HLA-A
HLA-A is the molecule that holds up short pieces of a cell's proteins for T cells to inspect. Engineered T-cell receptor therapies such as tebentafusp and afami-cel only work in people with the HLA-A*02 variant, because the receptor recognises the tumour peptide sitting in that particular groove. This dossier gathers the 4 products (2 approved), 7 trials, 0 pathways and 0 resistance routes in the corpus that involve it, with external identifiers so it can be joined to UniProt, ChEMBL, Open Targets and the rest of biology.
Biology
The antigen-presentation pathway record describes the escape routes: tumours that lose beta-2-microglobulin or HLA stop showing peptides and become invisible to CD8 T cells and to these therapies, and the HLA genotype shapes which mutations are visible at all.
- Eligibility marker (HLA-A*02) for TCR-T and soluble TCR therapies in uveal melanoma, synovial sarcoma and myxoid/round cell liposarcoma
- All nucleated cells (antigen presentation)
