A protein which ‘turbo-charges’ the immune
system so that it can fight off any cancer or virus has been discovered
by scientists. In a breakthrough
described as a ‘game-changer’ for cancer treatment, researchers at
Imperial College found a previously unknown molecule which boosts the
body’s ability to fight off chronic illnesses. Scientists at Imperial College London, who led the study, are now
developing a gene therapy based on the protein and hope to begin human
trials in three years.
“This is
exciting because we have found a completely different way to use the
immune system to fight cancer,” said Professor Philip Ashton-Rickardt,
from the Section of Immunobiology in the Department of Medicine at
Imperial, who led the study.
“This is a completely unknown protein. Nobody had ever seen it before or was even aware that it existed. It looks and acts like no other protein.”The protein, named lymphocyte expansion molecule, or LEM, promotes the spread of cancer killing ‘T cells’ by generating large amounts of energy.
Normally when the immune system detects cancer it goes into overdrive trying to fight the disease, flooding the body with T cells. But it quickly runs out of steam. However the new protein causes a massive energy boost which makes T cells in such great numbers that the cancer cannot fight them off. It also causes a boost of immune memory cells which are able to recognize tumors and viruses they have encountered previously so there is less chance that they will return.
The team is hoping to produce a gene therapy whereby T cells of cancer patients could be enhanced with the protein and then injected back into the body. It could end the need for harsh chemo-therapies as the body itself would be fighting the disease, rather than toxic drugs.
