Cancer cells can treat tumors

Cancer cells can treat tumors.
New investigating suggests that many cancer cells are equipped with a cordial of suicide pill: a protein on their surfaces that gives them the ability to send an "eat me" wink to immune cells. The challenge now, the researchers say, is to acknowledge out how to coax cancer cells into emitting the signal rather than a dangerous "don't eat me" signal england. A scrutiny published online Dec 22 2010 in Science Translational Medicine reports that the cells throw out the enticing "eat me" signal by displaying the protein calreticulin.

But another molecule, called CD47, allows most cancer cells to sidestep destruction by sending the antithesis signal: "Don't eat me". In earlier research, Stanford University School of Medicine scientists found that an antibody that blocks CD47 - turning off the whistle - could alleviate fight cancer, but mysteries remained hgh normal range. "Many normal cells in the body have CD47, and yet those cells are not attacked by the anti-CD47 antibody," Mark Chao, a Stanford graduate student and the study's lead author, said in a university dispatch release.
