ABSTRACT
@#Abstract: Type I interferons play an important role in the pathogenesis of autoimmune diseases such as systemic lupus erythematosus (SLE). Monoclonal antibody shows therapeutic potential by blocking the signaling pathway. This study used recombinant human subunit 1 of the type I interferon receptor (IFNAR1) protein to immunize New Zealand white rabbits, and applied B cell cloning technology to screen and obtain rabbit parental antibodies. After humanization modification, QX006N was obtained. In vitro biological studies showed that QX006N could specifically bind to human IFNAR1 with an affinity of 108 pmol/L, and neutralize the type I interferon signaling pathway and this pathway mediated biological effects. This study provides a solid foundation for the development of antibody drugs targeting the type I interferon signaling pathway for the treatment of SLE.
