Scientists find treatment to kill every kind of cancer tumor
(Najamuddin Ghanghro, Karachi(original from Larkana))
Researchers might have found
the Holy Grail in the war against cancer, a miracle drug that has killed every
kind of cancer tumor it has come in contact with, the New York Post reported.
The drug works by blocking a protein called CD47 that is essentially a "do not
eat" signal to the body's immune system, according to Science Magazine.
This protein is produced in healthy blood cells, but researchers at Stanford
University found that cancer cells produced an inordinate amount of the protein
thus tricking the immune system into not destroying the harmful cells.
With this observation in mind, the researchers built an antibody that blocked
cancer's CD47 so that the body's immune system attacked the dangerous cells.
So far, researchers have used the antibody in mice with human breast, ovary,
colon, bladder, brain, liver and prostate tumors transplanted into them. In each
of the cases the antibody forced the mice's immune system to kill the cancer
cells.
