USING B-CELL-TARGETING ANTIGEN IgG FUSION AS TOLEROGENIC PROTEIN THERAPY FOR TREATING ADVERSE IMMUNE RESPONSES

摘要

The present invention generally relates to antigen-specific tolerogenic protein therapy and the use thereof for treating adverse immune responses, including those associated with autoimmune diseases such as multiple sclerosis (MS) and hemophilia. In particular, the invention involves the application of a B cell-targeting IgG fusion protein as the antigen-specific tolerogenic protein therapy, either alone or in combination with inhibitory antibodies. The fusion protein comprises a B-cell specific targeting module, the constant region of the human IgG4 heavy chain or a fragment thereof; and an antigen.
