A special form of lytic cell death is the formation of neutrophil extracellular traps (NETs), large structures of chromatin and antimicrobial proteins, which are released by dying neutrophils to capture extracellular pathogens and limit the spread of infections.
WebDec 1, 2024 · In a final act of protection, dying neutrophils mix their nuclear DNA with toxic components from their cytosolic granules and release it explosively to form a neutrophil extracellular trap (NET) in the surrounding environment.
