簇细胞是罕见的化学感应上皮细胞,它们监测其环境并通过分泌神经和免疫调节分子将信息传递给周围组织。在小肠中,簇细胞检测蠕虫感染、原生生物定植和细菌失调,并启动以组织重塑为特征的 2 型免疫反应。在气道中,簇细胞感知细菌、过敏原和有害刺激,并驱动逃避行为、神经炎症和抗菌反应。在这里,我们总结了最新的簇细胞研究,并讨论这些发现如何提供对簇细胞多样性的深入了解。围绕化学传感核心程序构建,簇细胞受体和效应器功能根据周围组织的独特环境暴露和生理机能进行调整。
Tuft cells are rare chemosensory epithelial cells that monitor their environment and relay messages to the surrounding tissue via secretion of neuro- and immunomodulatory molecules. In the small intestine tuft cells detect helminth infection, protist colonization, and bacterial dysbiosis, and initiate a type 2 immune response characterized by tissue remodeling. In the airways, tuft cells sense bacteria, allergens, and noxious stimuli and drive evasive behavior, neuroinflammation, and anti-bacterial responses. Here we summarize the most recent tuft cell research and discuss how these findings have provided insight into tuft cell diversity. Built around a core program of chemosensing, tuft cell receptors and effector functions are tuned to the unique environmental exposure and physiology of their surrounding tissue.
