The present invention relates to the field of tumor immunology. It provides a method for identifying mutation-related human CD8+ T cells, in particular, tumor-specific T cells of a human subject, comprising analyzing CD8+ T cells of the subject by analysing the expression of at least one marker selected from a first group consisting of CD82, CD194, CD244, CD28, CD62L and CD55, and preferably, a marker selected from a second group comprising CD11a or CD18 or CD43. A preferred marker for mutation-related CD8+ T cells is CD82, which may be analysed in combination, e.g., with CD11a. Without the need to identify any epitope to which T cells reacts, this method can advantageously be used to isolate the entire individual pool of mutation-related T cells, and, optionally, to identify the sequence of a mutation-related TCR, which allows for generation of transgenic T cells expressing the TCR. Compositions substantially comprising tumor-specific CD82.sup.hiCD8+ T cells and/or CD194.sup.hi, CD244.sup.−, CD28.sup.+, CD62L.sup.+ and/or CD55.sup.+ CD82.sup.hi CD8+ T cells can be used for treatment of a cancer patient, e.g., by adoptive T cell transfer. The method of the invention can also be used for diagnostic purposes to identify human mutation-related T cells or diagnosing a tumor disease or for testing responses of a cancer patient to an immune stimulatory therapy, preferably, a therapy with a checkpoint inhibitor.

The present disclosure relates generally to methods and compositions for cancer immunotherapy, and more specifically, liquid markers for predicting effectiveness of cancer therapies. The disclosure features compositions and methods that are useful for predicting the efficacy of cancer treatment (e.g., a checkpoint inhibitor immunotherapy) and, in some embodiments, administering the cancer treatment such as immunotherapy.

Antibody molecules that bind to CD73 are disclosed. The anti-CD73 antibody molecules can be used to treat, prevent and/or diagnose cancer.

The present invention is based, in part, on the discovery of monoclonal and polyclonal antibodies that specifically bind to phosphorylated PD-1, as well as immunoglobulins, polypeptides, nucleic acids thereof, and methods of using such antibodies for diagnostic, prognostic, and therapeutic purposes.

The invention provides a therapy for lysosomal storage diseases and glycogenosis by treatment with compounds that promote exocytosis, preferably lysosomal exocytosis. The treatment of cells from patients affected by different lysosomal storage disorders with exocytosis activating compounds leads to a decrease in the accumulation of toxic substrate in the lysosomes, thus allowing the treatment, prevention and relief of the symptoms of many lysosomal storage disorders.

Methods are disclosed for treating a subject with a tumor. These methods include administering to the subject a therapeutically effective amount of CD8.sup.+CD39.sup.+CD103.sup.+ T cells. Methods also are disclosed for isolating a nucleic acid encoding a T cell receptor (TCR) that specifically binds a tumor cell antigen. These methods include isolating CD8.sup.+CD39.sup.+CD103.sup.+ T cells from a sample from a subject with a tumor expressing the tumor cell antigen, and cloning a nucleic acid molecule encoding a TCR from the CD8.sup.+CD39.sup.+CD103.sup.+ T cells. In addition, methods are disclosed for expanding CD8.sup.+CD39.sup.+CD103.sup.+ T cells. In additional embodiments, methods are disclosed for determining if a subject with a tumor will respond to a checkpoint inhibitor. The methods include detecting the presence of CD8.sup.+CD39.sup.+CD103.sup.+ T cells in a biological sample from a subject.

The present disclosure provides methods for processing extracellular vesicles in which the extracellular vesicles are not purified, prior to contacting with a fluorescent staining dye or an antibody. By utilizing a centrifugal filter, excess staining dye or antibody can be readily removed prior to analysis of one or more characteristics of the extracellular vesicles. The methods provide rapid and simple processing and analysis, while maintaining a high concentration of extracellular vesicles.

The present invention relates to a method for diagnosis of delayed bone fracture healing, comprising determining the frequency of a subpopulation of CD8+ cells selected from a first group comprised of CD8+CD57+, CD8+CD28− and CD8+CD28−/CD57+, in a sample obtained from a subject. The present invention further relates to a system and a kit of parts for prediction and resulting options for preventing of delayed bone fracture healing.

Provided herein are combination therapies for the treatment of cancer. In particular, the disclosed methods are directed to treatment of cancer in a patient comprising administering an antibody that blocks the interaction between PD-1 and PD-L1 and an FGFR inhibitor, wherein the antibody that blocks the interaction between PD-1 and PD-L1 and the FGFR inhibitor are administered if one or more FGFR variants are present in a biological sample from the patient.

Described herein are devices and methods for high throughput purification of particles. In some cases, methods and devices described herein can be used to remove erythrocytes and purify leukocytes and raise the quality of umbilical cord blood and other transplant grafts, thereby significantly improving patient outcomes.
