Scientists say a newly discovered type of killer immune cell has raised the prospect of a "universal" cancer therapy.
Researchers at Cardiff University suggest the new T-cell offers hope of a "one-size-fits-all" cancer therapy.
T-cell therapies for cancer - where immune cells are removed, modified and returned to the patient's blood to seek and destroy cancer cells - are the latest model in cancer treatments.
The most widely used is known as CAR-T and is personalised to each patient.
However, it only targets a limited number of cancers and has not been successful for solid tumours, which make up the majority of cancers.
But scientists have now discovered T-cells equipped with a new type of T-cell receptor (TCR) which recognises and kills most human cancer types, while ignoring healthy cells.
We hope this new TCR may provide us with a different route to target and destroy a wide range of cancers in all individuals.
