摘要:
The present invention relates to immunotherapeutic peptides and their use in immunotherapy, in particular the immunotherapy of cancer. The present invention discloses tumor-associated T-helper cell peptide epitopes, alone or in combination with other tumor-associated peptides that serve as active pharmaceutical ingredients of vaccine compositions which stimulate anti- tumor immune responses. In particular, the composition of the peptides of the present invention can be used in vaccine compositions for eliciting anti-tumor immune responses against gastric cancers (GC).

A compound of formula:[ I ] Pharmaceutical compositions containing the compound, and methods of inducing cytokine biosynthesis in an animal, treating a viral infection and/or treating a neoplastic disease in an animal by administering an effective amount of the compound to the animal are also disclosed.
摘要:
Disclosed are compositions, kits, and methods for inducing an immune response against disease. The dosage of antigen contained or utilized in the presently disclosed compositions, kits, and methods is substantially lower than dosages conventionally used in the field. The compositions, kits, and methods may be utilized to induce a cell-mediated response, such as a T-helper cell response, and/or a humoral response against a pathogen or a disease. In some embodiments, the compositions, kits, and methods may be utilized to induce preferentially a Th1 response versus other types of immune responses such as a Th2 response.
摘要:
One embodiment of the current disclosure relates to an immune-modulating composition comprising a hydrogel-forming polymer, an immune-modulating biomolecule operable to recruit or retain an immune cell, and an antigen-related biomolecule. Another embodiment of the current disclosure relates to a method of providing an antigen to an antigen presenting cell in an animal by administering to the animal at an administration site an immune-modulating composition as described above. Next, one forms a hydrogel in-situ from the hydrogel-forming polymer, then recruits at least one antigen presenting cell to the administration site using the immune-modulating biomolecule, and finally inducing phagocytosis of the at least one antigen- related biomolecule by the antigen presenting cell.
摘要:
The inventors have made the surprising discovery that SGK1, a serine/threonine kinase previously described as being involved in regulation of cellular sodium homeostasis, has a novel and unexpected function in the differentiation and function of a specific subset of CD4 T cells, the TH17 lineage. Described herein are methods and compositions for modulation of TH17 cell differentiation, proliferation, and/or function that rely upon modulating the activity or expression of SGK1. Such methods and compositions are useful in the treatment of disorders including autoimmune diseases, chronic inflammatory conditions, infectious diseases, and cancer.
摘要:
No effective vaccine exists for the devastating parasitic disease of Schistosomiasis. The present invention focuses on Sm-p80, a functionally important antigen of Schistosoma mansoni that plays a pivotal role in the schistosome immune evasion process. When used in a novel vaccine formulation, Sm-p80 demonstrates consistent immunogenicity, protective potential, and antifecundity effects. Two novel DNA constructs were made for immunization purposes. Sm- p80 coding sequence was cloned into VR 1020. Additionally, Sm-p80 coding sequence was cloned into pcDNA3.1 with flanking CpG motifs on each end of the Sm-p80 sequence. When used in different vaccine formulations, both of the constructs demonstrate the superior antifecundity and anti-worm effects of Sm-p80, which has great potential as an important vaccine candidate for the reduction of the morbidity associated with schistosome infection.
