766. 肠癌关联新发现:肠道细菌病毒研究

from 知为谁 · host 知为谁

南丹麦大学的研究人员在一种常见的肠道细菌中发现了一种此前未被描述的病毒,该病毒与结直肠癌的发病风险存在显著的统计学关联。虽然这种名为拟杆菌的细菌普遍存在于健康人体内,但癌症患者的细菌样本中更有可能携带这种特定的噬菌体。这项研究跨越了丹麦本土及国际大型数据集,涵盖了来自全球近九百名受试者的样本分析。目前,专家们正致力于探究该病毒是直接致病的诱因,还是肠道环境改变的信号。未来,这一发现有望转化为粪便筛查技术,通过检测特定病毒序列来实现癌症的早期风险评估与预防。该团队正通过人工肠道模型和动物实验进一步揭示病毒、细菌与肿瘤组织之间的相互作用。
