CD80

CD80

a type I transmembrane protein on activated B cells, activated monocytes, activated follicular dendritic cells, and some activated T cells; provides a costimulatory signal to T cells during antigen presentation; expressed in B lymphoblastoid cells.

Imfinzi (durvalumab) is a human monoclonal antibody that binds to PD-L1 and blocks the interaction of PD-L1 with PD-1 and CD80, countering the tumor's immune-evading tactics and releasing the inhibition of immune responses.
