    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: A target protein is rendered less immunogenic to a given species by (a) determining at least part of the amino acid sequence of the target protein; (b) identifying in the amino acid sequence one or more potential epitopes for T-cells (“T-cell epitopes”) of the given species; and (c) modifying the amino acid sequence to eliminate at least one of the T-cell epitopes identified in step (b) to reduce the immunogenicity of the protein when exposed to the immune system of the given species.
