    摘要: The present invention provides immune conjugates for inducing antigen specific immune tolerance to coagulation Factor VIII. The immune conjugates contain a FVIII protein or antigenic fragment that is conjugated to a binding moiety for a sialic acid binding Ig-like lectin (Siglec) expressed on B cells. The invention also provides methods of using the FVIII immune conjugates to induce immune tolerance to FVIII in a subject. Additionally provided in the invention are methods for treating bleeding disorders such as hemophilia A via the use of the FVIII immune conjugates and an unconjugated FVIII with coagulating activity.
