Antibody and inhibitor, and transfection method or kit using them

摘要

The present invention provides a monoclonal antibody which specifically binds to human Toll-like receptor 3 and inhibits production of type 1 interferon. It also provides an inhibitor which (a) suppresses a double-stranded RNA-mediated immune response in a cell which expresses Toll-like receptor 3 that recognizes the double-stranded RNA and produces type I interferon, and (b) includes an antibody, which binds to the Toll-like receptor 3 and inhibits production of the type I interferon. Particularly, the monoclonal antibody is against human Toll-like receptor 3. Further, a transfection method and kit are provided. Production of type I interferon can be controlled by using an antibody which specifically binds to Toll-like receptor 3 that recognizes a double-stranded RNA and produces type I interferon.
