摘要:
The present invention is based, in part, on the discovery of monoclonal antibodies that specifically bind to the cytoplasmic domain of PD-L1 antibodies useful for diagnostic, prognostic, and therapeutic applications, as well as immunoglobulins, polypeptides, and nucleic acids thereof.
摘要:
The present invention provides novel compounds of Formula (I), and pharmaceutically acceptable salts, solvates, hydrates, tautomers, stereoisomers, isotopically labeled derivatives, and compositions thereof. Also provided are methods and kits involving the compounds or compositions for treating or preventing proliferative diseases (e.g., cancers (e.g., leukemia, melanoma, multiple myeloma), benign neoplasms, angiogenesis, inflammatory diseases, autoinflammatory diseases, and autoimmune diseases) in a subject. Treatment of a subject with a proliferative disease using a compound or composition of the invention may inhibit the aberrant activity of a kinase, such as a cyclin-dependent kinase (CDK) (e.g., cyclin-dependent kinase 7 (CDK7)), and therefore, induce cellular apoptosis and/or inhibit transcription in the subject.
摘要:
In various aspects the invention provides methods of predicting sensitivity of a cancer cell to a therapeutic agent by contacting a test cell population BH3 domain peptide; measuring the amount of BH3 domain peptide induced mitochondrial outer membrane permeabilization in the test cell population; and comparing the amount of BH3 domain peptide induced mitochondrial outer membrane permeabilization in the test cell population to a control cell population that has not been contacted with the therapeutic agent. An increase in mitochondrial membrane permeabilization in the test cell population compared to the control cell population indicates the cell is sensitive to the therapeutic agent.
摘要:
The present invention provides compositions and methods for modulating thermogenesis and related activities by modulating ΡΤΉ-related and EGF-related expression and activity. Also provided are methods for preventing or treating metabolic disorders in a subject through modulation of PTH-related and EGF-related expression and activity.
摘要:
Two or more peptides or polypeptides and an adjuvant for use in a method of inducing a tumor specific immune response, wherein the peptides or polypeptides have been identified by a method comprising: identifying a plurality of neoantigenic peptides for preparing a subject-specific immunogenic composition, each neoantigenic peptide comprising a tumor-specific neoepitope comprising a tumor-specific mutation, the method comprising: a. identifying a plurality of subject-specific tumor mutations in expressed genes of a subject having cancer by whole genome or whole exome nucleic acid sequencing of tumor and normal tissue samples from the subject, wherein the mutations are present in the genome of cancer cells of the subject but not in normal tissue from the subject; b. wherein when a mutation identified in step (a) is a point mutation: i. identifying a mutant peptide having the mutation identified in step (a), wherein said mutant peptide comprises a tumor-specific neoepitope which binds to a class I HLA protein with a greater affinity than a wild -type peptide; and has an IC50 less than 500 nm;
c. wherein when a mutation identified in step (a) is a splice-site, frameshift, read-through or gene-fusion mutation: i. identifying a mutant polypeptide encoded by the mutation identified in step (a), wherein said mutant polypeptide comprises a tumor-specific neoepitope which binds to a class I HLA protein.
摘要:
The present invention relates to methods for identifying, assessing, preventing, and treating cancer ( e.g ., head, neck, and/or lung cancers in humans). A variety of PD-LI isoforni biomarkers are pro v ided, wherein alterations in the copy number of one or more of the biomarkers and/or alterations in the amount, structure, and/or acti vity of one or more of the biomarkers is associated with cancer status and indicates amenability to treatment or prevention by modulating PD-1 and/or PD-L! levels.
摘要:
PD-1 antagonists are disclosed that can be used to reduce the expression or activity of PD-1 in a subject. An immune response specific to an infectious agent or to tumor cells can be enhanced using these PD-1 antagonists in conjunction with an antigen from the infectious agent or tumor. Thus, subjects with infections, such as persistent infections can be treated using PD-1 antagonists. In addition, subjects with tumors can be treated using the PD-1 antagonists. In several examples, subjects can be treated by transplanting a therapeutically effective amount of activated T cells that recognize an antigen of interest and by administering a therapeutically effective amount of a PD-1 antagonist. Methods are also disclosed for determining the efficacy of a PD-1 antagonist in a subject administered the PD-1 antagonist. In some embodiments, these methods include measuring proliferation of memory B cells in a sample from a subject administered the PD-1 antagonist.
