PD-L1 AND PD-L2-BASED FUSION PROTEINS AND USES THEREOF

摘要

Provided are fusion proteins comprising a first domain and a second domain, wherein the first domain comprises a polypeptide that binds to and triggers PD-1 and the second domain comprises a polypeptide that binds to and triggers a TRAIL receptor or Fas. In some embodiments, the polypeptide that binds to and triggers PD-1 comprises at least a portion of the extracellular domain of PD-L1 or PD-L2 and the second domain comprises at least a portion of the extracellular domain of TRAIL or Fas ligand. Also provided are methods for treating autoimmune, alloimmune or inflammatory diseases, and methods for treating cancer, using the fusion proteins.
