我们每天都要转换数十亿个细胞。快速、有效和免疫学上沉默的死亡细胞处置需要多个步骤的协调配合,通过这些步骤,吞噬细胞选择性地识别和吞噬凋亡细胞。最近的研究表明,凋亡细胞释放的可溶性介质吸引吞噬细胞(“找到我”信号)的重要作用。新的信息也出现了多种受体,可以识别磷脂酰丝氨酸,关键的“吃我”信号暴露在凋亡细胞的表面。这个观点讨论了最近令人兴奋的进展,我们的理解差距,以及新获得的知识所产生的冲突问题。
Everyday we turnover billions of cells. The quick, efficient, and immunologically silent disposal of the dying cells requires a coordinated orchestration of multiple steps, through which phagocytes selectively recognize and engulf apoptotic cells. Recent studies have suggested an important role for soluble mediators released by apoptotic cells that attract phagocytes (“find-me” signals). New information has also emerged on multiple receptors that can recognize phosphatidylserine, the key “eat-me” signal exposed on the surface of apoptotic cells. This perspective discusses recent exciting progress, gaps in our understanding, and the conflicting issues that arise from the newly acquired knowledge.
