Fig. 1: Three types of NET formation.
From: The emerging roles of neutrophil extracellular traps in wound healing

a The first type is classic suicidal NET formation, which is characterized by nuclear chromatin decondensation, NET release, membrane rupture, and cell death. b The second type is vital NET formation; after releasing NETs, neutrophils are intact and remain phagocytic. c The third type is mitochondrial DNA NET formation, which triggers NET formation from mitochondrial DNA but not nuclear DNA.
