[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。
