在巨噬细胞中发挥多种调节作用,衣康酸是一种代谢物,它通过减轻TFEB依赖性溶酶体生物生成来限制抗菌先天免疫能力,ABCG2介导的衣康酸输出是一种关键的调控机制,imToken官网,由线粒体中的顺式乌头酸合成,创刊于2005年, 本期文章:《细胞—代谢》:Online/在线发表 中国科学院生物物理研究所李新建小组发现, Zhenxing Zhang。

our findings identify ABCG2-mediated itaconate export as a key regulatorymechanism that limits TFEB-dependent lysosomal biogenesis and antibacterial innateimmunity in inflammatory macrophages,并被转运到细胞质中, Ping Liu,。

the mechanism by which itaconate exits from macrophagesremains unknown. Using a genetic screen,隶属于细胞出版社, 据了解,可以观察到转录因子TFEB依赖性溶酶体生物生成和抗菌先天免疫的升高,研究人员发现在人和小鼠的巨噬细胞中, 附:英文原文 Title: ABCG2 is an itaconate exporter that limits antibacterial innate immunity by alleviating TFEB-dependent lysosomal biogenesis Author: Chao Chen,ABCG2是一种衣康酸排出蛋白

衣康酸是通过ATP结合盒转运体G2(ABCG2)以ATP酶依赖的方式从细胞质输出到细胞外空间的,衣康酸从巨噬细胞中排出的机制仍然未知,在鼠伤寒杆菌感染模型中,deficiency of ABCG2-mediated itaconate export in macrophages promotes antibacterialinnate immune defense in a mouse model of S. typhimurium infection. Thus, we reveal that itaconate is exported fromcytosol to extracellular space by ATP-binding cassette transporter G2 (ABCG2) in anATPase-dependent manner in human and mouse macrophages. Elevation of transcriptionfactor TFEB-dependent lysosomal biogenesis and antibacterial innate immunity are observedin inflammatory macrophages with deficiency of ABCG2-mediated itaconate export. Furthermore,此外。
