Production and use of novel therapeutic cells, called T-Vehicles, in the allogeneic Adoptive Cell Therapy setting allows a wide range of therapeutic benefits to accrue with minimal or no risk of GVHD. T-Vehicles are created from donor T cells that are altered to contain therapeutic attributes that do not include their native antigen receptors and can deliver therapeutic benefits irrelevant of their native antigen specificity. T-Vehicles can possess highly restricted native antigen specificity that renders them unable to recognize antigens present on normal cells and incapable of initiating GVHD, making them ideal transport vehicles to deliver various therapeutic attributes in vivo. In essence, production and use of T-Vehicles is a paradigm shift that opens the door to therapeutic application of T cells in ways not previously contemplated, independent of whether or not there is an HLA match between the donor and the recipient.

The present application provides constructs comprising an antibody moiety that specifically binds to PSMA (e.g., PSMA expressed on the surface of a cell). Also provided are methods of making and using these constructs.

Provided in the present invention are an improved hinge area and the use of same in constructing CAR skeleton. The amino acid sequence of the improved hinge area is as shown in SEQ ID NO.1 or SEQ ID NO.2 or SEQ ID NO.3, and the hinge area can prolong the survival of CAR-T cells in vivo and/or improve the capability of CAR-T cells to infiltrate tumors.

Fusion proteins comprising IL2 and IL2R (e.g., CIRB), IL2, IL2R and IL21R (e.g., CIRB21), and/or comprising IL2, IL2R, and CD28 (e.g., CIRB28); natural killer (NK) cells that express the fusion proteins and methods of use thereof, e.g., to treat subjects with cancer; and regulatory T cells (T-regs) that express a fusion protein comprising IL2, IL2R, and CD28 and methods of use thereof, e.g., to treat subjects with autoimmune disease or GVHD.

The present disclosure relates to compositions and methods for treating cancer. For example, a modified cell may include a polynucleotide comprising an NFAT promoter, a nucleotide sequence encoding therapeutic agent, and a nucleotide sequence encoding a VHL-interaction domain of HIF1, wherein the therapeutic agent comprises, for example, IL-12, IL-6, and/or IFN.

The invention provides in part methods of treating cancers of a specific organ or tissue by administering a composition that is antigenically specific for one or more microbes that are pathogenic in the specific organ or tissue in which the cancer is situated.

Compositions and methods are disclosed herein for producing one or more immunoglobulins in an isolated B lymphocyte cell line. An isolated cell line includes an isolated B lymphocyte cell line capable of expressing at least one exogenously incorporated membrane immunoglobulin reactive to a first antigen and at least one endogenous secreted immunoglobulin reactive to a second antigen.

Described herein is a reliable method for preparing a potent vaccine useful for immunotherapy comprising the step of cryopreserving a population of cells undergoing immunogenic cell death, and using such cells to activate dendritic cells for use in immunotherapy. In a specific embodiment, the method comprises cryopreserving cancer cells undergoing cell death, which can be used to prepare a pharmaceutical composition for immunotherapy against cancer.

Methods are disclosed for producing defective ribosomal products (DRiPs) in blebs (DRibbles) by contacting cells with a proteasome inhibitor, and in some examples also an autophagy inducer, thereby producing treated cells. DRibbles can be used to load antigen presenting cells (APCs), thereby allowing the APCs to present the DRiPs and antigenic fragments thereof. Immunogenic compositions that include treated cells, isolated DRibbles, or DRibble-loaded APCs are also disclosed. Methods are also provided for using treated cells, isolated DRibbles, or DRibble-loaded APCs to stimulate an immune response, for example in a subject. For example, DRibbles obtained from a tumor cell can be used to stimulate an immune response against the same type of tumor cells in the subject. In another example, DRibbles obtained from a pathogen-infected cell or cell engineered to express one or more antigens of a pathogen can be used to stimulate an immune response against the pathogen in the subject.

Disclosed herein are compositions and methods for treating or inhibiting prostate cancer. The compositions include a MHC molecule including covalently linked first and second domains, wherein the first domain is an MHC class II 1 domain and the second domain is an MHC class II 1 domain, wherein the amino terminus of the 1 domain is covalently linked to the carboxy terminus of the 1 domain, and a prostate specific antigen peptide covalently linked to the first domain. The methods include administering a disclosed MHC molecule to a subject with prostate cancer.
