Scientists believe that they have found part of the human immune system that can be used to treat all types of cancer.
It is believed that a team of researchers at Cardiff University found a method for destroying lung, breast, prostate, and other types of cancer in lab tests.
Nature Immunology published the findings which still haven’t been tested in humans. However, researchers believe this is exciting news for the treatment of cancer, even though the work is still at an early stage. They say the findings have great potential.
What’s the Discovery?
function of the immune system is to defend us from infections. However, it also
attacks cancer cells. Researchers were trying to find new unconventional ways
the immune system works to fight against tumors naturally.
They discovered a T-cell inside our blood – an immune cell that detects a threat in our body that needs to be attacked and removed.
the T-cell could attack different types of cancer.
Professor Andrew Sewell sees a chance here to treat every patient. Here’s what he said for 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 T-Cell Works
the receptors located at their surface, T-cells can see at a chemical level.
Researchers at the Cardiff University found a T-cell with a receptor that can
detect and destroy different cancerous cells in the lab, such as skin, lung,
breast, colon, bone, blood, ovarian, prostate, cervical, and kidney cancer
important, the T-cell didn’t touch the healthy cells.
way this cell and its receptor work is still unclear. The receptor of the
T-cell interacts with MR1 – a molecule found on the surface of every human
this molecule flags the improper metabolism inside cancer cells to the immune
Dolton, one of the researchers, told the BBC:
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.
Why Is This Important?
therapies involving T-cells already exist. One of the most incredible advances
in cancer treatment has been the development of cancer immunotherapy.
CAR-T is the most famous example. It’s a living drug produced by genetically engineering T-cells of one patient to detect and kill cancer.
can have incredible results, improving the condition of cancer patients
significantly. A terminally ill patient can go into complete remission.
method is extremely specific and works in certain types of cancer where a clear
target is present to train T-cells to detect. Also, the approach has barely any
success in solid cancers – cancers that form tumors rather than leukemia.
to the team of researchers at Cardiff University, the T-cell receptor they
discovered may lead to a universal treatment for cancer.
How Would This Work in
explain that after taking a blood sample from a patient, their T-cells would
have to be extracted and genetically modified in order to be reprogramed so
they can find the receptor that’s able to detect the cancer cells.
cells are upgraded in this way, they will be multiplied in a large number in
the lab and put back into the same patient. CAR-T therapies use the same process.
For now, the
research has been tested only on cells in the lab and in animals, so more
safety checks are needed before they can test it on humans.
What’s The Opinion of
According to Gennaro De Libero and Lucia Mori from the Swiss University of Basel, the research has a huge potential, although it’s too early to say it could work on all types of cancer.
We are very excited about the immunological functions of this new T-cell population and the potential use of their TCRs in tumour cell therapy.
Here’s the opinion of the professor of immunology at the University of Manchester, Daniel Davis:
At the moment, this is very basic research and not close to actual medicines for patients. There is no question that it’s a very exciting discovery, both for advancing our basic knowledge about the immune system and for the possibility of future new medicines.
