Phagocytic signalling
Phagocytic signalling is a complex array of signals involved in regulating the phagocytosis ("eating") of targets by phagocytes.

Phagocytic signals can be both extracellular and membrane bound and are currently categorised into 7 groups: opsonins, negative opsonins, phagocyte suppressors, find-me signals, phagocytic receptors, eat-me signals, and don't-eat-me signals. The presence or lack of signals depends on the context of both the phagocyte and target, for example cells undergoing apoptosis will have phosphatidylserine, an eat-me signal, present on their surface. Whilst many signals that are associated to phagocytosis have been identified, it is still unclear how signals interact cumulatively.
