Scientists Use Antibody To Shrink Tumors of Different Cancers

Kevin Anderson - Wednesday, March 28, 2012

Researchers at the Stanford University School of Medicine have found that an antibody blocks a protein known as CD 47. This protein sends off signals to the body's immune system telling it to pass it by when the macrophages and other cells that eat invaders come by. CD 47 is found in cancer cells, which is why the body's immune system does not fight cancer cells itself. In mice, this treatment significantly reduced the tumors ability to spread and made the tumors shrink and in some cases disappear within weeks of starting treatment.
