Apoptotic PMN attract monocytes. (I) Apoptotic PMNs release neutrophil extracellular traps (NETs) with trapped granule proteins that may attract inflammatory monocytes. (II) Lysophosphatidylcholine (LPC) is released from apoptotic cells in a caspase-3–dependent manner. LPC then activates monocytic G2A receptor–inducing monocyte recruitment.
