The disclosure relates to compositions and methods for the preparation, manufacture and therapeutic use of combinations of immunomodulatory polynucleotides (e.g., mRNAs) encoding an immune response primer polypeptide (e.g., an interleukin 23 (IL-23) polypeptide or an interleukin 36γ (IL-36-gamma) polypeptide), and an immune response co-stimulatory signal polypeptide (e.g., an OX40L polypeptide).

In one embodiment, the present disclosure provides an engineered cell having a first chimeric antigen receptor polypeptide including a first antigen recognition domain, a first signal peptide, a first hinge region, a first transmembrane domain, a first co-stimulatory domain, and a first signaling domain; and a second chimeric antigen receptor polypeptide including a second antigen recognition domain, a second signal peptide, a second hinge region, a second transmembrane domain, a second co-stimulatory domain, and a second signaling domain; wherein the first antigen recognition domain is different than the second antigen recognition domain.

Cancer is treated using coordinated treatment regimens that uses various compounds and compositions that drive a tumor from the escape phase of cancer immunoediting to the elimination and equilibrium phase of cancer immunoediting.

The present disclosure relates to systems and methods for immune therapy. For example, a method can be used to enhance proliferation of chimeric antigen receptor (CAR) T cells in a patient, The method comprises administering to the patient an effective amount of a pharmaceutical composition comprising lymphocyte activation agents and one or more recombinant viral particles comprising a polynucleotide encoding a CAR, wherein the proliferation of CAR T cells in the patient is greater as compared to a patient administered with the one or more recombinant viral particles but without the lymphocyte activation agents.

Implantable scaffolds that treat solid tumors and escape variants and that provide effective vaccinations against cancer recurrence are described. The scaffolds include genetically-reprogrammed lymphocytes and a lymphocyte-activating moiety.
