The instant disclosure provides a combination treatment, composition and kit comprising (a) a long-acting IL-15 receptor agonist and (b) one or more antibodies (mAb) targeting a tumor antigen, related methods of preparation and use, for example, in the treatment of conditions responsive to therapy effective to provide, for example, sustained immune activation and/or anti-tumor activity.

Nucleic acid molecules and compositions comprising one or more nucleic acid sequences that encode a consensus Ebolavirus glycoproteinimmunogens are disclosed. The coding sequences optionally include operable linked coding sequence that encode a signal peptide. Immunomodulatory methods and methods of inducing an immune response against Ebolavirus are disclosed. Method of preventing Ebolavirus and methods of treating individuals infected with Ebolavirus are disclosed. Consensus Ebolavirus proteins are disclosed.

Methods for producing an antibody or an antigen-binding fragment thereof specifically binding to an antigen of interest, methods for inducing proliferation of PBMCs, B cell activation and differentiation, B cell maturation, and/or promoting class switch in an antibody-producing PBMC to produce IgG, compositions for the in vitro immunization and methods for identifying an antibody-enhancing factor for in vitro immunization.

Provided are genetically engineered induced pluripotent stem cells (iPSCs) and derivative cells thereof expressing a chimeric antigen receptor (CAR) and methods of using the same. Also provided are compositions, polypeptides, vectors, and methods of manufacturing.

The present disclosure is directed, in some embodiments, to methods and compositions of comprising a cell having a non-internalizing receptor, and a nanoparticle surface-modified with a ligand that binds to the non-internalizing receptor.

The present invention relates to compositions, methods, and kits for eliciting an immune response to at least one CMV antigen expressed by a cancer cell, in particular for treating and preventing cancer. CMV determination methods, compositions, and kits also are provided.

This invention provides methods of treating, reducing the incidence of, and inducing immune responses to a WT1-expressing cancer, by administering a combination of WT1 peptides including each of: YMFPNAPYL, RSDELVRHHNMHQRNMTKL, PGCNKRYFKLSHLQMHSRKHTG, SGQAYMFPNAPYLPSCLES, NLMNLGATL, WNLMNLGATLKGVAA, and WNYMNLGATLKGVAA, or cytotoxic T cells induced by the combination of WT1 peptides. The combination of WT1 peptides may be administered to the subject via a WT1 delivery agent, i.e., in peptide form, or in the form of nucleic acids encoding the WT1 peptides, or in the form of immune cells comprising nucleic acids encoding the WT1 peptides, and/or comprising or presenting the WT1 peptides. The WT1 delivery agents or CTLs can be administered to the subject in a single composition (as a heptavalent immunotherapy composition), or multiple compositions, resulting in delivery of all seven WT1 peptides and induction of an immune response against the WT1-expressing cancer.

Provided herein are immune cells expressing antigenic receptors, such as a chimeric antigen receptor and a T cell receptor. Further provided herein are methods of treating immune-related disorder by administering the antigen-specific immune cells.

Provided herein, inter alia, nucleic acids including coding sequences for human CD80, IL-15, IL-15Rα polypeptides, wherein the coding sequence for hCD80 is operably positioned upstream to the coding sequences for hIL-15 and hIL-15Rα. The disclosure also provides recombinant cells, cell cultures, pharmaceutical compositions, and whole-cell vaccines containing the recombinant cells disclosed herein. Also disclosed are methods useful for treating myeloma and leukemias, such as acute myelogenous leukemia (AML).

Disclosed herein are nucleic acid molecules comprising one or more nucleic acid sequences that encode a mutated consensus PRAME antigen. Vectors, compositions, and vaccines comprising one or more nucleic acid sequences that encode a mutated consensus PRAME antigen are disclosed. Methods of treating a subject with a PRAME-expressing tumor and methods of preventing a PRAME-expressing tumor are disclosed. Mutated consensus PRAME antigen is disclosed.
