    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.

    摘要: The present invention provides liposomal compositions for inducing immune tolerance. The compounds typically comprise a liposome displaying a specific antigen and also a binding moiety for a sialic acid binding Ig-like lectin (Siglec)expressed on B cells. The invention also provides methods for inducing tolerance to a protein or polypeptide antigen (e.g., a protein antigen) in a subject. The methods involve administering to the subject a pharmaceutical composition that co-presents both the antigen and a glycan ligand for a Siglec expressed on B lymphocytes.
