在发育重塑过程中,预定修剪的神经突常在原位退化。身体损伤也会导致损伤部位远端神经突变性。迅速清除退化的轴突对于维持组织内环境稳定和防止炎症反应非常重要。在这里,我们发现在果蝇感觉神经元的树突修剪和树突损伤中,表皮细胞而不是血细胞是清除退化树突的主要吞噬细胞。表皮细胞通过Draper介导的识别作用促进树突退化,并吞噬和降解退化的树突。利用多树突状细胞膜标记追踪吞噬作用,我们发现CD36家族的两个成员,croquemort(CRQ)和DSB(DSB),在吞噬小体成熟的不同阶段作用于树突清除。我们的发现揭示了神经元与其周围的表皮之间的协调对于树突的碎裂和清除具有重要的生理意义。
During developmental remodeling, neurites destined for pruning often degenerate on-site. Physical injury also induces degeneration of neurites distal to the injury site. Prompt clearance of degenerating neurites is important for maintaining tissue homeostasis and preventing inflammatory responses. Here we show that in both dendrite pruning and dendrite injury of Drosophila sensory neurons, epidermal cells rather than hemocytes are the primary phagocytes in clearing degenerating dendrites. Epidermal cells act via Draper-mediated recognition to facilitate dendrite degeneration and to engulf and degrade degenerating dendrites. Using multiple dendritic membrane markers to trace phagocytosis, we show that two members of the CD36 family, croquemort (crq) and debris buster (dsb), act at distinct stages of phagosome maturation for dendrite clearance. Our finding reveals the physiological importance of coordination between neurons and their surrounding epidermis, for both dendrite fragmentation and clearance.
