Herpesvirus entry mediator (HVEM) is a type I membrane protein in the TNF receptor superfamily; and it can both promote and inhibit T cell activity. HVEM is highly expressed on na?ve CD4+ T cells; CD8+ T memory cells; regulatory T cells; dendritic cells; monocytes; and neutrophils. It functions as a receptor for BTLA; CD160; LIGHT/TNFSF14; and Lymphotoxin-alpha. Ligation of HVEM by LIGHT triggers T cell; monocyte; and neutrophil activation and contributes to Th1 inflammation and cardiac allograft rejection. In contrast; HVEM binding to CD160 or BTLA suppresses T cell and dendritic cell activation and dampens intestinal inflammation. HVEM enhances the development of CD8+ T cell memory and Treg function. It is additionally expressed on intestinal epithelial cells; where its binding by intraepithelial lymphocyte (IEL) expressed CD160 promotes epitheilal integrity and host defense. The herpesvirus envelope glycoprotein gD; which binds HVEM to initiate membrane fusion; can antagonize both BTLA and LIGHT binding.
