摘要:
The embodiments provide for the modulation of both the differentiation and activity of human TH17 cells. More specifically, human TH17 cell differentiation can modulated by TGF-? and IL-21, and their agonists and antagonists. Function of TH17 cells can be modulated by, for example, BLT1 or podoplanin, and their agonists and antagonists. Additionally, the embodiments provide for the identification of TH17 cells. More specifically, human TH17 cells specifically upregulate BLT1 and podoplanin.
摘要:
The present invention provides compositions and methods useful for promoting or reducing T-cell trafficking to a target tissue. Also provided are compositions and methods useful for promoting or inhibiting antigen-presenting cell (APC) activation. The invention is related to discovery of functional characteristics of TIM-3, a molecule that is preferentially expressed on the surface of Thl cells. The methods are useful for treating disorders including cancer, infectious disease, allergy, asthma, and autoimmune disease.
摘要:
Described herein are methods for suppressing an immune response in a subject, e.g., a subject with an autoimmune disease, by administering to the subject a therapeutically effective amount of recombinant CD5L, CD5L homodimers and/or CD5L:p40 heterodimers, or nucleic acids encoding any of these. Also described are methods for enhancing an immune response in a subject, e.g., a subject with cancer, infection, or an immune deficiency, by administering to the subject a therapeutically effective amount of an antibody or antigen-binding fragment thereof that binds specifically to CD5L, D5L homodimers and/or CD5L:p40 heterodimers, and inhibits their binding to the IL-23 receptor, or inhibits formation of the CD5L homodimer and/or CD5L:p40 heterodimer, or inhibitory nucleic acids that target CD5L and/or p40.
摘要:
The invention provides novel methods of treating neurological disorders, including neurodegenerative disorders such as MS. The invention also provides novel methods of treating cancers, including glial tumors such as glioblastoma multiforme. The invention further provides vaccines and related uses.
摘要:
Described herein are compositions and methods for the modulation of T-cell tolerance, which can be upregulated or down regulated by concurrent enhancement or inhibition of CEACAM1/TIM3 interactions. As described herein, the discovery that CEACAM1 is a direct ligand of TIM3 and vice versa has been shown in cis and in trans. In addition, as demonstrated herein, CEACAM1 and TIM3 are co-regulated during the course of T-cell activation.
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.
