ABSTRACT:
T cell activation in response to antigen is increased by the administration of binding agents that block CTLA-4 signaling. When CTLA-4 signaling is thus blocked, the T cell response to antigen is released from inhibition. Such an enhanced response is useful for the treatment of tumors, chronic viral infections, and as an adjuvant during immunization.
