Beschreibung
Zusammenfassung:The inventions described herein are directed to bispecific antibodies that are capable of selectively targeting exosomes by specifically binding a first exosome-associated protein and Programmed Death Ligand-1 ("PD-L1") as a second exosome-associated protein. These bispecific antibodies can disrupt the suppression of anti-tumor activity by immune cells by targeting tumor-cell derived exosomes that inhibit T cell activation. Therefore, bispecific antibodies of the invention can be used in methods for treating cancers.
