The invention relates to the field of prophylaxis and therapy of cancer. Provided is a Indoleamine 2,3-dioxygenase (IDO) or peptide fragments hereof that are capable of eliciting anti-cancer immune responses. Specifically, the invention relates to the use of IDO or peptides derived herefrom or IDO specific T-cells for treatment of cancer. The invention thus relates to an anti-cancer vaccine which optionally may be used in combination with other immunotherapies and to IDO specific T-cells adoptively transferred or induced in vivo by vaccination as a treatment of cancer. The invention also provides that the medicaments herein provided may be used in combination with cancer chemotherapy treatment. The invention further provides the prophylaxis and therapy of infections by the same means as described above. The use of IDO and immunogenic peptide fragments hereof in cancer and infection treatment, diagnosis and prognosis is also provided.

Provided herein are polypeptide comprising a modified IL-2, wherein the modified IL-2 has reduced affinity for the IL-2 receptor relative to wild type IL-2. In some embodiments, polypeptides comprising a modified IL-2 that bind and agonize activated T cells are provided. Uses of the polypeptides comprising a modified IL-2 are also provided.

A pharmaceutical composition for enhancing radiation therapy, containing a fusion protein dimer is disclosed. The fusion protein dimer includes an IL-2 protein and a CD80 protein. A method of radiation therapy for cancer, using the composition is also disclosed. The composition for enhancing radiation therapy may increase the effect of radiation therapy in cancer treatment.

Disclosed herein are ACE2-Fc fusion polypeptides that contain at least one binding site for a spike protein of a coronavirus and methods of using such for therapeutic and/or diagnostic purposes. Also provided herein are methods for producing such fusion polypeptides.

Combination therapy of a cancer with a multi-specific binding protein that bind a tumor associated antigen, the NKG2D receptor, and CD16, in combination with a second anti-cancer agent are described. Also described are pharmaceutical compositions of the multi-specific binding protein, and therapeutic methods useful for the treatment of cancer in combination with a second anti-cancer agent.
