NET-associated assessment and potential intervention framework in NEC. NET-associated processes in NEC are conceptually divided into three stages: NET formation, NET persistence or impaired clearance, and downstream immunothrombotic injury. Representative markers include tissue extracellular DNA with MPO/NE colocalization, H3cit, MPO–DNA/NE–DNA complexes, cfDNA, platelet- and coagulation-related markers, inflammatory markers, and intestinal perfusion assessment. Potential intervention points include nNIF-related strategies, PAD4 or GSDMD inhibition, modulation of the IP6K1/neutrophil–platelet axis, DNase-mediated degradation, enhancement of macrophage-dependent clearance, and downstream endothelial or platelet modulation.
