Extracellular Adenosine 5'-Triphosphate And Lipopolysaccharide Induce Interleukin-1Β Release In Canine Blood, Mari Spildrejorde, Stephen J. Curtis, Belinda L. Curtis, Ronald Sluyter
Faculty of Science, Medicine and Health - Papers: part A
Binding of extracellular adenosine 5′-triphosphate (ATP) or lipopolysaccharide (LPS) to the damage-associated molecular pattern receptor P2X7 or the pathogen-associated molecular pattern receptor Toll-like receptor (TLR)4, respectively, can induce the release of the pleiotropic cytokine interleukin (IL)-1β in humans and mice. However, the release of IL-1β in dogs remains poorly defined. Using a canine IL-1β enzyme-linked immunosorbent assay, this study investigated whether ATP or LPS could induce IL-1β release in a canine blood-based assay. Short-term incubations (30 min) with ATP induced IL-1β release in LPS-primed canine blood, and this process could be near-completely impaired by the P2X7 antagonist, A438079. In contrast, …
