1315-全细胞线粒体动力学数字孪生模拟
from 聊聊Sci
这篇论文介绍了一种全细胞数字孪生模拟框架,该框架将4D晶格光片显微镜(LLSM)获取的活细胞数据与粒子反应扩散模拟相结合。研究人员通过该技术精确模拟了线粒体在细胞内的动态行为,包括它们在微管网络上的主动运输、融合与裂变。该模型无需重新调整参数即可成功预测线粒体对药物诱导微管干扰的反应,展示了极强的预测能力。此外,模拟揭示了微管拓扑结构(而非仅仅是马达蛋白动力学)是驱动线粒体向核周聚集的关键结构闸门。这项工作为在生物学背景下探索复杂的细胞内动力学提供了一个可解释且具备力学基础的计算平台。References:Arkfeld E, Wang Z, Hakozaki H.
