Provided are methods and uses for treating a cancer or a tumor. In some aspects, the provided methods and uses involve contacting a sample, e.g., containing tumor cells, with a phthalocyanine dye conjugated to a targeting molecule that binds a protein on tumor cell, and illuminating the sample with a wavelength of light suitable for the activation of the phthalocyanine dye. In some aspects, the methods and uses also involve administering the illuminated sample to a subject, such as a subject having a cancer or a tumor. The methods and uses described herein provide for stimulation of the anti-cancer immune response in the subject and the reduction of growth and/or elimination of cancers, tumors and tumor cells in the subject. Also provided are compositions and combinations for use in the provided methods.

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 inventors provide a new therapeutic strategy to treat cancers expressing embryonic antigens. Accordingly, the present invention relates to a method of treating a subject suffering from a cancer comprising a step of administration simultaneously, separately or sequentially to said subject a therapeutically amount of i) a population of derived engineered fetal stem cells carrying cancer associated fetal neo-antigen and ii) a compound selected from a group which activates immune response, as a combined preparation.

The present invention provides a composition and method for treating diseases associated with demyelination of the nerves, such as ALS, RA, Tremors/Parkinson's Disease, and MS, Alzheimer's disease, ALS, Guillain-Barre syndrome, atherosclerosis, schizophrenia, Tremors/Parkinson's disease, senile dementia, Muscular Dystrophy, Attention Deficit Disorder, Attention Deficit Hyperactivity Disorder, Complex Regional Pain Syndrome, Diabetes, Neuropathic Pain, Spider Arthritis West Nile Virus,, Fibromyalgia, Shingles, Gout, Migraine Headaches, Post Polio Syndrome, Central Virus Deafness, Asthma, Chronic Pain Of Unknown Origin and Hepatitis C and for treating non-viral based cancers. By administering measured doses of an immunity-provoking agent and a bacterial antigen activator, patients suffering from ALS, RA, MS, Tremors/Parkinson's Disease, and prostate cancer and others realized immediate beneficial results with no side effects.

Disclosed herein is a method for treating a subject having, or at risk of having, a cancer, comprising administering to the subject a therapeutically effective amount of a tumor membrane vesicle (TMV) and a metformin. In some embodiments, the TMV comprises a B7-1 and/or IL-12 molecule anchored to a lipid membrane (e.g., by a GPI anchor). In some embodiments, the methods can further comprise administering an immune checkpoint inhibitor. The methods are useful for reducing tumor size and metastasis, and in improving anti-tumor immune responses.

The disclosure provides screening methods to identify small molecule compounds that can promote single circulating tumor cells (CTCs) proliferation, or alternatively inhibit proliferation by CTCs, and uses thereof, including as treatment options for cancer.

A tumor vaccine, a preparation method therefor, and use of the tumor vaccine thereof. A pharmaceutical combination with a first membrane component having a membrane derived from the inner membrane of bacteria, the pharmaceutical combination further includes components derived from other organisms than the bacteria. A method for enhancing an uptake of a target antigen by an immune cell, activating an immune cell, enhancing an innate immunity and/or a specific immune response and/or preventing and/or treating a tumor. A tumor vaccine for preventing postoperative recurrence of cancer.
