Provided herein are vaccine composition comprising an antigen conjugated to a capsid, wherein the capsid comprises wild type or native sequence. Provided herein are also vaccine composition comprising an antigen conjugated to a capsid, wherein said capsid comprises at least one mutation, such as a non-natural mutation. Such compositions are useful in the treatment and prevention of pathogenic infections, inflammatory diseases, and neurodegenerative disease, and cancer, among others.

Provided are a bifunctional fusion protein and pharmaceutical use thereof. Specifically, provided are a bifunctional fusion protein comprising an SIRPγ peptide variant and an anti-human PD-L1 antibody, an SIRPγ peptide variant, and pharmaceutical use thereof. The bifunctional fusion protein can specifically bind PD-L1 and CD47 to block the binding of PD-L1 or CD47 to a receptor or ligand thereof. In addition, also provided are preparation and application of the bifunctional fusion protein, and treatment of cancers and immune-related diseases.

The invention relates to vaccines for breast cancer therapy. The invention also relates to methods of preventing and treating breast cancer using a breast cancer vaccine.

The present invention concerns a method for treating triple-negative breast cancer (TNBC) in an individual, and/or for inducing an immune response to HER2/neu in an individual with a triple-negative breast cancer expressing low levels of HER2/neu, the method comprising administering to the individual: (a) an effective amount of trastuzumab, or derivative thereof; and (b) an effective amount of nelipepimut-S, or variant thereof, optionally with an immunological adjuvant. Preferably, the method includes a preparatory or priming phase comprising a frequency and duration of trastuzumab or trastuzumab derivative administration sufficient to substantially increase the major histocompatibility complex (MHC)-mediated presentation of HER2 peptide fragments to the patient immune system. The invention also includes medicaments and kits for treating TNBC in an individual, and/or for inducing an immune response to HER2/neu in an individual with a TNBC expressing HER2/neu.

Certain universal neoepitopes and cancer specific neoepitopes and methods therefor are presented that may be used in immunotherapy and cancer diagnosis. Preferred therapeutic and diagnostic compositions include antibodies or fragments thereof that bind to neoepitopes on cancer cells.

Provided are compositions and methods for using the same. In some embodiments, the compositions include an EPELN encapsulating and/or having associated therewith an active agent and a plasma membrane derived from a tumor and/or cancer cell coating the EPELN. In some embodiments, the active agent is a therapeutic agent or an immune response modifier, and in some embodiments the plasma membrane has one or more tumor-associated and/or cancer-associated antigens. Also provided are methods for using the compositions for treating tumors and/or cancers, inducing anti-tumor and/or anti-cancer immune responses, activating antigen-presenting cells, targeting CD11c dendritic cells, and preventing or reducing metastasis.

Compositions and methods for immunization against human breast cancer are disclosed. A breast cancer vaccine comprises an immunogenic polypeptide comprising human α-lactalbumin.

A method for producing exosomes in a large-scale by using a cyclic tensile bioreactor to stimulate cells to release exosomes. In addition, the exosome having an anti-HLA-G protein specific for cancer is used as a delivery vehicle to deliver therapeutic agents for treating cancer.

Certain universal neoepitopes and cancer specific neoepitopes and methods therefore are presented that may be used in immunotherapy and cancer diagnosis. Preferred therapeutic and diagnostic compositions include antibodies or fragments thereof that bind to neoepitopes on cancer cells.

The present invention relates to peptides, proteins, nucleic acids and cells for use in immunotherapeutic methods. In particular, the present invention relates to the immunotherapy of cancer. The present invention furthermore relates to tumor-associated T-cell peptide epitopes, alone or in combination with other tumor-associated peptides that can for example serve as active pharmaceutical ingredients of vaccine compositions that stimulate anti-tumor immune responses, or to stimulate T cells ex vivo and transfer into patients. Peptides bound to molecules of the major histocompatibility complex (MHC), or peptides as such, can also be targets of antibodies, soluble T-cell receptors, and other binding molecules.
