FUSION PROTEINS OF PD-1 AND 4-1BB

The present invention relates to fusion proteins comprising (a) an extracellular domain containing a polypeptide derived from PD-1 or CD40L at its N-terminus; (b) a transmembrane domain; and (c) an intracellular domain containing a polypeptide derived from 4-1BB or CD28 at its C-terminus. Also, fusion proteins with CD28 at the N-terminus and CD40L at the C-terminus are envisaged. The present invention also relates to nucleic acid molecules encoding such fusion proteins, vectors containing such nucleic acid molecules, and host cells containing such vectors. The present invention further relates to methods for producing such host cells. Finally, the present invention relates to pharmaceutical compositions comprising such fusion proteins, nucleic acid molecules, vectors, and/or host cells, particularly for treating diseases or disorders associated with PD-1/PD-L2 or CD40 binding and/or PD-L1/PD-L2 or CD40 expression such as cancer and chronic viral infection.
