在本研究中, 我们提出了一个协议, 执行双光子活体成像和细胞相互作用分析的小鼠气管粘膜感染后流感病毒。这个协议将是相关的研究人员研究免疫细胞动力学在呼吸道感染。

这种方法可以帮助回答对空气传播病原体的免疫反应研究中关于呼吸道感染期间免疫细胞相互作用动力学的关键问题。该技术的主要优点是能够在整个简单手术过程中获得明亮稳定的气管上皮 4D 图像。虽然这种方法可以深入了解流感感染过程中中性粒细胞和裂解细胞的相互作用,但它也可以应用于不同免疫细胞或空气传播病原体的研究。

一般来说,刚接触这种方法的人将难以维持稳定和最小的炎症手术。此外,由于存在心脏缺陷,图像分析可能很棘手。对于鼻内流感感染,将麻醉的 6 至 8 周龄 CD11c-YFP 小鼠置于仰卧位,并通过对脚趾捏无反应来确认深度镇静。
