co-stimulation

Immunology The delivery of a 2nd signal from an antigen-presenting cell to a T cell, which rescues an activated T cell from anergy, allowing it to produce the lymphokines necessary for production of additional T cells

His work has led to the development of multiple therapies that promote immune tolerance, including CTLA4Ig (Abatacept), used in the treatment of rheumatoid arthritis; the first FDA-approved drug targeting T cell co-stimulation to treat autoimmune disease and organ transplant rejection (Belatacept); a novel anti-human-CD3 antibody being developed to treat type 1 diabetes; and the first CTLA-4 antagonist drugs approved for the treatment of metastatic cancer.
