By James A. Foley Mar 29, 2013
Cancer researchers made a groundbreaking discovery by developing a sort-of "Ultimate antibody" -- a single treatment that has been shown to kill every type of cancer it was tested on.
The latest developments are based on research that began a decade ago at Stanford School of Medicine, where researchers discovered a link between cancer cells and high levels of a protein called CD47 while studying leukemia. Irving Weissman, the biologist behind the breakthrough, continued to study CD47 and found at a CD47-blocking antibody that could cure some cases of leukemia by stimulating the immune system to recognize cancer cells as invaders.
Now, Weissman has established a link between CD47 and most of primary caners that affect humans, finding that cancer cells always had higher levels of CD47 than healthy cells. The inordinate amounts of CD47 produced by the cancer cells effectively trick the immune system into not destroying the cancer cells.
"What we've shown is that CD47 isn't just important on leukemias and lymphomas," says Weissman, according to Science magazine. "It's on every single human primary tumor that we tested."
Weissman and his team used that observation to develop an antibody that blocks cancer cells' CD47, causing the body's immune system to attack the cancerous cells.
