  • Patent number: 11332538
    Abstract: Methods and compositions involving polypeptides having an aglycosylated antibody Fc domain are provided. In certain embodiments, polypeptides have an aglycosylated Fc domain that contains one or more substitutions compared to a native Fc domain. Additionally, some embodiments involve an Fc domain that is binds some Fc receptors but not others. For example, polypeptides are provided with an aglycosylated Fc domain that selectively binds C1q, and optionally activating Fc receptors, but that is significantly reduced for binding to the inhibitory Fc?RIIb receptor. Furthermore, methods and compositions are provided for promoting complement dependent cytotoxicity (CDC) using a polypeptide having a modified aglycosylated Fc domain and a second non-Fc binding domain, which can be an antigen binding region of an antibody or a non-antigen binding region. Some embodiments concern antibodies with such polypeptides, which may have the same or a different non-Fc binding domain.
