PD-L1 TARGETING MOLECULES COMPRISING SHIGA TOXIN A SUBUNIT SCAFFOLDS

Abstract:

Provided herein are PD-L1 binding molecules comprising Shiga toxin A Subunit derived polypeptides and methods of using the same. Certain PD-L1 targeting molecules embodiments are cytotoxic. Certain PD-L1 targeting molecules embodiments exhibit reduced immunogenic potential in mammals and/or are capable of delivering an immunogenic epitope to an MHC class I molecule of a PD-L1 positive cell. Certain PD-L1 targeting molecules embodiments are well-tolerated by mammals while retaining one or more of the features mentioned above. The PD-L1 targeting molecules have uses for selectively killing specific cells (e.g., PD-L1 positive tumor and/or immune cells); for selectively delivering cargos to specific cells (e.g., PD-L1 positive tumor and/or immune cells), and as therapeutic and/or diagnostic molecules for treating and diagnosing a variety of conditions, including cancers and tumors involving PD-L1 expressing cells.
