Dead cells modulate how immune cells function - life short science news

Immune cells prioritize removal of dead cells over fighting infections and healing wounds, a new study found.

While clearance of dead cells is important, during times of injury immune cells are needed at the wound to prevent infections and aid healing processess. Also, these cells can worsen many human conditions if they are at the wrong site or overactive.

Researchers found that the protein Simu is needed to keep macorphages at wound sites in fruit flies, so that targeting this protein in humans might provide new possibilities for improved wound healing and less infections in the future.
