Technology provided herein relates to methods of treating cancer comprising administering to a subject in need thereof a first stem cell (SC) modified to release an oncolytic virus and a second SC which is gene edited to inactivate a receptor for the oncolytic virus, thereby generating a stem cell resistant to the virus, wherein the second SC is also engineered to express an immunomodulatory polypeptide agent. Compositions comprising a first and second SC, and uses thereof, are also provided herein.

The present disclosure is directed to the combination of a Fas axis antagonist, such as an anti-FasL antibody, and a Treg cell depletion therapy, for example an anti-CD25 antibody, optionally with a cancer vaccine, for use in the treatment of cancer.

In certain embodiments, this disclosure relates to conjugates including GM-CSF and IL-7 and uses related thereto, e.g., enhancing the adaptive immune system. Typically, the GM-CSF and IL-7 are connected by a polymer linker, e.g., polypeptide. In certain embodiments, the disclosure relates to nucleic acids encoding these polypeptide conjugates, vectors including nucleic acid encoding polypeptide conjugates, and protein expression systems including these vectors such as infectious viral particles and host cells including such nucleic acids.
