Abstract
Apoptosis results in the oxidation of membrane lipids on the dying cell. Newly identified oxidized lipids play a dual role: they contribute to the recognition and phagocytosis of dying cells, but may also spur antibody production and inflammation.
After a cell undergoes apoptosis, it is recognized and engulfed by neighboring tissue cells or professional phagocytes. This removal is highly efficient and normally anti-inflammatory.
