Biochemical Analysis of Caspase-8-dependent Proteolysis of IRF3 in Virus-infected Cells

[Abstract]  Interferon regulatory factor 3 (IRF3) is a transcription factor, which is critical for the antiviral response against a wide range of viruses (Hiscott, 2007; Ikushima et al., 2013). It gets activated in virus-infected cells via Toll like receptors (TLRs), RIG-I (retinoic acid inducible gene 1) like receptors (RLRs), cyclic GMP-AMP synthase (cGAS) – stimulator of interferon genes (STING), which are sensors of viral components in the cells (Chattopadhyay and Sen, 2014a; 2014b; Hiscott, 2007). IRF3 is a cytoplasmic protein, upon activation by virally activated sensors it gets ... [摘要]  干扰素调节因子3(IRF3)是一种转录因子,对于广泛病毒的抗病毒反应至关重要(Hiscott,2007; Ikushima等,2013)。通过Toll样受体(TLR),RIG-I(视黄酸诱导型基因1)受体(RLR),环状GMP-AMP合成酶(cGAS) - 干扰素基因刺激剂(STING),其在病毒感染的细胞中被激活,其中是细胞中病毒组分的传感器(Chattopadhyay和Sen,2014a; 2014b; Hiscott,2007)。 IRF3是一种细胞质蛋白,当被病毒激活的传感器激活时,其被磷酸化,转移到细胞核并与基因启动子的干扰素敏感反应元件(ISRE)结合以诱导其转录(Hiscott,2007)。 IRF3具有其他功能,包括直接刺激病毒感染细胞凋亡。在该途径中,不需要IRF3的转录活性(Chattopadhyay等,2013b; Chattopadhyay等,2016; Chattopadhyay等,2010; Chattopadhyay和Sen,2010; Chattopadhyay等,2011)。这些途径受宿主因素以及病毒的负调控。我们的研究表明IRF3可以通过caspase-8依赖性切割进行蛋白水解加工(Sears等,2011)。 ...

[Abstract]  Among the seven serines and one threonine in the carboxyl-terminus of HBV C protein, all but one (serine 183) appear in the context of RxxS/T consensus phosphoacceptor motifs and also overlap with other consensus motifs, such as S/TP, RS, SPRRR, RRRS/T, or RRxS/T, suggesting that various cellular kinases phosphorylate these residues. To determine whether threonine and/or serine (serines 157, 164, 170, 172, 178, and 180, and threonine 162, adw subtype) of HBV C protein are indeed phosphoacceptor residues in cells, Huh7 were transfected with a series of C-protein-expressing mutants, labeled ... [摘要]  在HBV C蛋白的羧基末端中的七个丝氨酸和一个苏氨酸中,除了一个(丝氨酸183)外,所有其它丝氨酸出现在RxxS/T共有磷酸受体基序的上下文中,并且还与其他共有基序重叠,例如S/TP,RS ,SPRRR,RRRS/T或RRxS/T,表明各种细胞激酶磷酸化这些残基。 为了确定HBV C蛋白的苏氨酸和/或丝氨酸(丝氨酸157,164,170,172,178和180以及苏氨酸162,adw亚型)是否确实是细胞中的磷酸受体残基,Huh7用一系列C- 蛋白表达突变体,用正磷酸32P标记14小时,然后裂解。 用抗HBc抗体免疫沉淀 32 P标记的裂解物,并通过放射自显影检测32 P标记的免疫沉淀的C蛋白。

[Abstract]  We developed this protocol to assay the extent of proliferation of Pseudomonas syringae pv. glycinea in soybean leaves. This method specifically enables accurate pathogenesis assays of soybean plants at V2/V3 (2nd/3rd trifoliate) or higher stages of growth. The leaves of soybean plants at these growth stages are not amenable to bacterial infiltration using routine needleless syringe infiltration due to the high number of trichomes on these mature leaves. This method enables efficient infiltration of bacteria into the epidermal cells of mature leaves ... [摘要]  我们开发了该方案来测定丁香假单胞菌pv的增殖程度。 在大豆叶中。 该方法特异性地能够在V2/V3(2期/3期/3期/3期/3期/3期)或更高生长阶段进行大豆植物的准确发病机理测定。 由于这些成熟叶上的大量毛状体,大豆植物在这些生长阶段的叶子不适于使用常规无针注射器浸润的细菌浸润。 该方法使用压力泵能够有效地将细菌浸润到成熟叶的表皮细胞中。
