The In Vitro Effects of Carprofen on Lipopolysaccharide-Induced Neutrophil Extracellular Trap Formation in Dairy Cows.

ABSTRACT: The objective of this study was to develop an in vitro model that mimics inflammatory reactions and neutrophil extracellular traps (NETs) formation by polymorphonuclear leukocytes (PMNs) in dairy cows. This model was used to examine the effect of carprofen (CA) on lipopolysaccharide (LPS)-induced NETs formation and expression of inflammatory factors. Peripheral blood samples were collected from 24 Holstein cows (3-11 days postpartum) and PMNs were isolated. In three replicates, PMNs were exposed to various treatments to establish an appropriate in vitro model, including 80 μg/mL of LPS for 2 h, followed by co-incubation for 1 h with 60 μmol/L CA and 80 μg/mL LPS. The effects of these treatments were evaluated by assessing NETs formation by extracellular DNA release, gene expression of pro-
