[Abstract]  In vitro Th17 (α, β T helper cell which produce IL-17A, IL-17F and IL-22) differentiation has been routinely used for functional T cells studies. Here we describe a method for Th17 cell differentiation. [摘要]   Th17(产生IL-17A,IL-17F和IL-22的α,βT辅助细胞)分化已经常规用于功能性T细胞研究。 这里我们描述Th17细胞分化的方法。

[背景] T细胞 是介导宿主防御细菌,病毒和真菌以及共生的关键(Kumar等人,2016)。 T细胞可以基于它们产生特异性细胞因子的能力进一步细分为T辅助(Th1),Th2和Th17子集。 幼稚T细胞可以响应于特异性细胞因子刺激在体外培养中分化成特异性T细胞亚群。 体外产生的Th1,Th2和Th17细胞已经帮助我们理解它们的分化和它们的效应子功能的分子机制。 在这里,我们描述了Th17细胞生成的基本协议。

[Abstract]  Clearance of dead brain tissue including the dead neurons through phagocytosis is an endogenous function of microglia in the brain, which is critical for inflammation resolution after ischemic stroke or head trauma. By regulating the function or polarization status of microglia, we may control their phagocytosis efficacy and therefore the cleanup process for the dead brain tissue. We cultured rat cortical neurons and microglia from the same litter of embryos. The cultured neurons are subjected to irradiation for inducing neuronal apoptosis. After labeling with propidium iodide (PI), the dead neurons (DNs) are exposed to the cultured microglia for phagocytosis assay. By counting the number of DNs in each microglia, we calculate the phagocytosis index to quantify the phagocytosis efficacy ... [摘要]  通过吞噬作用来清除包括死亡神经元在内的死亡脑组织是脑中小胶质细胞的内源性功能,这对缺血性卒中或头部创伤后的炎症分解至关重要。通过调节小胶质细胞的功能或极化状态,我们可以控制其吞噬功效,从而控制死脑组织的清除过程。我们从相同的胚胎培养大鼠皮质神经元和小胶质细胞。培养的神经元经受辐射诱导神经细胞凋亡。用碘化丙啶(PI)标记后,将死亡神经元(DN)暴露于培养的小神经胶质细胞进行吞噬试验。通过计算每个小胶质细胞中的DN数量,我们计算吞噬指数,以量化小胶质细胞对DN的吞噬功效。方案分为4个部分:A)从产前大鼠胚胎培养大鼠皮质神经元,B)将死亡神经元作为吞噬作用靶标,C)培养大鼠脑小胶质细胞,D)定量小神经胶质细胞向死亡神经元的吞噬指数。
