小胶质细胞是中枢神经系统中一个精致的瓷砖和自包含的群体,不接受来自外周循环单核细胞的贡献。虽然小胶质细胞是长寿细胞,但其细胞体固定的程度以及调节小胶质细胞景观的分子机制尚未确定。使用慢性体内双光子成像,以遵循年轻成年小鼠的小胶质细胞群体,我们记录了每天的小胶质细胞景观重排。此外,我们表明,小胶质细胞景观可以调制严重癫痫发作,急性损伤,感觉剥夺。最后,我们证明了小胶质细胞P2Y12Rs在调节小胶质细胞景观通过独立于增殖的细胞易位的关键作用。这些结果表明,小胶质细胞巡逻中枢神经系统通过过程运动和索马易位。使用慢性体内成像方法,Eyo等人表明脑小胶质细胞的物理位置每天都在变化,并且这些变化在某些实验操作后增加。这些变化的机制涉及小胶质细胞特异性P2Y12受体控制的细胞易位。
Microglia are an exquisitely tiled and self-contained population in the CNS that do not receive contributions from circulating monocytes in the periphery. While microglia are long-lived cells, the extent to which their cell bodies are fixed and the molecular mechanisms by which the microglial landscape is regulated have not been determined. Using chronic in vivo two-photon imaging to follow the microglial population in young adult mice, we document a daily rearrangement of the microglial landscape. Furthermore, we show that the microglial landscape can be modulated by severe seizures, acute injury, and sensory deprivation. Finally, we demonstrate a critical role for microglial P2Y12Rs in regulating the microglial landscape through cellular translocation independent of proliferation. These findings suggest that microglial patrol the CNS through both process motility and soma translocation. Using a chronic in vivo imaging approach, Eyo et al. show that the physical positions of brain microglia change daily and that these changes increase following certain experimental manipulations. The mechanism underlying these changes involves cell translocation controlled by microglial-specific P2Y12 receptors.
