Over the past 10 years, many different transcription factors have been identified that direct CD4+ T cell subphenotypes by initiating and sustaining unique transcriptional programs. Below, I show that expression of the transcription factor Tbx21 (T-bet) is necessary for diabetes in the NOD mouse....
TBX21-deficient mice showed impaired Th1 differentiation, including defective IFN-γ production primarily in the CD4 and γδ T cells (Szabo et al., 2002; Yin et al., 2002). Glimcher and colleagues developed an animal model of spontaneous Th2-like, asthma-like syn- drome, and they ...

CD4+细胞分化的T细胞特异性转录因子,调控Thl 目前认为RA是一种多基因遗传病,同时受环境因 化,也是CD8+原始T细胞分化为细胞毒性T淋巴 素和遗传因素的影响[1I。TBX21基因也被称为 T-bet,位于染色体17q21.32,是T-box转录因子家族 水平的降低与机体对病毒感染的反应性降低有 ①本文受I匹IJII省杰出青年基金(No.09...
complete IL-12R. Upon binding of IL-12, Th1 differentiation is initiated and is then sustained by IL-18 signaling. (B) Memory Th1 response. Memory CD4+T cells express IL-12R, IL-18R, and IL-23R (but not IL-27R). IL-18 acts to sustain the Th1 response initiated by IL-12 and IL...
T-bet是Th1特异性转录调节因子,属T-box蛋白家族成员.T-bet上调 IFN-γ转录和IL-12Rβ2表达,提高T细胞对IL-12信号传递的敏感性,从而促进初始Th细胞分化为Th1细胞[1].目前已发现在人体 CD4+T细胞,NK细胞,CD8+效应T细胞中表达T-bet,且与宿主炎症反应,抗病原体免疫应答关系密切[2, 3].对孪生子研究还发现,宿主...
We identified four immune response clusters: 'T cells' (CD3E/CD8A/TBX21/IFNG/FOXP3/IDO1), 'Macrophages' (CD4/CD14/CD163), 'Th2' (IL4/IL5/IL... S Punt,JJ Houwing-Duistermaat,IA Schulkens,... - 《Molecular Cancer》 被引量: 41发表: 2015年 加载更多来源...
T细胞表面免疫球蛋白-黏蛋白样结构蛋白1(T cell immunoglobin domain and mucin domain protein 1,TIM-1)是一种膜表面糖蛋白,表达于CD4+T辅助细胞表面,影响CD4+T辅助细胞发生Th1/Th2极化的关键时期.其在活化的Th2细胞表面高表达,作为共刺激分子,诱导Th2活化增殖.与此同时,TIM-1也是目前已知的甲型肝炎病毒进入...
目前已发现在人体CD4+T细胞、NK细胞、CD8+效应T细胞中表达T-bet,且与宿主炎症反应、抗病原体免疫应答关系密切[2,3]。对孪生子研究还发现,宿主遗传因素对TBX21基因(其编码T-bet)表达及其调控的Th1细胞分化起主要作用;Th2应答不受遗传因素影响,而受T-bet诱导的Th1应答所调控[4]。人类基因组中存在广泛的多态性,...
