Listeriolysin O, but not Murine E-cadherin, is Involved in Invasion of Listeria monocytogenes into Murine Liver Parenchymal Cells.
Human E-cadherin and listeriolysin O (LLO) are involved in invasion of Listeria monocytogenes into human liver parenchymal cells (LPC). Yet, it remains to be determined whether murine E-cadherin and LLO participate in invasion of L. monocytogenes into murine LPC. In the present study, involvement of murine E-cadherin and LLO in invasion of L. monocytogenes into murine LPC was investigated. Murine E-cadherin was expressed on murine LPC, but the expression became undetectable by insertion of transgene of Simian virus 40 large T antigen. Although invasion of L. monocytogenes into murine LPC was found regardless of murine E-cadherin expression, infection rate of L. monocytogenes being unable to secrete LLO was lower than that of L. monocytogenes being capable of secreting LLO. Our RESULTS verify that invasion of L. monocytogenes into murine LPC occurs independently of murine E-cadherin and indicate that LLO participates in invasion of L. monocytogenes into murine LPC.
