Abstract: The present embodiments relate to methods of identifying and creating human or humanized antibodies that possess a reduced risk of inducing a Human Anti-Human Antibody (HAHA) response when they are applied to a human host. Other methods are directed to predicting the likelihood of a HAHA response occurring. Methods for screening for anti-HAHA compounds are also included. Methods for determining if various conditions for administering an antibody to a subject enhance or suppress a HAHA response are also included.

Abstract: The present invention provides fully human antibodies in a transgenic animal of a desired isotype in response to immunization with any virtually any desired antigen. The human immunoglobulin heavy chain transgene in the foregoing animals comprises a human constant region gene segment comprising exons encoding the desired heavy chain isotype, operably linked to switch segments from a constant region of a different heavy chain isotype, i.e., a non-cognate switch region. Said additional constant region segment comprises a switch region and human constant region coding segment, wherein the constant region coding segment is operably linked to a switch region that it is not normally associated with, i.e., a non-cognate switch region. In the transgenes of the invention, the non-cognate switch region may be a switch region from a different species than the constant region coding segment.
