我们描述了一种测量感染或不感染人类免疫缺陷病毒 (HIV) 1 型的活细胞中吞噬体向细胞中心移动速度的方法,使用转盘共聚焦荧光显微镜识别荧光感染细胞和明场显微镜检测吞噬体。

该分析的总体目标是使用简单的手动跟踪方法量化 HIV-1 感染的巨噬细胞中的吞噬体速度。该协议的优点是提供了一种简单的方法来计算单元内可以移动或变形的物体组的相对运动。这种方法提供了对 GFP 阳性感染巨噬细胞中吞噬体运动的见解,但它可用于荧光标记细胞中的其他细胞间区室。

在感染人单核细胞衍生的巨噬细胞并调理绵羊繁殖的血细胞后,根据文本方案,使用共聚焦成像系统(例如旋转盘显微镜)设置吞噬作用测定,该系统配备了 37 摄氏度的加热室,含有二氧化碳。在实验之前,打开加热室将显微镜载物台加热到 37 摄氏度。然后打开显微镜和计算机,并加载成像软件。
