Ahmet Höke预览了Li及其同事的工作,表明化疗药物紫杉醇诱导的轴突变性是由Sarm1依赖性cADPR信号传导和钙流介导的。SARM 1的NAD水解酶结构域的激活介导化疗药物引起的轴突变性,但下游事件尚不清楚。本期,李和同事(2021. 202106080)证明cADPR(NAD的分解产物)通过促进钙流入轴突来介导紫杉醇诱导的轴突变性。
Ahmet Höke previews work from Li and colleagues that shows that the axonal degeneration induced by the chemotherapy agent paclitaxel is mediated by Sarm1-dependent cADPR signaling and calcium flux. Activation of the NAD hydrolase domain of Sarm1 mediates axonal degeneration caused by chemotherapy drugs, but the downstream events are unknown. In this issue, Li and colleagues (2021. J. Cell Biol. https://doi.org/10.1083/jcb.202106080) demonstrate that cADPR, a breakdown product of NAD, mediates paclitaxel-induced axonal degeneration by promoting influx of calcium into the axons.
