title: Equine herpesvirus 1 utilizes a novel herpesvirus entry receptor.
abstract: The well-described herpesvirus entry receptors HveA (TNFRSF14), HveB (nectin 2), and HveC (nectin 1) have been shown to mediate the entry of alphaherpesviruses. Our findings showed that the alphaherpesvirus equine herpesvirus 1 (EHV-1) efficiently entered and replicated in CHO-K1 cells that lack the entry receptors HveA, HveB, and HveC, demonstrating that EHV-1 utilizes a unique entry receptor. As with other alphaherpesviruses, efficient EHV-1 entry was dependent on glycoprotein D and cell surface glycosaminoglycans.
