Scientists Discovers One Size Fit All Cancer Treatment, Using A Part Of Our Immune System

Scientists have discovered that part of our immune system could be harnessed to treat all cancers, raising the prospect of a ‘one-size-fits-all’ cancer treatment

The findings, published in Nature Immunology by Cardiff University team discovered a method of killing prostate, breast, lung and other cancers in lab tests but have not been tested in patients, which the researchers say they have “enormous potential”.

Experts said that although the work was still at an early stage, it was very exciting of how Our immune system is our body’s natural defence against infection, but it also attacks cancerous cells.

The scientists were looking for “unconventional” and previously undiscovered ways the immune system naturally attacks tumours.

What they found was a T-cell inside people’s blood. This is an immune cell that can scan the body to assess whether there is a threat that needs to be eliminated.

The difference is this one could attack a wide range of cancers.

“There’s a chance here to treat every patient,” researcher Prof Andrew Sewell told the BBC. “Previously nobody believed this could be possible.

“It raises the prospect of a ‘one-size-fits-all’ cancer treatment, a single type of T-cell that could be capable of destroying many different types of cancers across the population.”

How does it work?

Exactly how it does this is still being explored. T-cells have “receptors” on their surface that allow them to “see” at a chemical level.

The Cardiff team discovered a T-cell and its receptor that could find and kill a wide range of cancerous cells in the lab including lung, skin, blood, colon, breast, bone, prostate, ovarian, kidney and cervical cancer cells.

Crucially, it left normal tissues untouched.

This particular T-cell receptor interacts with a molecule called MR1, which is on the surface of every cell in the human body.

It is thought MR1 is flagging the distorted metabolism going on inside a cancerous cell to the immune system.

“We are the first to describe a T-cell that finds MR1 in cancer cells – that hasn’t been done before, this is the first of its kind,” research fellow Garry Dolton told the BBC.
