The impact of Listeria monocytogenes listeriolysin O (LLO) secretion on phosphoinositide metabolism and mediator (platelet-activating factor and prostaglandin I2) generation was investigated in human umbilical vein endothelial cells. Wild-type L. monocytogenes, purified LLO, and an L. innocua strain engineered to secrete LLO all elicited a strong response, whereas mutant strains defective in LLO production were ineffective. Thus, human umbilical vein endothelial cell stimulation by listeriae is linked to production of LLO.
在人脐静脉内皮细胞中研究了单核细胞增生李斯特菌溶血素O(LLO)分泌对磷酸肌醇代谢和介质(血小板活化因子和前列腺素I2)生成的影响。野生型单核细胞增生李斯特菌、纯化的LLO以及经基因工程改造以分泌LLO的无害李斯特菌菌株均引发了强烈反应,而LLO产生缺陷的突变菌株则无效。因此,李斯特菌对人脐静脉内皮细胞的刺激与LLO的产生有关。
