Disclosed herein is a personalized tumor vaccine comprising attenuated cancer cells and a method of using said personalized tumor vaccine to treat cancer.

This document provides novel compositions and methods utilizing immunomodulating agents that can stimulate or indirectly augment the immune system, or can have an immunosuppressive effect. TNFR25 agonists disclosed herein have an anti-inflammatory and healing effect. They can be used, e.g., to treat disease caused by asthma and chronic inflammation, such as inflammatory bowel diseases including ulcerative colitis and Crohn's Disease. TNFR25 antagonists disclosed herein can inhibit CD8 T cell-mediated cellular immune responses and can, for example, mitigate organ or tissue rejection following a tissue transplantation. TNFR25 agonists disclosed herein represent biological response modifiers that alter the interaction between the body's cellular immune defenses and cancer cells to boost, direct, or restore the body's ability to fight the cancer when given with tumor vaccines. TNFR25 specific immunotoxins disclosed herein are also capable of increasing the effectiveness of a chemotherapeutic regimen by depleting a cancer patient of naturally occurring immunosuppressive cells.

The present invention includes a method of preparing apoptotic bodies from a tumour and immunogenic compositions thereof. The method of preparation comprises: obtaining human tumour cells from a subject, inducing apoptosis of the human tumour cells with a drug or a physical treatment, and collecting apoptotic bodies from the apoptotic human tumour cells by centrifugation. The method comprises two centrifugation steps, low-speed at 50 g for 5 minutes to pellet cells, followed by high-speed centrifugation of the obtained supernatant at 3,000 g for 8 minutes to pellet apoptotic bodies. The purity of the apoptotic bodies (also referred to as immunogenic Tumor Apoptotic Bodies (TABi)) was determined by FACS to be 82.22%.

A delivery system for delivering water-soluble components and water-insoluble components of whole-cell components using nano-sized or micro-sized particles, and a use of which in preparing vaccines for preventing and treating cancer. The whole-cell components delivery system consisting of a nano-sized or micron-sized particle and whole-cell components loaded on the particle, the whole-cell components are water-soluble components and water-insoluble components of a whole cell in a cell or tissue. The mutated proteins or peptides produced by cancer in cellular components are loaded on nanoparticles or micronparticles. These immunogenic substances generated by mutations in disease in whole-cell components can be used for cancer prevention and treatment and preparing vaccines for preventing and/or treating cancer.

A method for producing at least one microneedle containing a vaccine for transdermal delivery of the vaccine to a patient includes preparing microparticles or nanoparticles of encapsulated vaccine by preparing a solution comprising a vaccine antigen and a biocompatible polymer matrix; and spray drying the solution to form the microparticles or nanoparticles. The method includes the further steps of preparing a film composition including at least one pre-polymer solution; preparing a suspension comprising the microparticles or nanoparticles and the film composition; loading the suspension into a 3D printer; printing, via the 3D printer, at least one microneedle made from the suspension; and, converting the pre-polymer solution into a cross-linked biopolymer by exposing the at least one microneedle to UV light. Also disclosed are microneedles containing a vaccine for transdermal delivery.

Chimeric antigen receptors containing CD33 antigen binding domains are disclosed. Nucleic acids, recombinant expression vectors, host cells, antigen binding fragments, and pharmaceutical compositions, relating to the chimeric antigen receptors are also disclosed. Methods of treating or preventing cancer in a subject, and methods of making chimeric antigen receptor T cells are also disclosed.

A method for treating a tumor in a patient by administering to the patient an immunogenic composition including antigenic material inactivated by treatment with a metal-based coordination complex and electromagnetic radiation, wherein the immunogenic composition is effective to elicit an immune response to the antigenic material in the patient after administration and the metal-based coordination complex having a specified formula. An immunogenic composition and a method for preparing it are also disclosed.

Compounds, compositions, and methods for use in inhibiting the E3 enzyme Cbl-b in the ubiquitin proteasome pathway are disclosed. The compounds, compositions, and methods can be used to modulate the immune system, to treat diseases amenable to immune system modulation, and for treatment of cells in vivo, in vitro, or ex vivo. Also disclosed are pharmaceutical compositions comprising a Cbl-b inhibitor and a cancer vaccine, as well as methods for treating cancer using a Cbl-b inhibitor and a cancer vaccine; and pharmaceutical compositions comprising a Cbl-b inhibitor and an oncolytic virus, as well as methods for treating cancer using a Cbl-b inhibitor and an oncolytic virus.

Provided herein are endothelin receptor antagonistic lasso peptides and related compositions and methods for the management, prevention and/or treatment of an endothelin B receptor (ETBR)-mediated proliferative disease, such as cancer. Biosynthetic methods for producing the lasso peptides are also provided. In some embodiments, the method comprises administering to the subject a therapeutic effective amount of a lasso peptide, wherein the lasso peptide comprises an amino acid sequence selected from SEQ ID NOS:1-17 and 42-56. In particular embodiments, the lasso peptide is GI-D9 cyclized.

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.
