摘要： The present invention provides antibodies, or antigen-binding portions thereof, which specifically bind to IL-2 and reduce the affinity of IL-2 binding to IL-2Rα and IL-2Rβ. The invention further provides a method of obtaining such antibodies and nucleic acids encoding the same. The invention further relates to compositions and therapeutic methods for use of these antibodies for the treatment and/or prevention of autoimmune diseases, disorders or conditions and for immunosuppression, including, but not limited to, administering a complex comprising the antibody and IL-2.

摘要： The present disclosure relates generally to the manufacture of regulatory T cells (Tregs) for use in immunotherapy. In particular, the present disclosure relates to robust approaches for the expansion of alloantigen-reactive Tregs ex vivo. Alloantigen-reactive Tregs produced in this way are suitable for the induction and/or maintenance of immunologic tolerance in recipients of allogeneic transplants.

摘要： Provided herein are sphingolipid compounds that are useful for activating natural killer T cells. Also provided are methods for treating or preventing a disease or disorder that is treatable by activating the immune system by stimulating natural killer T cells. The compounds are therefore useful for treating or reducing the likelihood of occurrence of an immune diseases and disorders, such as autoimmune diseases or disorders. The compounds may also be used for treating or reducing the likelihood of occurrence of a microbial infection or for treating or reducing the likelihood of occurrence of a cancer in a subject by administering the sphingolipid compounds described herein.
