FICZ Exposure and Viral Infection in Mice

[Abstract]  The aryl hydrocarbon receptor (AHR) is known as a sensor for dioxins that mediates their toxicity, and also has important biophysiological roles such as circadian rhythms, cell differentiation and immune responses. 6-formylindolo(3,2-b)carbazole (FICZ), which is derived through the metabolism of L-tryptophan by ultraviolet B irradiation, is one of putative physiological ligands for AHR (Smirnova et al., 2016). It has recently been shown that endogenously-activated AHR signaling modulates innate immune response during viral infection (Yamada et al., 2016). This section describes how to treat mice with FICZ and to infect them with virus. [摘要]  芳烃受体(AHR)被称为二恶英介导其毒性的传感器,也具有重要的生物生理学作用,如昼夜节律,细胞分化和免疫应答。通过紫外线B照射通过L-色氨酸的代谢衍生的6-甲酰基吲哚(3,2-b)咔唑(FICZ)是AHR的推定生理配体之一(Smirnova等人)。 ,2016)。最近已经显示内源性激活的AHR信号调节病毒感染期间的先天免疫应答(Yamada等人,2016)。本节介绍如何用FICZ治疗小鼠并用病毒感染。

背景 迄今为止,AHR的作用主要是在二恶英治疗实验的基础上进行了调查。另一方面,已经显示AHR介导的信号传导是由内源色氨酸代谢物(FICZ,Kynurenine,等等),血红素代谢物(胆红素等)激活的。 ,和类二十烷酸(Lipoxin A等)。特别地,已经证明FICZ是AHR的生理高亲和力配体,许多积累的报道显示FICZ参与各种基本生物学过程,包括对紫外线的适应性反应,免疫应答,基因组不稳定性和干细胞的体内平衡。最近,Yamada等人。 (2016)证明其在先天免疫应答中的作用:体内FICZ治疗抑制响应于病毒感染的I型干扰素(IFN)产生并促进小鼠血清中病毒滴度的水平。

[Abstract]  Regulatable protein fusions can be made by attaching the hormone binding domain of the estrogen receptor to the N or C-terminus of a protein of interest. Activation of such ER-fusion proteins in vivo can be achieved by daily administration of a synthetic ligand, 4-hydroxytamoxifen (4OHT), via intraperitoneal (i.p.) injection. [摘要]  可调节的蛋白质融合体可以通过将雌激素受体的激素结合结构域连接到目标蛋白质的N或C末端来制备。 这种ER-融合蛋白在体内的激活可以通过每日通过腹膜内(i.p.)注射施用合成配体4-羟基他莫昔芬(4OHT)来实现。
