PRTN3 and metabolic dysfunction-associated steatotic liver disease: The involvement of neutrophils in MASLD is widely supported by the observation of elevated levels of Myeloperoxidase (MPO) (91), neutrophil elastase (NE) (64), and proteinase 3 (PR3) (92), as well as neutrophil extracellular traps (NETs) (93) in MASLD patients, all of which have been implicated in promoting liver injury and the progression of MASH.
