在这里,我们描述了一种基于显微镜的技术,用于可视化和量化病原体吞噬过程中事件的早期级联反应,例如真菌白色念珠菌和大于 0.5 μm 的颗粒,包括酵母聚糖和 IgG 包被的珠子。

该技术的总体目标是使用共聚焦显微镜监测吞噬作用的不同阶段。这种方法可以帮助回答交叉病原体相互作用领域的关键问题。主要是为了了解病原体在感染过程中如何进入宿主细胞。

这种技术的主要优点是它很简单,使我们能够以时间敏感的方式获得有关吞噬作用过程中发生的事件的病毒细胞的信息。首先,按照随附文本方案中的说明准备荧光偶联的酵母聚糖。前一天,在腔室载玻片中接种约 5 乘以 10 至第四个 DC 2.4 细胞,以便在实验时孔达到 60% 至 70% 汇合。
