MR1限制性T细胞(MR1T)是识别和介导宿主对广泛的微生物病原体(包括呼吸道病原体(例如,结核分枝杆菌、化脓性链球菌和土拉弗朗西斯菌)和肠道病原体(例如,大肠杆菌和沙门氏菌属)。粘膜相关不变T(MAIT)细胞是MR1T的一个子集,历史上通过使用半不变T细胞受体(TCR)和识别来自MR1上核黄素生物合成途径的小分子来定义。我们使用质谱法鉴定来自微生物E.大肠杆菌和耻垢分枝杆菌。我们发现MR1配体组出乎意料地广泛,揭示了来自大肠杆菌的功能不同的配体。coli和M.恶臭分枝杆菌配体的鉴定、合成和功能分析表明,MR1T配体可以通过具有不同TCR用途的MR1T来区分。这些数据表明,MR1可以作为微生物配体组的免疫传感器。
MR1-restricted T cells (MR1Ts) are a T cell subset that recognize and mediate host defense to a broad array of microbial pathogens, including respiratory pathogens (e.g., Mycobacterium tuberculosis, Streptococcus pyogenes, and Francisella tularensis) and enteric pathogens (e.g., Escherichia coli and Salmonella species). Mucosal-associated invariant T (MAIT) cells, a subset of MR1Ts, were historically defined by the use of a semi-invariant T cell receptor (TCR) and recognition of small molecules derived from the riboflavin biosynthesis pathway presented on MR1. We used mass spectrometry to identify the repertoire of ligands presented by MR1 from the microbes E. coli and Mycobacterium smegmatis. We found that the MR1 ligandome is unexpectedly broad, revealing functionally distinct ligands derived from E. coli and M. smegmatis. The identification, synthesis, and functional analysis of mycobacterial ligands reveal that MR1T ligands can be distinguished by MR1Ts with diverse TCR usage. These data demonstrate that MR1 can serve as an immune sensor of the microbial ligandome.
