For the inhibition experiments, monocytes were first incubated for 30 min with inhibitors specific for different PRRs' or intracellular proteins before addition of the ulvan extract at 25 μg/ml for 4 h. Data represents the mean ± SEM of five independent experiments in duplicate. Different letters indicate statistically significant differences, ap < 0.05, bp < 0.01, cp < 0.05.
