就是T细胞里头细胞膜表面带有CD4受体分子的细胞,我们常称它为辅助性T细胞(Th,Helper T cell),它主要帮助刺激B细胞产生抗体,没有Th细胞的帮助,B细胞几乎不能分泌抗体。 初始CD4+T细胞受抗原刺激后可分化为Th1、Th2、Th9、Th17、Tfh等效应T细胞,分别分泌不同...
Definition Are CD4 T cells that can help B cells to make antibody in response to antigenic challenge. The most efficient helper T cells are also known as Th2 cells, which make the cytokines IL-4 and IL-5. Some experts refer to all CD4 T cells, regardless of function, as helper T ...
CD4+T细胞可辅助启动 CD8+T 细胞的基因表达程序,通过多种分子机制增强 CTL 功能[27]:第 1 个启动步骤由在淋巴结或脾脏的不同区域的 CD4+T 细胞和 CD8+T 细胞以非同步的方式进行;在第 2 个启动步骤中,CD4+T 细胞和 CD8+T ...
T helper (Th) cells are CD4+T cells that play a central role in the adaptive immune system, by facilitating the activity of other immune cells – especially antigen-presenting cells (APCs) such as B cells, macrophages, anddendriticcells – through the release of cytokines and chemokines. They...
MojoSort™ Human CD4 Naïve T Cell Isolation Kit - Non-CD4+ Naïve T cells are depleted by incubating the sample with the biotin antibody cocktail followed by incubation with magnetic Streptavidin Nanobeads.
CD4+ T细胞和B细胞的相互作用是产生保护性抗体反应的基础,也是有害自身免疫性疾病发展的基础。最近对人体组织和血液样本的研究建立了一个新的CD4+ B辅助T细胞亚群,称为外周辅助T细胞(peripheral helper T, Tph)细胞。不像T滤泡辅助细胞(Tfh),它与淋巴器官内的B细胞相互作用,Tph细胞提供帮助B细胞在发炎的组织。Tph...
Pathogenic T helper type 2 cells (pTh2) are involved in allergic asthma and secrete high levels of IL-5 and IL-13. Here, using HDM challenged mice and developing an in vitro pTh2 culture system, the authors investigate the function of epigenetic modifications in pTh2 cells showing that HDAC...

细胞免疫疗法已经显示出抗肿瘤免疫治疗的独特优势。在免疫细胞抗肿瘤治疗中,CD4+T细胞可以通过发育分化为滤泡辅助T细胞(follicular T helper cells; TFH)并通过调节生发中心(germinal center; GC),可以直接影响B细胞分化和成熟,介导抗肿瘤体液适应性免疫调节。然而,TFH细胞分化和调节的机制目前尚不完全清楚。
CD4+helper Tcells express the CD4 co-receptor and play an important role in the adaptive immune system by assisting other white blood cells. These cells are activated when they are presented an antigen on the MHC class II molecule of an antigen presenting cell (APC). Once activated, CD4+hel...
