Abstract
The hallmarks of persistent viral infections are exhaustion of virus-specific T cells, elevated production of interleukin 10 (IL-10) and programmed death-1 (PD-1) the dominant negative regulators of the immune system and disruption of secondary lymphoid tissues. Within the first 12-24 hours after mice are infected with lymphocytic choriomeningitis virus (LCMV) clone 13, which is used as a model of persistent virus infection, we note generation of high titers of type 1 interferon. Blockade of type 1 interferon significantly lessens IL-10 and PD-1/PD-L1, allows normal secondary lymphoid architecture and re-establishes antiviral T-cell function, thus eradicating the virus and clearing the infection. Hence, type 1 interferon is a master reostat for establishing persistent viral infection.Entities:
