The Cardiff University team discovered a method of killing prostate, breast, lung and other cancers in lab tests but it is at an early stage, not yet tested on patients.
The scientists were looking for "unconventional" and previously undiscovered ways the immune system naturally attacks tumours. A single type of T-cell could be capable of destroying many different types of cancers across the population, researchers say. The Cardiff team discovered a T-cell and its receptor that could find and kill a wide range of cancerous cells. This particular T-cell receptor interacts with a molecule called MR1, which is on the surface of every cell in the human body. The steps in the cancer treatment with this new method are: blood sample would be taken from a cancer patient, than their T-cells would be extracted and then genetically modified so they were reprogrammed to make the cancer-finding receptor.
A harmless virus will be used to deliver genes into T cells to make them recognise and target cancer cells. The modified T cells will be injected back into patient. This is called CAR–T therapy. The method is said to have great potential and becomes a hope for cancer treatment. A future entire new medecine is supposed to develop.
