1157-干扰素刺激基因ISG全景抗病毒图谱研究

from 聊聊Sci

本文介绍了一项通过阵列化缺失功能筛选技术,系统性评估285种干扰素刺激基因 (ISGs) 对八种不同病毒影响的研究。研究人员利用延时活细胞成像平台,不仅确认了STAT1等具有广谱抗病毒作用的已知基因,还发现了如RTCB等具有广谱促病毒活性的基因。通过对协同作用的分析,研究揭示了抑制病毒进入的基因与参与信号传导的基因之间存在强烈的互补关系。特别地,该研究首次识别并阐明了BORCS8在对抗SARS-CoV-2中的关键地位,证明其通过调节早期内体酸化来降解病毒颗粒。利用机器学习中的自组织映射算法,研究者成功将功能相似的基因进行归类,揭示了先天免疫反应复杂的协同机制。最终,这套涵盖了蛋白质组学和相互作用组学的ISG图谱,为开发新型抗病毒疗法提供了宝贵的数据支持。References:Krey K, Risso-Ballester J, Hamad S, et al.
