LXR priming is dependent on IL-1β. Monocytes were treated as indicated with 2 μM T1317 (LXR agonist), 10 μM GW3965 (LXR agonist), 5 μM GSK2033 (LXR antagonist), 1 μM Diacerein, 10 ng/ml IL-1β, 200 ng/ml IL1RA (IL-1 receptor antagonist) or vehicle for 24 h. (A) mRNA levels of IL-1β, were analyzed by real-time qPCR. (B) 24 h after priming medium was changed and after 24 h resting time supernatant was collected and the level of IL-1β was measured using ELISA. (C–F) cells were kept for 5 days in complete medium and restimulated with 5 μg/ml Pam3cys for 24 h. IL-6 (C–E) and TNFα (F) were measured in the supernatant. Graphs represent mean values ± SD of six individuals in three different experiments. *P < 0.05, **P < 0.01 and ***P < 0.001.
