The dance of death

In the time it takes you to read this one sentence, ten million cells within your body would have died through a type of cell death known as apoptosis. Cell death is vital to remove old and damaged cells, and is associated with many disease settings. Previously, we discovered that dying immune cells can undergo an explosive process we call, the dance of death. My research has since focused on understanding the impact of cell fragmentation and phagocytosis during inflammatory settings.
