[Abstract] Activation of the aryl hydrocarbon receptor (AHR) by endogenous ligands has been implicated in a variety of physiological processes such as cell cycle regulation, cell differentiation and immune responses. It is reported that tryptophan metabolites, such as kynurenine (Kyn) and 6-formylindolo(3,2-b)carbazole (FICZ), are endogenous ligands for AHR (Stockinger et al., 2014). This protocol is designed for treatment with Kyn or FICZ in mouse embryonic fibroblasts (MEFs) or primary peripheral monocytes.
[摘要] 通过内源性配体活化芳基烃受体（AHR）已涉及多种生理过程，如细胞周期调控，细胞分化和免疫应答。据报道，色氨酸代谢物，如犬尿胆碱（Kyn）和6-甲基吲哚（3,2-b）咔唑（FICZ）是AHR的内源性配体（Stockinger等人，2014）。该方案设计用于在小鼠胚胎成纤维细胞（MEF）或初级周边单核细胞中用Kyn或FICZ进行治疗。
背景 色氨酸代谢物如Kyn和FICZ是生理条件下AHR的内源性配体。 Kyn由色氨酸-2,3-双加氧酶（TDO）和/或吲哚胺-2,3-双加氧酶1和2（IDO1 / 2）产生，并有助于抑制抗肿瘤反应和恶性进展（Stockinger等人，2014）。 ...

[Abstract] To assess the effect of multipotent stromal cells (MSC) on monocytes, 3-day cultures were performed of freshly isolated monocytes in MSC-conditioned medium (CM). As a control condition, monocytes were stimulated with low dose macrophage colony-stimulating factor (M-CSF). Monocytes were isolated from peripheral blood mononuclear cell (PBMC) populations by magnetic activated cell sorting (MACS) using CD14 microbeads.
[摘要] 为了评估多潜能基质细胞（MSC）对单核细胞的作用，在MSC条件培养基（CM）中对新鲜分离的单核细胞进行3天培养。 作为对照条件，用低剂量巨噬细胞集落刺激因子（M-CSF）刺激单核细胞。 通过磁激活细胞分选（MACS）使用CD14微珠从外周血单核细胞（PBMC）群体中分离单核细胞。

[Abstract] Dendritic cells (DC) are antigen-presenting cells, which play a critical role in the regulation of the adaptive immune response. They act as a bridge between the innate and the adaptive immune systems. An approach to study their function and potentiality is to generate DC-like cells by culturing CD14+ monocyte-enriched peripheral blood mononuclear cells (PBMC). In the presence of GM-CSF and IL-4, these cultures give rise to large numbers of DC-like cells. Generating human-DC from PBMC is a useful tool to study biological functions of human DC.
[摘要] 树突状细胞（DC）是抗原呈递细胞，其在适应性免疫应答的调节中起关键作用。 它们作为先天免疫系统和适应性免疫系统之间的桥梁。 研究它们的功能和潜力的方法是通过培养富集CD14 +单核细胞的外周血单核细胞（PBMC）产生DC样细胞。 在GM-CSF和IL-4存在下，这些培养物产生大量的DC样细胞。 从PBMC产生人类DC是研究人类DC的生物学功能的有用工具。
