722-免疫与微生物组协同定义的干扰素稳态研究

from 聊聊Sci

这项发表在《Cell》上的研究通过对110名健康受试者进行多组学分析,揭示了人类免疫系统与肠道微生物群之间的紧密联系。研究人员发现了调节免疫差异的两个核心轴,其中免疫-微生物伴随变异轴 (IMCV) 尤为关键,它将特定的干扰素 (IFN) 反应信号与微生物代谢产物(如短链脂肪酸和多胺)联系在一起。这种由微生物驱动的免疫状态表现出高度的个体稳定性,并能有效预测接种疫苗后的免疫强度及癌症免疫疗法的临床效果。此外,研究还辨识出与此轴相关的特定细胞群,例如高表达 SIGLEC-1 的单核细胞和活化的记忆T细胞。这些发现不仅深化了对健康人体免疫稳态的理解,也为解析个体间疾病易感性和治疗反应的差异奠定了科研基础。References: Babdor J, Patel R K, Davidson B, et al.
