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-1:
- Pidilizumab.
IHC
- There is no standard antibody.
- Currently, each drug company has its own clone. Whether the antibodies are interchangeable is a subject of study.
| Clone | IHC platform | Associated drug | Testing required |
|---|---|---|---|
| 28-8 | Dako | Nivolumab[3] | no testing for squamous carcinoma, pending further information for non-squamous |
| 22C3 | Dako | Pembrolizumab[4] | testing required |
| SP142 | Ventana | Atezolizumab[5] | testing required |
| SP263 | Ventana | Durvalumab | testing likely required |

- Programmed death-ligand 1 (PD-L1).
