Figure 2. Palmitic acid induces but Docosahexaenoic acid (DHA) inhibits the expression of pro-IL-1β and inflammasome-mediated IL-1β production.
(A and B) THP-1 cells were serum starved in 0.25% FBS-RPMI-1640 for 12 hours. Cells were incubated with DHA for 1 hour then treated with C16:0 (150 µM). (A) After 6 hours cell lysates were immunoblotted for pro-IL-1β and caspase-1. (B) After 24 hours cell culture supernatants were analyzed for IL-1β by immunoblot and ELISA. Secreted caspase-1 was analyzed by immunoblot. Data are expressed as mean ± s.d. and are representative of three independent experiments with similar results.
