[Abstract]  Because transforming growth factor-β (TGF-β1) induces differentiation of fibroblasts to myofibroblasts, we developed a protocol to evaluate alveolar macrophage-derived TGF-β1 regulation of lung fibroblast differentiation (Larson-Casey et al., 2016). The protocol evaluates the ability of mouse bronchoalveolar lavage (BAL) fluid to alter fibroblast differentiation. Fibroblast differentiation was measured by the expression of α-smooth muscle actin (α-SMA). [摘要]  因为转化生长因子-β(TGF-β1)诱导成纤维细胞分化成肌成纤维细胞,我们开发了评价肺泡巨噬细胞衍生的TGF-β1调节肺成纤维细胞分化的方案(Larson-Casey等人)。 ,2016)。该方案评价小鼠支气管肺泡灌洗液(BAL)流体改变成纤维细胞分化的能力。通过α平滑肌肌动蛋白(α-SMA)的表达测量成纤维细胞分化。

[背景] 肺泡巨噬细胞通过增加肺纤维化发展起到不可或缺的作用TGF-β1的表达(He等人,2011)。我们的先前数据表明,肺泡巨噬细胞是TGF-β1的关键来源,因为在巨噬细胞中具有条件缺失的TGF-β1的小鼠被保护免于肺纤维化(Larson-Casey等人,2016)。 α-SMA的表达是肌成纤维细胞的定义特征,并且TGF-β1是良好表征的促纤维化介质,其在体外诱导成纤维细胞向肌成纤维细胞的转化(Desmoulière等人。,1993)和 in vivo (Sime等人,1997)。先前的研究将成纤维细胞暴露于重组TGF-β1以显示其对分化和功能的作用(Horowitz等人,2007)。在这里,我们开发了一个协议,确定小鼠BAL液的能力改变人类肺成纤维细胞分化成肌纤维母细胞,细胞外基质蛋白的细胞。

[Abstract]  T follicular helper (Tfh) cells constitute a distinct subset of CD4+ T cells specialized in providing help to B cells in germinal centers. Phenotypically, Tfh cells are characterized by their high expression of the chemokine receptor CXCR5 that allows their migration into B cell follicles as well as high expression of PD-1, BTLA, the co-stimulatory molecules ICOS and SLAM and the transcription factors BCL6 and cMaf. Tfh cells are the main producers of IL-21 as well as other cytokines like IL-4 and IL-10 critical for B cell survival and differentiation. Tfh cells drive somatic hypermutation and the generation of long-lived memory B cells and plasma cells having an essential role in the development of protective immunity. Developing a coculture system to measure the effects of ... [摘要]  T滤泡辅助(Tfh)细胞构成专门提供对生发中心中的B细胞的帮助的CD4 + T细胞的不同亚群。表型上,Tfh细胞的特征在于其高趋化因子受体CXCR5的表达,其允许它们迁移到B细胞滤泡以及PD-1,BTLA,共刺激分子ICOS和SLAM以及转录因子BCL6和cMaf的高表达。 Tfh细胞是IL-21以及其他细胞因子如IL-4和IL-10对B细胞存活和分化关键的主要生产者。 Tfh细胞驱动体细胞超突变和长寿记忆B细胞和浆细胞的产生在保护性免疫的发展中具有重要作用。开发共培养系统以测量Tfh细胞介导的B细胞帮助的效果是非常感兴趣的进一步我们的Tfh-B细胞相互作用的理解,并允许操纵文化条件调查潜在影响不同的微环境信号或配体/受体相互作用可能对Tfh细胞功能。
