The present disclosure relates to compositions and methods for compositions, methods, and kits for treating cancer using chimeric antigen receptor (CAR) modified cells. Some embodiments of the present disclosure relate to an isolated nucleic acid sequence encoding CAR. The CAR may include an antigen binding domain, a transmembrane domain, a costimulatory signaling region, and a CD3 zeta signaling domain. The antigen binding domain may bind to an antigen of a non-essential organ.

The present invention relates to nanoparticles for the targeted delivery of antigen to liver cells, in particular, liver sinusoidal endothelial cells (LSEC) and/or Kupffer cells, and for the in vivo generation of regulatory T cells, notably CD4+CD25+FOXP3+ regulatory T cells (Treg). The invention provides pharmaceutical compositions and methods for the prevention and treatment of autoimmune diseases, allergies or other chronic inflammatory conditions, and for generation of regulatory T cells. The nanoparticles used in the invention comprise a) a micelle comprising an amphiphilic polymer rendering the nanoparticle water-soluble, and b) a peptide comprising at least one T cell epitope associated with the outside of the micelle. The micelle may or may not comprise a solid hydrophobic core.

The present invention provides a peptide containing 8 or more consecutive amino acid residues in an amino acid sequence of any of SEQ ID NOS: 1 to 15 and consisting of 11 or less amino acid residues.

Described herein are methods comprising administering to a mammalian subject an effective amount of an annexin chimeric fusion protein, wherein the annexin chimeric fusion protein comprises at least one immunogenic antigen, thereby enhancing the antigen specific immune response relative to administration of the immunogenic antige alone. Methods and kits for treating or preventing recurrence of hyper proliferating diseases, e.g., cancer, are described. A method may comprise priming a mammal by administering to the mammal an effective amount of a chemotherapeutic agent and boosting the mammal by administering to the mammal an effective amount of an annexin chimeric fusion.

The present invention is directed toward methods of increasing the immune response to an antigen using TLR1/2 agonist and/or TLR7 agonist in combination with a T cell activating treatment, for example, a vaccine. In some aspects, the present invention provides methods of enhancing an anti-tumor response comprising administering at least one TLR1/2 agonist and/or at least one TLR7 agonist in combination with an immunotherapeutic agent.

In certain embodiments, this disclosure relates to conjugates comprising 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 comprising nucleic acid encoding polypeptide conjugates, and protein expression systems comprising these vectors such as infectious viral particles and host cells comprising such a nucleic acids.

The present invention discloses selective surfaces, wherein said selective surfaces comprise a biocompatible polymer comprising maleic anhydride molecules and an apoptosis inducing ligand bound to the maleic anhydride molecules. The invention also encompasses devices and kits comprising the selective surface and methods for its production. The selective surfaces may be used for functional selection of cell populations suitable for transplantation into human subjects.

Provided herein are NK-92 cells expressing at least one CAR and at least one Fc receptor. Also provided are methods of treatment of a patient having or suspected of having a disease that is treatable with NK-92 cells, such as cancer, comprising administering to the patient NK-92-Fc-CAR.

The disclosure relates to methods of treating or preventing a disease in a subject by conjointly administering to the subject an arginase inhibitor disclosed herein and a composition comprising immune cells disclosed herein.

Disclosed herein are engineered natural killer cells that have been modified to express chimeric antigen receptors (CARs). The cells optionally contain other modifications that improve tumor specific cytotoxicity and homing to tumor sites. Also contemplated are methods for using the engineered natural killer cells to treat patients with cancer.
