Target

NLRP3 inflammasome

In Vitro (±)11(12)-EET (5 μM; 10 mimutes; macrophages) depresses NLRP3 protein expression, dramatically decreases the expression of pro-IL-1β in cells and the supernatant and reduces the intracellular ROS[1]. Western Blot Analysis[1] Cell Line: Macrophages Concentration: 5 μM Incubation Time: 10 mimutes Result: Depresses NLRP3 protein expression. Immunofluorescence[1] Cell Line: Macrophages Concentration: 5 μM Incubation Time: 10 mimutes Result: Reduced the intracellular ROS.
In Vivo (±)11(12)-EET increases adhesion of isolated peripheral blood leukocytes in a chamber coated with P-selectin and ICAM-1 in 50 µg/kg[5].
