Research Abstract

Human scavenger receptor class B member 2 (SCARB2) and P-selectin glycoprotein ligand-1 (PSGL-1) have been reported te be receptors for enterovirus 71. I functionally compared these receptors. Enterovirus 71 infects more efficiently via SCARB2 than PSGL-1. The binding affinity of PSGL-1 to viral particles is stronger than that of SCARB2. The conformational alteration of enterovirus 71 is triggered by incubation with SCARB2 under acidic conditions but not by incubation with PSGL-1 under any condition which we tested.
These data suggest that SCARB2 is an authentic receptor for enterovirus 71 and PSGL-1 may act as an attachment molecule for enterovirus 71 on the cell surface.
