Provided herein are chimeric antigen receptors (CARs), cells comprising the CARs, monoclonal and bispecific antibodies or antigen-binding fragments thereof, and kits comprising the same. The CARs and bispecific antibodies are designed to target at least one tumor antigen and at least one tumor in methods of treating cancer in subjects in need thereof.

The present invention relates to a complex of a protein comprising zinc oxide-binding peptides and zinc oxide nanoparticles, to the use thereof as a drug delivery carrier for manufacturing medicines, and to a vaccine composition and a contrast agent comprising the composite. The protein comprising zinc oxide-binding peptides significantly improves the in vivo availability of zinc oxide-binding peptides, and therefore the complex of the present invention can be used not only as a drug delivery carrier for in vivo drug delivery or intracellular drug delivery, but also for in vivo imaging or cell imaging. The complex can be used for producing separating agents for effectively separating biological materials, therapeutic agents for hyperthermia, etc., contrast agents for MRI, and beads applicable to biosensors.

The present invention relates to nanoparticles complexed with biomacromolecule agents configured for treating, preventing or ameliorating various types of disorders, and methods of synthesizing the same. In particular, the present invention is directed to compositions comprising nanoparticles (e.g., synthetic high density lipoprotein (sHDL)) carrying biomacromolecule agents (e.g., nucleic acid, peptides, glycolipids, etc.), methods for synthesizing such nanoparticles, as well as systems and methods utilizing such nanoparticles (e.g., in diagnostic and/or therapeutic settings).

Disclosed are means, methods and compositions of matter useful for amplification of adaptive immune responses towards neoplastic tissue. In one embodiment, immunization of a patient is performed by a means comprising of administering either an exogenous vaccine or stimulation of immunogenicity of the tumor so as to cause release of antigens/increased exposure of antigens, thus resulting in an “endogenous” vaccine. Subsequent to vaccination a patient is treated by an immunopheresis procedure, in order to allow for removal of “blocking factors” produced by the tumor or produced by cells programmed by tumors to produce said blocking factors. In one embodiment further immunization is performed subsequent to removal of said blocking factors in order to allow for enhancement of adaptive immune responses

Some embodiments of the present disclosure are directed to methods that include delivering to a subject a nucleic acid encoding an antigen, wherein the nucleic acid is delivered via a tumor-selective vehicle or via intratumoral injection, and delivering to the subject an immune cell expressing a receptor that binds to the antigen.

The present invention relates to a nucleic acid sequence, comprising or coding for a coding region, encoding at least one peptide or protein comprising a tumour antigen or a fragment, variant or derivative thereof, at least one histone stem-loop and a poly(A) sequence or a polyadenylation signal. Furthermore the present invention provides the use of the nucleic acid for increasing the expression of said encoded peptide or protein. It also discloses its use for the preparation of a pharmaceutical composition, especially a vaccine, e.g. for use in the treatment of cancer or tumour diseases. The present invention further describes a method for increasing the expression of a peptide or protein comprising a tumour antigen or a fragment, variant or derivative thereof, using the nucleic acid comprising or coding for a histone stem-loop and a poly(A) sequence or a polyadenylation signal.

Hematopoeitic stem/progenitor cells (HSPC) and/or non-T effector cells are modified to express an extracellular component including a tag cassette. The tag cassette can be used to activate, promote proliferation of, detect, enrich, isolate, track, deplete and/or eliminate modified cells. The cells can also be modified to express a binding domain.

The present invention relates to a recombinant virus of the family Paramyxoviridae comprising an expressible polynucleotide encoding at least one of (i) a tumor antigen, (ii) a fragment of a tumor antigen, and (iii) a variant of (i) or (ii). The present invention further relates to a polynucleotide encoding said recombinant virus of the family Paramyxoviridae and to a host cell comprising said recombinant virus of the family Paramyxoviridae and/or said polynucleotide encoding said recombinant virus of the family Paramyxoviridae. Moreover, the present invention relates to a method for activating immune cells with antitumor activity in a sample comprising cancer cells and to further means, methods, and uses related to the present invention.

The present invention provides a cell which comprises a first chimeric antigen receptor (CAR) and a second CAR, wherein the first and second CARs bind different epitopes on the same ligand. The cell may be used in a method for treating a disease, such as cancer.

The present invention provides immunoresponsive cells, including T cells, cytotoxic T cells, regulatory T cells, and Natural Killer (NK) cells, expressing an antigen recognizing receptor and an inhibitory chimeric antigen receptor (iCAR). Methods of using the immunoresponsive cell include those for the treatment of neoplasia and other pathologies where an increase in an antigen-specific immune response is desired.
