CD80 Recombinant Protein

General information on CD80 Recombinant Protein:

Cluster of Differentiation 80, also known as B7-1, is a member of the cell surface immunoglobulin superfamily. It is expressed on the surface of antigen presenting cells, including activated B cells, macrophages and dendritic cells. CD80 plays a fundamental but different role in the activation of T cells. B7-1 / CD80 and B7-2 / CD86 and its CD28 and CTLA4 receptors constitute one of the main co-stimulatory pathways that regulate the response of T and B cells. CD80 is mainly expressed on the surface of antigen presenting cells, including activated B cells, macrophages and dendritic cells. Although CTLA-4 and CD28 can bind to the same ligand, CTLA-4 binds B7-1 and B7-2 with an affinity 20-100 times greater than CD28 and participates in the negative regulation of immune responses. Therefore, CD80 is considered a promising therapeutic target for autoimmune diseases and various types of cancer.
