Efferocytosis, 凋亡细胞的吞噬去除, 是需要保持动态平衡, 并由受体和信号通路, 以允许识别, 吞没和内化的凋亡细胞的促进。在此, 我们提出了一个荧光显微镜协议的量化 efferocytosis 和 efferocytic 信号通路的活动。

该方法可用于回答胞吐作用领域的关键问题,例如信号分子在介导凋亡细胞摄取中的作用。该技术的主要优点是它提供了凋亡细胞摄取的明确定量,包括部分或零碎的凋亡细胞摄取,这在其他方法中并不总是很明显。虽然这种方法可以深入了解免疫细胞的胞吐作用,但它也可以应用于其他细胞类型,例如上皮细胞或癌细胞。

通常,由于难以优化显微镜采集设置,刚接触这种方法的人会遇到困难。制备人巨噬细胞和凋亡的 Jurkat 细胞后,使用血细胞计数器对凋亡细胞进行计数。然后将足够量的凋亡细胞转移到 1.5 mL 微量离心管中。
