Quercetin treatment decreases chemokine and cytokine levels in elastase/LPS exposed mice. Mice exposed to elastase/LPS were orally gavaged with vehicle or quercetin as described. A to F. Elastase/LPS exposed mice show increased levels of KC, MIP2, MCP-1, IL-1β, IL-12p40 and MIP-1β compared to control naïve mice. Quercetin treatment reduces all the examined cytokines and chemokines. Data represent mean and SEM (n = 10, *different from PBS/vehicle group, p≤0.05; † different from vehicle-treated elastase/LPS exposed mice, p≤0.05 one-way ANOVA).
