Scientists film death of white blood cell for first time and discover alert system

Australian and US scientists capture on video each stage of death of a human white blood cell, revealing the dying cells apparently try to alert their neighbours

In a world first, Melbourne scientists have captured on video each stage of death of a human white blood cell, a phenomenon never seen before and which reveals the cells apparently try to alert their immune system allies that they are dying.

White blood cells are the critical, disease-fighting cells of the immune system which fight bacterial and fungal infections, as well as viruses.
