摘要

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.
