Immunopharmacology Comments |
CD80 (B7-1) is expressed on dendritic cells and activated B cells and monocytes. It is required to provide a costimulatory signal necessary for T cell activation and survival. CD80 works in concert with CD86 to prime T cells. CD80 binds CD28 and CTLA-4 on T cells. It is the interaction with CTLA-4 that is targeted by the approved immunosuppresive drugs abatacept and belatacept. |

General Comments |
This protein contains an immunoglobulin (Ig)-like domain that resembles the antibody variable domain, that has been coined the 'V-set domain'. The genes for all human V-set domain containing proteins are listed in HGNC gene group 590. |
