Rapidly empowering cells to eat dying neighbor cells

In the present study, we have developed a novel method termed DISplay with which biomolecules of interest were displayed at the cell surface within an hour. Armed with this method, we could rapidly make targeted cells stick to dying but not living cells. Additional Rac activation then turned these cells into an “eat you” mode, resulting in ingestion of dying neighbor cells. In the near future, we hope the DISplay method will become a seed cell therapy to clean up junk in our body such as pathological cancer cells and toxic substances like amyloid beta plaques.
