    摘要: The invention provides immunogenicity-reduced antibodies or antibody fragments that bind a human CR1 receptor. The immunogenicity-reduced anti-CR1 antibody of the invention comprises one or more non-human sequences modified to comprise one or more amino acid substitutions so that the immunogenicity-reduced antibody id non-immunogenic or less immunogenic to a human. The invention also provides bispecific molecules comprising such an immunogenicity-reduced anti-CR1 antibody and an antigen-recognition portion that binds a pathogen. The invention further provides methods and compositions for the treatment of diseases or disorders caused by a blood-borne immunogenic pathogen using the bispecific molecule the invention of the invention.

    摘要: The invention provides methods of using protein trans-splicing for the production of bispecific molecule which has a first antigen recognition portion that binds a C3b-like receptor and a second antigen recognition portion that binds an antigenic molecule present in the circulatory system of a mammal. The invention also provides bispecific molecules produced by protein trans-splicing. The bispecific molecules of the invention can be used for the clearance of pathogenic antigenic molecules from the circulatory system of a mammal. The invention further provides methods of using protein trans-splicing for the production of polyclonal libraries of bispecific molecules, which comprise populations of bispecific molecules with different antigen recognition specificities. Such polyclonal libraries of bispecific molecules can be used for targeting multiple epitopes of a pathogenic antigenic molecule and/or multiple variants of a pathogenic antigenic molecule.
