The protein PD-1 is a checkpoint to slow down T-cells. #128442095
Description

PD-1 red extends from the surface of a T-cell and interacts with the ligand protein PD-L1 yellow from a antigen presenting cell. Although the T-cell has been activated through the interaction of a T-cell receptor blue and a MHC protein violett, PD-1 regulates these activation down. It is a checkpoint to slow down T-cells.
