The soluble amino-terminal region of HVEM mediates efficient herpes simplex virus type 1 infection of gD receptor-negative cells

摘要

BackgroundPrevious studies from our own and other labs reported the surprising finding that the soluble V domain of the herpes simplex virus type 1 (HSV-1) entry receptor nectin-1 can both block HSV infection of receptor-bearing cells and mediate infection of receptor-deficient cells. Here we show that this property is not unique to nectin-1. We generated a pair of truncated, soluble forms of the other major HSV-1 entry receptor, herpes virus entry mediator (HVEM or HveA), and examined its effects on HSV-1 infection of receptor-deficient cells.
