中心点:

在贫血的恢复过程中,单核细胞被招募到脾脏生成巨噬细胞,进而形成应激性红细胞壁龛。

单核细胞成熟形成巨噬细胞与应激性红系祖细胞发育平行发生。

摘要:

贫血应激会诱导一系列生理反应,包括快速产生新的红细胞,该过程被称为应激性红系发生。在小鼠中该过程很好理解,因为它发生在骨髓外,采用的信号和祖细胞不同与骨髓稳定状态的红系发生。应激性红系祖细胞的发育与脾脏应激性红细胞壁龛密切相关。特别是适度的应激性红系发生需要壁龛中的巨噬细胞参与。

研究人员发现随着应激性红系祖细胞的增殖和分化,壁龛的扩张也随之发生。在两种贫血应激模型中采用谱系示踪分析发现,脾脏壁龛扩张是由于单核细胞被招募到脾脏,随后变成巨噬细胞形成红细胞岛。单核细胞流入脾脏部分依赖于由Ccl2和脾脏常驻红髓巨噬细胞所表达的其他配体介导的Ccr2依赖性信号。

总而言之,本研究阐明了脾脏壁龛的动态特性,即在贫血应激的情况下,与应激性红系祖细胞一起迅速扩张,协调产生新的红细胞。
