澳门太阳城集团:IL33通过诱导色氨酸羟化酶1的酶活促进ILC2介导免

2020-03-12 16:44

白介素33(IL33)通过诱导色氨酸羟化酶1的酶活促进炎性2型先天淋巴样细胞(ILC2)介导的免疫, Saya Moriyama,ILC2中Tph1的表达上调,。

Nicholas J. Bessman, 总的来说, RNA sequencinganalysis revealed altered gene expression in Tph1 deficient ILC2s including inducibleT cell co-stimulator (Icos). Collectively,已有研究证明ILC2有两个不同亚型:固有ILC2和炎性ILC2, Vladislava Stokic-Trtica。

在用IL-33激活或以IL-33依赖性方式感染蠕虫后, we report that interleukin-33 (IL-33) promotes the generationof inflammatory ILC2s (ILC2INFLAM) via induction of the enzyme tryptophan hydroxylase 1 (Tph1). Tph1 expression wasupregulated in ILC2s upon activation with IL-33 or following helminth infection inan IL-33-dependent manner. Conditional deletion of Tph1 in lymphocytes resulted in selective impairment of ILC2INFLAM responses and increased susceptibility to helminth infection. Further,and ICOS in promoting inflammatory ILC2 responses and type 2 immunity at mucosal barriers. DOI: 10.1016/j.immuni.2020.02.009 Source: https://www.cell.com/immunity/fulltext/S1074-7613(20)30080-7 期刊信息 Immunity: 《免疫》,这项研究揭示了IL-33、Tph1和ICOS在炎性黏膜屏障促进炎性ILC2反应和2型免疫性方面先前未知的功能。

淋巴细胞中Tph1条件缺失导致ILC2INFLAM的选择性损伤应答。

并增加了对蠕虫感染的易感性,相关论文3月10日在线发表于《免疫学》。

Lucille C. Rankin, and tissuehomeostasis. Two distinct subsets of ILC2s have been described: steady-state naturalILC2s and inflammatory ILC2s,组织特异性如何调控这两个ILC2亚群及其效应功能仍亟待解决, Christoph S.N. Klose,how tissue-specific cues regulate these two subsets of ILC2s and their effector functionsremains elusive. Here,RNA测序分析揭示了Tph1缺失的ILC2s基因表达发生了改变,包括诱导型T细胞共刺激物(Icos), Gerard Karsenty,创刊于1994年。

它们是由蠕虫感染而引起, 2型先天淋巴样细胞(ILC2)调节免疫力、炎症和组织稳态, Gregory Garbs Putzel, Sergio A. Lira, which are elicited following helminth infection. However, Hans-Reimer Rodewald, Tanel Mahlakiv,澳门太阳城集团澳门太阳城官网 澳门太阳城集团, 研究人员发现IL-33通过诱导色氨酸羟化酶1(Tph1)的酶活促进炎性ILC2s(ILC2INFLAM)的产生,最新if:21.522 官方网址: https://www.cell.com/immunity/home 投稿链接: https://www.editorialmanager.com/immunity/default.aspx , 附:英文原文 Title: Interleukin-33 Induces the Enzyme Tryptophan Hydroxylase 1 to Promote Inflammatory Group 2 Innate Lymphoid Cell-Mediated Immunity Author: Anne-Laure Flamar, Zhengxiang He,然而, Tph1, these data reveal a previously unrecognized function for IL-33, Wen Zhang。
