B细胞发育的突破口
在B细胞发育过程中,免疫球蛋白基因的组装以有序波的形式发生。重链(Igh)位点通常首先重组,每个等位基因最多有一次机会进行生产性重排。随后,在κ (Igk)位点,单个等位基因可以进行连续的重排,允许不同的轻、重链组合进行测试,直到产生功能性的、非自我反应性的免疫球蛋白。这两波重组被一个由前b细胞受体(pre-BCR)控制的检查点分开,该检查点强制在Igh位点排除等位基因,触发增殖,并促进Igk重排。这就提出了一个问题:如果DNA切割和细胞周期进入同时开始,我们如何减轻可能发生的基因组损伤?在这期杂志上,Bednarski等人提出了一个解决方案:ragg诱导的DNA双链断裂(DSBs)抑制bcr前信号传导的一种意想不到的机制。rag诱导的dsb触发一个信号通路,最终通过转录抑制子SPIC抑制bcr前信号。
