Type I interferon receptor

Mouse studies suggest neutralizing interferon (IFN) receptor signaling could help treat persistent HIV or HCV infections. In mice infected with a persistent strain of lymphocytic choriomeningitis virus (LCMV), expression of IFN, proinflammatory cytokines and immunosuppressive factors was greater than that in mice infected with an acute LCMV strain. In mice with persistent LCMV infection, prophylactic or therapeutic treatment with an anti-IFN receptor antibody initially increased viral loads but decreased or eliminated the virus during the chronic phase of infection compared with isotype control treatment. Next steps include testing the strategy in human viral infections, including HIV.
