF-KB p65的激活和核转运,进而促进炎症反应。 NLRP3通过抑制TNF-alpha的活性,可以间接地影响NF-KB信号通路的激活状态。
NF-κB p65 (RELA)靶点介绍及实验小贴士| Abcam中文官网
NF-κB p65的翻译后修饰可能需要条件诱导,例如Calyculin A和TNF-a刺激细胞后,可检测到536位丝氨酸被磷酸化修 饰的NF-κB p65蛋白。 由于NF-κB p65存在这些翻译后修饰,因此在WB实验时,这些翻译后修饰可能会影响NF-κB p65蛋白大小和条带数目。

NF-κB p65的翻译后修饰可能需要条件诱导,例如Calyculin A和TNF-a刺激细胞后,可检测到536位丝氨酸被磷酸化修饰的NF-κB p65蛋白。 使用新鲜制备的样本,防止冻存样本导致磷酸化修饰减弱。
The Regulation of NF-κB Subunits by Phosphorylation - PMC
Phosphorylation of p65 at T254 by an unknown kinase is induced by TNFα, and results in a phosphorylated threonine-proline motif that is recognised by the peptidyl-prolyl isomerase Pin1. Pin1-mediated prolyl isomerisation of p65 leads to reduced IκBα binding, p65 nuclear accumulation, increased p65 stability and enhanced transcription [77,78 ...

2012年2月1日 · Here we report that TNFα acts through NFκB signaling and requires a conserved promoter region for the down-regulation of Cldn5 expression. Overexpression of the NFκB subunit p65 (RelA) alone repressed Cldn5 promoter activity in mouse brain endothelial cells.

NLRP3抑制TNF-alpha,TNF-alpha诱导RELA/NF-KB p65的激活和核转运。 NLRP3激活caspase-1,响应细菌或病毒感染等多种触发因素,导致IL1B和IL18的加工和释放。 炎症小体通路(图2)。
KPNB1, XPO7 and IPO8 Mediate the Translocation ofNF‐κB/p65 …
2013年8月1日 · Our data showed that knockdown of KPNB1, XPO7 and IPO8 reduced the amount of nuclear p65 following tumor necrosis factor-α (TNF-α) stimulation, resulting in lower NF-κB activity. KPNB1 was the major importin β receptor for p65 import, and this import was dependent on the NLS of p65.
