Molecular characterization of human monoclonal antibodies derived from fusions of tonsil lymphocytes with a human myeloma cell line

Exploring the native human antibody repertoire to create antiviral therapeutics

Native human antibodies are defined as those that arise naturally as the result of the functioning of an intact human immune system. The utility of native antibodies for the treatment of human viral diseases has been established through experience with hyperimmune human globulins. Native antibodies, as a class, differ in some respects from those obtained by recombinant library methods (phage or transgenic mouse) and possess distinct properties that may make them ideal therapeutics for human viral diseases. Methods for cloning native human antibodies have been beset by technical problems, yet many antibodies specific for viral antigens have been cloned. In the present review, we discuss native human antibodies and ongoing improvements in cloning methods that should facilitate the creation of novel, potent antiviral therapeutics obtained from the native human antibody repertoire.

Antibody discovery: the use of transgenic mice to generate human monoclonal antibodies for therapeutics

Technical advances made in the 1980s and early 1990s resulted in monoclonal antibodies that are now approved for human therapy. Novel transgenic mouse strains provide a powerful technology platform for creating fully human monoclonal antibodies as therapeutics; ten such antibodies have entered clinical trials since 1998 and more are in preclinical testing. Improved transgenic mouse strains provide a powerful technology platform for creating human therapeutics in the future.
