Human Herpesvirus 6 Variant A Glycoprotein H-Glycoprotein L-Glycoprotein Q Complex Associates with Human CD46

Abstract excerpt

Human CD46 is a cellular receptor for human herpesvirus 6 (HHV-6). Virus entry into host cells requires a glycoprotein H (gH)-glycoprotein L (gL) complex. We show that the CD46 ectodomain blocked HHV-6 infection and bound a complex of gH-gL and the 80-kDa U100 gene product, designated glycoprotein Q, indicating that the complex is a viral ligand for CD46.
