Innate lymphoid cells (ILC) play critical roles in regulating immunity, inflammation, and tissue homeostasis in mice. However, limited access to non-diseased human tissues has hindered efforts to profile anatomically-distinct ILCs in humans. Through flow cytometric and transcriptional analyses of lymphoid, mucosal, and metabolic tissues from previously healthy human organ donors, here we have provided a map of human ILC heterogeneity across multiple anatomical sites. In contrast to mice, human ILCs are less strictly compartmentalized and tissue localization selectively impacts ILC distribution in a subset-dependent manner. Tissue-specific distinctions are particularly apparent for ILC1 populations, whose distribution was markedly altered in obesity or aging. Furthermore, the degree of ILC1 population heterogeneity differed substantially in lymphoid versus mucosal sites. Together, these analyses comprise a comprehensive characterization of the spatial and temporal dynamics regulating the anatomical distribution, subset heterogeneity, and functional potential of ILCs in non-diseased human tissues.

人类先天淋巴细胞的空间和时间映射揭示了组织特异性的要素。

先天性淋巴样细胞 (ILC) 在调节小鼠免疫、炎症和组织稳态方面发挥着关键作用。然而,对非患病人体组织的有限获取阻碍了对人类解剖学上不同的 ILC 进行分析的努力。通过对以前健康的人体器官供体的淋巴、粘膜和代谢组织进行流式细胞术和转录分析,我们在这里提供了跨越多个解剖部位的人类 ILC 异质性图谱。与小鼠相比,人类 ILC 的划分不那么严格,组织定位以子集依赖的方式选择性地影响 ILC 分布。组织特异性差异对于 ILC1 人群尤为明显,其分布在肥胖或衰老过程中发生显着变化。此外,ILC1 种群异质性的程度在淋巴和粘膜部位有很大差异。总之,这些分析包括对调节非患病人体组织中 ILC 的解剖分布、子集异质性和功能潜力的时空动态的综合表征。
