纤维母细胞网状细胞(FRC)是淋巴器官的免疫学专门成纤维细胞,而FRC成熟对于淋巴结(LNs)的结构和功能特性至关重要。 在这里,我们显示HAP信号的最终效应器YAP和TAZ(YAP / TAZ)调节FRC的参与和成熟。

 

YAP/TAZ在FRCs中的选择性消耗会损害FRC的生长和分化并损害LN的结构组织,而YAP/TAZ的过度活化会增强FRCs的肌成纤维细胞特征并加重LN纤维化。机制上,YAP/TAZ和p52之间的相互作用促进了趋化因子表达,这是在淋巴毒素β受体(LTβR)参与之前进行FRC谱系定位所需的趋化因子表达,而LTβR激活抑制了FAP成熟的YAP/TAZ活性。

 

因此,我们的发现将YAP/TAZ视为FRC承诺和成熟的关键调节剂,并有望更好地了解FRC介导的病理生理过程。
