Phagocyte recognition of cells undergoing apoptosis.

Author information

  • 1Dept of Medicine, Royal Postgraduate Medical School, Hammersmith Hospital, London, UK.


A key feature of apoptosis is that cells undergoing this programmed form of death are recognized by phagocytes and ingested while still intact, protecting tissues from the potentially harmful consequences of exposure to the contents of the dying cells. This article reviews recent data which indicate that phagocyte recognition of apoptotic cells as 'senescent-self' involves at least three classes of receptors on the phagocyte surface, while apoptotic cells may display their 'edible' status in a number of different ways.
