Fig. 7From: Dual action of highbush blueberry proanthocyanidins on Aggregatibacter actinomycetemcomitans and the host inflammatory responseEffect of highbush blueberry PACs on the secretion of a MMP-3 and b MMP-9 by macrophages stimulated with A. actinomycetemcomitans LPS. The commercial inhibitor BAY-11-7082 (25 μM) was used as a positive inhibitory control. Results are expressed as the means ± SD of triplicate assays from three independent experiments. Φ: significant increase (p < 0.001) compared to unstimulated control cells. *: significant decrease (p < 0.001) compared to LPS-stimulated cells not treated with highbush blueberry PACsBack to article page
