Phos-tag Immunoblot Analysis for Detecting IRF5 Phosphorylation

[Abstract]  While the activation of the transcription factor interferon regulatory factor 5 (IRF5) is critical for the induction of innate immune responses, it also contributes to the pathogenesis of the autoimmune disease systemic lupus erythematosus (SLE). IRF5 phosphorylation is a hallmark of its activation in the Toll-like receptor (TLR) pathway, where active IRF5 induces type I interferon and proinflammatory cytokine genes. By using the phosphate-binding molecule Phos-tag, without either radioisotopes or phospho-specific antibodies, the protocol described here enables detection of the ... [摘要]  虽然转录因子干扰素调节因子5(IRF5)的激活对于诱导先天免疫应答至关重要,但也有助于自身免疫疾病系统性红斑狼疮(SLE)的发病机制。 IRF5磷酸化是其在Toll样受体(TLR)途径中的活化的标志,其中活性IRF5诱导I型干扰素和促炎细胞因子基因。通过使用不含放射性同位素或磷酸特异性抗体的磷酸结合分子磷酸标签,本文所述的方案可以检测人和鼠IRF5以及其他蛋白质的磷酸化。

背景 在TLR-MyD88途径中,IRF5通过翻译后修饰如泛素化和磷酸化被激活,然后活性IRF5转位到细胞核中并诱导其靶基因(Takaoka等人,2005; Balkhi ,2008; Tamura等人,2008; Hayden and Ghosh,2014)。关于IRF5在SLE中的激活状态,已经报道了IRF5积累在SLE患者的单核细胞核中(Stone等人,2012)。此外,我们最近在SLE鼠模型中显示,IRF5超激活(例如,升高的磷酸化)导致SLE样疾病的发展(Ban 等人,,2016年)。因此,分析IRF5的激活状态对于研究SLE以及先天免疫应答是重要的。磷酸化是IRF5激活的核心,因为许多研究已经通过定点诱变和/或质谱法揭示了IRF5的功能性磷酸化位点(Barnes等人,2002; Lin et al。等人,2005; ...

[Abstract]  Human hepatic cancer cell lines such as HepG2, Huh7, and HLE cannot get infected with Hepatitis B virus (HBV) due to lack of an HBV receptor(s). Transfection with HBV genome has so far been referred as a tool to mimic HBV infection. However, since sodium taurocholate cotransporting polypeptide (NTCP) was identified as a functional receptor for HBV (Yan et al., 2012), hepatocyte cell lines that were stably transfected with a plasmid for NTCP expression have been used for HBV infection. This protocol is designed for infection with HBV in human hepatocyte cell line HepG2 expressing NTCP ... [摘要]  人肝癌细胞系如HepG2,Huh7和HLE由于缺乏HBV受体而不能感染乙型肝炎病毒(HBV)。 HBV基因组的转染迄今为止被称为模拟HBV感染的工具。 然而,由于牛磺胆酸钠共转运多肽(NTCP)被鉴定为HBV的功能性受体(Yan等人,2012),已经使用用用于NTCP表达的质粒稳定转染的肝细胞细胞系 为HBV感染。 该方案设计用于在表达人类肝细胞细胞系HepG2的表达NTCP(HepG2-hNTCP-C4细胞; Iwamoto等人,2014)或原代人肝细胞(PHH)的HBV感染。 在本节中,我们还描述了用于评估HBV感染的方法之一:细胞内衣壳化的HBV DNA的定量。
