Molecular 'eat now' signal makes cells devour dying neighbors

surface, thus taking advantage of the cell's own transportation system. "We put C2 on the same bus as the membrane protein," Inoue says.

As a result, up to six dying cells stuck to each HeLa cell. The bad news was that though they were cozy, the HeLa cells weren't actually eating the dying cells.

Fortunately, Inoue says, the team already had an idea about what to try next: Other research had shown that activating a gene called Rac would cause a cell to engulf beads stuck to its surface. Sure enough, HeLa cells with both surface C2 and activated Rac swallowed dying cells readily, the team found.

"We've shown it's possible to endow ordinary cells with the power to do something unique: take on the role of a specialized macrophage," Inoue says.

Inoue cautions that the investigators don't believe the engulfed cells are being broken down. Getting the HeLa cells to finish the phagocytosis process will be one of the group's next steps.
