Nat Neurosci:小胶质细胞的依赖性随机或克隆扩增

研究首次揭示了在健康和疾病中枢神经系统中,成熟小胶质细胞动态的离散-组织周期

小胶质细胞构成一个高度专业化的组织驻留免疫细胞网络,对组织稳态的控制和中枢神经系统疾病的治疗至关重要,但小胶质细胞在体内如何建立和维持空间分布尚不清楚。近日,研究人员建立了一个新的多色荧光周期映射系统以监测小胶质细胞在稳态和疾病的动态情况。

研究发现,小胶质细胞建立一个密集的、区域差异的网络该网络呈现出快速的细胞代谢与更替,这与传统认为的小胶质细胞为长寿细胞相矛盾。在稳态条件下小胶质细胞自我更新是一个随机过程,在病理情况下,这种随机性转变为特定的小胶质细胞克隆扩张。在疾病缓解阶段,众多疾病相关的小胶质细胞通过细胞外排和凋亡的双重机制移除并重新建立稳定的小胶质细胞网络。

这项研究首次揭示了在健康和疾病中枢神经系统中,成熟小胶质细胞动态的离散-组织周期。
