Diazinon acute exposure induces neutrophil extracellular traps in Nile tilapia (Oreochromis niloticus)

Abstract

Diazinon is an organophosphate insecticide commonly used worldwide to chemically control different organisms considered as pests. In the past years, diazinon has been described to have immunotoxic effects in several species. Nile tilapia is a teleost fish with an ecological and economic importance, which is also one of the fishes with the highest consumption around the world. The aim of this study was to evaluate the production of neutrophil extracellular traps (NETs) from fish Nile tilapia (Oreochromis niloticus) exposed to diazinon (0.97, 1.95, and 3.91 mg/L) for 6 and 24 h. The results obtained indicate that the exposure to diazinon per se increases NETs production. Therefore, these results could be involved in the understanding of the inflammatory process induced by exposure to pesticides.
