Background: The B-lymphocyte activation antigen B7-1 (referred to as B7); also known as CD80; is a member of cell surface immunoglobulin superfamily and is expressed on the surface of antigen-presenting cells including activated B cells; macrophages and dendritic cells. As costimulatory ligands; B7-1 which exists predominantly as dimer and the related protein B7-2; interact with the costimulatory receptors CD28 and cytotoxic T lymphocyte-associated antigen 4 (CTLA-4) expressed on T cells; and thus constitute one of the dominant pathways that regulate T cell activation and tolerance; cytokine production; and the generation of CTL. The B7/CD28/CTLA4 pathway has the ability to both positively and negatively regulate immune responses. CD80 is thus regarded as promising therapeutic targets for autoimmune diseases and various carcinomas.Immune CheckpointImmune Checkpoint Detection: Antibodies Immune Checkpoint Detection: ELISA Antibodies Immune Checkpoint Detection: IHC Antibodies Immune Checkpoint Detection: FCM Antibodies Immune Checkpoint Detection: WB AntibodiesImmune Checkpoint ProteinsImmune Checkpoint Targets Co-inhibitory Immune Checkpoint Targets Immunotherapy Cancer Immunotherapy Targeted Therapy
