620. 牛久病毒:揭示生命起源的新型巨型病毒
from 知为谁 · host 知为谁
这项研究介绍了一种在物理上十分巨大的新病毒——牛久病毒(Ushikuvirus),它是在日本牛久湖被发现的。由于这种病毒能够感染变形虫并改变其细胞结构,科学家认为它为研究真核细胞内核的起源提供了关键证据。该发现支持了“病毒真核生物发生”假说,即细胞核可能演化自古代的大型DNA病毒。牛久病毒具有独特的表面突刺,并在复制过程中会破坏宿主的核膜,这揭示了巨型病毒演化的多样性。研究人员指出,深入了解这些病毒不仅能探索生命起源的奥秘,未来还可能为治疗由变形虫引起的疾病提供新策略。通过对比不同巨型病毒的特征,这项工作进一步填补了生命进化树中病毒与复杂生物之间的空白。内容来源:https://www.tus.ac.jp/en/mediarelations/archive/20251219_9539.html
