Research Abstract

Panton-Valentine leukocidin (PVL) is a virulence factor of community-acquired methicillin-resistant Staphylococcus aureus. We have demonstrated the lipid raft-mediated pore formation of PVL. Since integrity of lipid rafts did not affect on the recognition of target cells by PVL, novel PVL receptor(s), other than ganglioside GM1, is suggested. This receptor molecule may be a possible target of PVL inhibitor.
