Cancer Cells May Be Able to Urge Their Own Death

WEDNESDAY, Dec. 22 (HealthDay News) — New research suggests that many cancer cells are equipped with a kind of suicide pill: a protein on their surfaces that gives them the ability to send an “eat me” signal to immune cells.

The challenge now, the researchers say, is to figure out how to coax cancer cells into emitting the signal rather than a dangerous “don’t eat me” signal.
Study suggests that harnessing this trait could improve treatmentsA study published online Dec. 22 in Science Translational Medicine reports that the cells send out the enticing “eat me” signal by displaying the protein calreticulin. But another molecule, called CD47, allows most cancer cells to avoid destruction by sending the opposite signal: “Don’t eat me.”
