摘要:
The present invention provides molecules, including IgGs, non-lgG immunoglobulins, proteins and non-protein agents, that have increased in vivo half-lives due to the presence of an IgG constant domain, or a portion thereof that binds the FcRn, having one or more amino acid modifications that increase the affinity of the constant domain or fragment for FcRn. Such proteins and molecules with increased half-lives have the advantage that smaller amounts and or less frequent dosing is required in the therapeutic, prophylactic or diagnostic use of such molecules.

摘要:
The present invention relates to methods and compositions designed for the treatment, management, prevention and/or amelioration of various disorders associated with aberrant expression and/or activity of one or more Eph receptor tyrosine kinase family members and/or one or more Eph receptor ligands, particularly the ephrins. In particular, the invention provides methods for the treatment, management, prevention and/or amelioration of a disorder associated with aberrant expression and/or activity(ies) of one or more Eph receptors and/or one or more ephrins, the method comprising administering to a subject in need thereof an effective amount of one or more Eph/ephrin modulators. The present invention further relates to methods of modulating antibody specificity by tailoring the affinity to cognate antigens.
摘要:
The present invention provides polypeptides containing at least the FcRn binding portion of an Fc region of an immunoglobulin molecule and that have altered amino acid sequences relative to wild type immunoglobulin molecules. The polypeptides have decreased in vivo serum half-lives and can be employed in various methods.
