708-Foli-seq:粪便脱落组测序捕捉肠道免疫动态

from 聊聊Sci

这篇文章介绍了一种名为 Foli-seq 的创新型非侵入式肠道检测技术,发表于 2025 年的《自然·生物技术》。该技术通过对粪便中脱落的宿主细胞 mRNA(feRNA) 进行高通量测序,成功克服了样本降解与微生物干扰等技术难题。研究证明,Foli-seq 能够精准捕捉肠道内的免疫动态和组织损伤,其效果与侵入性的结肠镜活检具有高度相关性。在小鼠模型中,它能灵敏追踪炎症性肠病(IBD)的病理过程及药物疗效;而在人体临床试验中,该技术成功将患者划分为反映不同疾病严重程度的免疫亚型。此外,该研究还通过同步分析粪便外显体与微生物组,揭示了宿主与肠道菌群之间复杂的交互网络。总之,Foli-seq 为胃肠道健康的长期纵向监测提供了一种安全、高效且低成本的数字化新方案。References: Huang Y, Sun Y, Ronda C, et al.
