CD4 T细胞通常也称为辅助性T淋巴细胞(CD4 Helper T Cells),它的成长经历和CD8 T细胞一样,也是在胸腺由淋巴祖细胞经过克隆选择/双阴/双阳等层层筛选分化而成。 与CD8 T细胞活化需要MHCI-抗原复合体不同,CD4 T细胞活化第一信号来自MHCII-抗原复合体。 之所以说CD4 T细胞具有多重人格,主要是不同于钢铁直男CD8 T细胞...

Th22细胞也与表皮免疫力和重塑有关。Th22参与了在银屑病,强直性脊柱炎、桥本甲状腺炎,和多发性硬化症。 另一个亚群Tfh(卵泡辅助性T细胞)促进B细胞的抗原特异性发育并分泌IL-21。滤泡辅助性T细胞(T follicular helper cells, Tfh),是体液免疫中辅助B细胞...
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 cells; we do not accept this usage because function can be determined only in cellular assays, and some ...

这篇题为“The interaction of CD4+ helper T cells with dendritic cells shapes the tumor microenvironment and immune checkpoint blockade response”的文章描述了肿瘤微环境中T细胞与抗原呈递树突状细胞之间的相互作用。 Merad说:“利用Merav(该研究的第一作者)开发的tour de force assay,我们能够分析在人类肿瘤中...

cells (PIC-seq) and find that CD4+PD-1+CXCL13+T cells are a major interacting hub with antigen-presenting cells in the tumor microenvironment of human non-small cell lung carcinoma. We define this clonally expanded, tumor-specific and conserved T-cell subset as T-helper tumor (Tht) cells...
We show that ICB response correlated with the clonal expansion of intratumoral CXCL13+CH25H+IL-21+PD-1+CD4+ T helper cells (“CXCL13+ TH”) and Granzyme K+ PD-1+ effector-like CD8+ T cells, whereas terminally exhausted CD39hiTOXhiPD-1hiCD8+ T cells dominated in nonresponders. CD4+...
