Preparation of human, humanized or chimaeric antibodies or polypeptides having different binding profiles to Fcgamma receptors

摘要

The present invention relates to a method for the production and the selection of human or chimæric or humanized antibodies or molecules that comprise the Fc region of human IgG, capable of modulating the activity of one or several particular Fc receptors, such as the triggering of inhibitory functions through the human type IIB receptors of IgG (FcgammaRIIB/CD32).
