细菌内毒素（Ｌｉｐｏｐｏｌｙｓａｃｃｈａｒｉｄｅ，ＬＰＳ）通过分布在细胞表面的ＬＰＳ受体将其信号传递至细胞内，引发一系列胞内事件，最终激活细胞。本文就近年来对ＬＰＳ信号受体及ＬＰＳ信号的跨膜转导机制的研究进展作一综述 Lipopolysaccharide (LPS) signals its distribution to cells via LPS receptors distributed on the cell surface, triggering a series of intracellular events that ultimately activate the cell. This review summarizes the research progress of transmembrane transduction mechanism of LPS signaling and LPS signaling in recent years
