The invention provides compositions, methods, and vaccines that may stimulate the immune system and that may be used for treating malignancies associated with overexpression of the HER3 protein. Such compositions include epitopes of the HER3 protein.

The present disclosure relates to vaccine formulations and their use in treating and preventing Chagas Disease.

The present invention refers to a novel combination of nucleotide and cellular vaccine composition and pharmaceutical composition and use thereof for treating and/or preventing diseases, including infectious diseases, cancer, autoimmune diseases, allergy, diabetes and blood disorders. The vaccine composition comprises a nucleotide sequence encoding an antigenic molecule and gene-modified antigen-presenting cells (APCs), preferably provided as an intermixture. The APCs are modified to express immune modulating molecules. Immunization with the vaccine composition of present invention into a subject, induces the host immune system to respond and generate efficient immunity against either pre-existing disease or protect the host against the disease.

Provided is an engineered immune cell. The engineered immune cell expresses (i) a chimeric receptor, and (ii) exogenous CCL3, CCL4 and/or CCL5, has improved tumor killing activity, and can be used to treat cancer, infection or autoimmune diseases.

An engineered immune cell comprising a first functional exogenous receptor capable of binding and depleting natural killer (NK) cells, and a second functional exogenous receptor, wherein the engineered immune cell has reduced MHC I on cell surface.

Provided are a polypeptide and nucleic acid for encoding the polypeptide, a nucleic-acid construct, an expression vector, and a host cell containing the nucleic acid, an antigen-presenting cell presenting the polypeptide on the surface of the cell, and immune effector cell thereof, a pharmaceutical composition containing the polypeptide, a vaccine containing the nucleic acid, the nucleic acid construct, the expression vector, the host cell, the antigen-presenting cell, and the immune effector cell, and an antibody recognizing the polypeptide. Also provided is a therapeutic method using the polypeptide, the nucleic acid, the pharmaceutical composition, the vaccine, and the antibody. Also provided are a diagnosis method and diagnosis apparatus for detecting the described polypeptide. Also provided is an application of the polypeptide in preparing a vaccine, a tumor diagnosis kit, or a pharmaceutical composition, and an application of the polypeptide or the nucleic acid as a test target in tumor diagnosis.

Disclosed herein are methods and compositions for treating cancer by eliciting an immune response by administering dendritic cells expressing heterologous proteins. In some embodiments, a dendritic cell comprises one or more heterologous nucleic acid molecules encoding for CD40L and CXCL13. In some embodiments, the dendritic cell further comprises a heterologous nucleic acid molecule encoding for CD93. In yet additional embodiments, the dendritic cells expressing heterologous proteins are activated.

The present invention relates to an antigen composition comprising at least one mesothelioma cancer cell associated antigen and a pharmaceutically acceptable carrier for use in the treatment of cancer, in particular mesothelioma, wherein dendritic cells are loaded with said antigen composition and wherein said loaded dendritic cells are administered in combination with one or more checkpoint inhibitors, to patients. The present invention also relates to an antigen composition comprising at least two mesothelioma cancer cell associated antigens and a pharmaceutically acceptable carrier. The present invention further relates to an antigen composition comprising at least two mesothelioma cancer cell associated antigens and a pharmaceutically acceptable carrier, for use as a pharmaceutical, in particular for use in the treatment of mesothelioma.

The present invention relates to chimeric receptors capable of facilitating cross-presentation (XP) of antigens, and methods of doing the same.

This disclosure provides nano-scale Artificial Antigen Presenting Cells (aAPC), which deliver stimulatory signals to lymphocytes, including T-helper lymphocytes, for use as a powerful tool for immunotherapy.
