Programmed cell death 1, abbreviated PDCD1 and PD1,[1] is a protein (and gene) with an important role in immune system regulation and cancer. It is found on T lymphocytes.
It is also known as CD279.
PD1 binds with programmed death-ligand 1 (dealt with separately) and programmed death-ligand 2.[2]
Background
Cytotoxic T cell function is regulated by receptor pairs found on the tumour and lymphocyte:[2]
| Function | Tumour cell | T cell |
|---|---|---|
| Antigen presentation | MHC | TCR |
| Signal inhibition | PD-1 | PD-L1 (CD274), PD-L2 (CD273) |
Drugs
- Pembrolizumab.
- Nivolumab.
- Atezolizumab.
- Durvalumab.
- Avelumab.
Uncertain whether it binds PD-L1:
- Pidilizumab.
See also
- Programmed death-ligand 1 (PD-L1).
