Endothelial Cells Support Persistent Gammaherpesvirus 68 Infection
A variety of human diseases are associated with gammaherpesviruses, including neoplasms of lymphocytes (e.g. Burkitt's lymphoma) and endothelial cells (e.g. Kaposi's sarcoma). Gammaherpesvirus infections usually result in either a productive lytic infection, characterized by expression of all viral genes and rapid cell lysis, or latent infection, characterized by limited viral gene expression a...
متن کاملCD4 T cells mediate killing during persistent gammaherpesvirus 68 infection.
CD4 T cells are critical for the control of gammaherpesvirus persistence, but their direct effector mechanisms of virus control in vivo are still poorly understood. In this study, we use murine gammaherpesvirus 68 (gammaHV68) in in vitro and in vivo cytotoxicity assays to show CD4-dependent killing of gammaHV68-loaded cells in mice persistently infected with gammaHV68. Our results underscore th...
متن کاملGlycosaminoglycan Interactions in Murine Gammaherpesvirus-68 Infection
Glycosaminoglycans (GAGs) commonly participate in herpesvirus entry. They are thought to provide a reversible attachment to cells that promotes subsequent receptor binding. Murine gamma-herpesvirus-68 (MHV-68) infection of fibroblasts and epithelial cells is highly GAG-dependent. This is a function of the viral gp150, in that gp150-deficient mutants are much less GAG-dependent than wild-type. H...
متن کاملB cells regulate murine gammaherpesvirus 68 latency.
The dynamics of the establishment of, and reactivation from, gammaherpesviruses latency has not been quantitatively analyzed in the natural host. Gammaherpesvirus 68 (gammaHV68) is a murine gammaherpesvirus genetically related to primate gammaherpesviruses that establishes a latent infection in infected mice. We used limiting dilution reactivation (frequency of cells reactivating gammaHV68 in v...
متن کاملInvolvement of TLR2 in Recognition of Acute Gammaherpesvirus-68 Infection
BACKGROUND Toll-like receptors (TLRs) play a crucial role in the activation of innate immunity in response to many viruses. We previously reported the implication of TLR2 in the recognition of Epstein-Barr virus (EBV) by human monocytes. Because murine gammaherpesvirus-68 (MHV-68) is a useful model to study human gammaherpesvirus pathogenesis in vivo, we evaluated the importance of mouse TLR2 i...
