淋巴结节(LN)是启动免疫反应的地方,由成纤维细胞网状细胞(FRC)组织成不同的间隔。FRCS通过支持LN结构、招募免疫细胞、协调免疫细胞串扰和呈递抗原来印记免疫反应。最近的高分辨率转录和组织学分析丰富了我们对LN FRC遗传和空间异质性的了解。在这里,我们总结了FRC亚群的最新解剖学、表型和功能特性,深入研究了FRC在炎症中的拓扑和转录重构,并阐明了FRC和免疫细胞之间的串扰。讨论了FRC在免疫和耐受中的作用,重点介绍了基于FRC的最新治疗方法,用于维持生理动态平衡、引导保护性免疫、诱导移植耐受和治疗各种免疫相关疾病。
Lymph nodes (LNs), where immune responses are initiated, are organized into distinctive compartments by fibroblastic reticular cells (FRCs). FRCs imprint immune responses by supporting LN architecture, recruiting immune cells, coordinating immune cell crosstalk, and presenting antigens. Recent high-resolution transcriptional and histological analyses have enriched our knowledge of LN FRC genetic and spatial heterogeneities. Here, we summarize updated anatomic, phenotypic, and functional identities of FRC subsets, delve into topological and transcriptional remodeling of FRCs in inflammation, and illustrate the crosstalk between FRCs and immune cells. Discussing FRC functions in immunity and tolerance, we highlight state-of-the-art FRC-based therapeutic approaches for maintaining physiological homeostasis, steering protective immunity, inducing transplantation tolerance, and treating diverse immune-related diseases.
