An established role of sphingosine 1-phosphate receptor-1 in T cells is to guide their exit from lymph nodes. Reporting in Nature, Mendoza et al. (2017) now show that lymphatic endothelial sphingosine 1-phosphate signals through sphingosine 1-phosphate receptor-1 to prevent mitochondria degradation and thereby support survival of naive T cells.
S1P 受体 1 在 T 细胞中的一个既定作用是引导它们从淋巴结中排出。门多萨等人在《自然》杂志上的报告(2017 年)现在表明,淋巴管内皮细胞的 S1P 通过 S1P 受体 1 发出信号,防止线粒体降解,从而支持幼稚 T 细胞的存活。
