摘要： Polymorphonuclear neutrophils (PMNs) are the most abundant leukocytes and are among the first line of immune system defense. PMNs can form neutrophil extracellular traps (NETs) in response to some pathogens. The release of NETs plays an important role in trapping and killing invading parasites. However, the effects of NETs on parasitic trematode infections remain unclear. In the present study, water buffalo NET formation, triggered by the newly excysted juveniles (NEJs) of Fasciola gigantica, was visualized by scanning electron microscopy. The major components of the structure of NETs were characterized by immunofluorescence. Viability of flukes incubated with water buffalo PMNs were examined under light microscopy. The results revealed that F. gigantic juveniles triggered PMN-mediated NETs. These NETs were confirmed to comprise the classic characteristics of NETs: DNA, histones, myeloperoxidase and neutrophil elastase. Although NETs were formed in response to viable larvae, the larvae were not killed in vitro. These results suggest that NET formation may serve as a mechanism to hamper the migration of large larvae to facilitate immune cells to kill them. This study demonstrates, for the first time, that parasitic trematode juveniles can trigger NET formation.
