At Last! Scientists Create Cancer-Killing Cells That Can Be Injected Into Patients

If this actually works, then it calls for a worldwide celebration.

According to a dailymail reporter, scientists have created cells capable of killing cancer for the first time.

The dramatic breakthrough was made by researchers in Japan who created cancer-specific killer T cells. They say the development paves the way for the cells being directly injected into cancer patients for therapy.

The cells naturally occur in small numbers, but it is hoped injecting huge quantities back into a patient could turbo-charge the immune system.

Researchers at the RIKEN Research Centre for Allergy and Immunology revealed they have succeeded for the first time in creating cancer-specific, immune system cells called killer T lymphocytes.

To create these, the team first had to reprogramme T lymphocytes specialised in killing a certain type of cancer, into another type of cell called induced pluripotent stem cells (iPS cells).

These iPS cells then generated fully active, cancer-specific T lymphocytes.

These lymphocytes regenerated from iPS cells could potentially serve as cancer therapy in the future.

Previous research has shown that killer T lymphocytes produced in the lab using conventional methods are inefficient in killing cancer cells mainly because they have a very short life-span, which limits their use as treatment for cancer.

Doctor Kawamoto said: ‘We have succeeded in the expansion of antigen-specific T cells by making iPS cells and differentiating them back into functional T cells. 

‘The next step will be to test whether these T cells can selectively kill tumour cells but not other cells in the body. If they do, these cells might be directly injected into patients for therapy. This could be realised in the not-so-distant future.

The findings were published in the journal Cell Stem Cell.

Dr Dusko Ilic, Senior Lecturer in Stem Cell Science, King’s College London, said: ‘The study tackled a novel, quite interesting approach to cell based therapy, something that we do not usually hear about.

‘Although this approach requires further verification and a lot of work needs to be done before we can think about clinical trials, the initial data are promising.

‘This pioneering work definitely provides a strong foundation to build and expand our knowledge about new opportunities in cell based therapy and personalised medicine.’

What are your thoughts? Do you think we’ve finally gotten a cure for cancer as they claim?
