摘要:
Methods are disclosed for treating a subject with a tumor. These methods include administering to the subject a therapeutically effective amount of CD8+CD39+CD103+ 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+CD39+CD103+ 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+CD39+CD103+ T cells. In addition, methods are disclosed for expanding CD8+CD39+CD103+ 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+CD39+CD103+ T cells in a biological sample from a subject.
摘要:
A method of identifying an unknown spliced peptide derived from a known parent peptide contained in a biological sample, the method comprising: (1) a first step involving performing mass spectrometry on the sample to obtain mass spectrometry data regarding a peptide contained in the sample; (2) a second step involving searching a primary library, which is a database of known amino acid sequences, for an amino acid sequence that matches the mass spectrometry data, to identify a parent peptide contained in the sample; (3) a third step involving creating a secondary library including a candidate group of spliced peptides obtainable from the identified parent peptide; and (4) a fourth step involving searching the secondary library for an amino acid sequence that matches the mass spectrometry data, to identify a spliced peptide contained in the sample.
摘要:
A method is presented for screening cells that produce allogeneic autophagosome enriched compositions able to induce expression of a selective marker on a subpopulation of peripheral blood mononuclear cells, the method comprising contacting a cell with a proteasome inhibitor, contacting the cell with a lysosome inhibitor, harvesting the resulting autophagosomes, determining a molecular signature of the harvested autophagosomes, and selecting cells that divert one or more Toll-like receptor agonist and/or one or more molecular chaperones to the harvested autophagosomes. By screening for cells that divert one or more Toll-like receptor agonist and/or one or more molecular chaperones to the harvested autophagosomes, enriched populations of autophagosomes may be generated which may illicit a specific immune response against numerous cancer types. In this way, an allogeneic, off-the-shelf cancer vaccine may be produced and made available to be administered in order to stimulate a targeted immune response in patients bearing different tumor types.
摘要:
Methods and compositions of the invention relate to the enhancement of specific immunotherapies in cancer treatment. In particular, aspects of the invention relate to novel approaches to boost immune function using a complex carbohydrate pharmaceutical compound alone or in combination with other targeted immunotherapy to increase the efficacy of immunotherapy of cancer.
摘要:
OX40 is a potent immune stimulating target. Provided herein is a method of treating cancer, which includes administering to a subject in need of treatment an OX40 agonist and a common gamma chain (yc) cytokine or an active fragment, variant, analog, or derivative thereof In certain aspects the common gamma chain (yc) cytokine is interleukin-2 (IL-2) or an active fragment, variant, analog, or derivative thereof. Combined treatment with an agonist anti-OX40 mAb and IL-2 synergized to augment tumor immunotherapy against multiple tumor types. Dual therapy was also able to restore the function of anergic tumor-reactive CD8 + T cells.
摘要:
A system and method of displaying of multiple simultaneous views of a same region of a biological tissue sample. Logical instructions are executed by a processor to perform operations such as receiving a plurality of images of the biological tissue sample, converting the plurality of images to a common reference frame based on the individual metadata of each image, and arranging the plurality of images into a display pattern for simultaneous viewing of different aspects of the imaged biological tissue sample on a display screen. The plurality of images is produced by preprocessing images of the biological tissue sample. Each image shows a view mode of a same region of the biological tissue sample, and each image contains metadata that describe spatial orientation, such as the translation, rotation, and magnification, of the image to bring the plurality of images to a common view.
摘要:
The present invention relates to methods of inducing a T-cell response against a EGFRvIII in a subject. These method comprise administering to a subject a composition which expresses at least one immunogenic polypeptide, the amino acid sequence of which comprise a plurality of EGFRvIII polypeptide sequences, the sequence of which each comprise EEKKGNYV (SEQ ID NO: 3), and/or administering the polypeptide itself.
摘要:
The present invention features compositions and methods for enhancing an anti-tumor response by administering an OX40 agonist (e.g., an anti-OX40 antibody) and/or an anti-CTLA4 antibody (e.g., a CTLA4-blocking antibody) in combination with a cancer therapy.
