Cancer cells produce a protein named CD47. By blocking CD47 with an antibody, they discovered it cured some cases of lymphoma and leukemia in mice by stimulating the immune system to see the cancer cells as invaders.
Further, the antibody can either cure the tumor or slow its growth and prevent metastasis. What is exciting is the ability for this antibody to also attack every kind of tumor tested by researchers!
Human cancer cells transplanted into mice such as breast, ovary, colon, bladder, brain, liver and prostate all seemed to respond to the antibody (single drug).
Further studies are necessary and could begin as early as 2014 in humans.
