ANTIBODIES HAVING HUMANIZED FRAMEWORK REGIONS

The present disclosure provides binding agents, particularly, antibodies, that comprise variable regions comprising humanized framework regions. Nucleic acids that encode one or both of the variable chains of the binding agents of the present disclosure are also provided, as are cells that include such nucleic acids. Also provided are compositions, including in some instances, pharmaceutical compositions, that include the binding agents disclosed herein. Methods of making and using the binding agents of the present disclosure are also provided. In certain aspects, provided are methods that include administering to an individual having a cell proliferative disorder a therapeutically effective amount of a binding agent disclosed herein, where the binding agent is administered to the individual to enhance an immune response, e.g., a T cell response, to abnormally proliferating cells. The binding agents are also useful in various diagnostic, and monitoring applications, which are also provided.
