Production of ROS. Histograms representative of the effects of different concentrations of SP1 (A) and SP2 (B) on intracellular ROS production quantified by flow cytometry. NC—negative control; LPS—bacterial lipopolysaccharide (2 µg/mL). (C) Percentage of intracellular ROS production in relation to that of LPS-stimulated cells. The data are presented as the mean ± standard deviation (n = 3). Different letters represent statistically significant differences between SPs concentrations (p < 0.01). Different numbers represent statistically significant differences between the same concentrations of different SPs (p < 0.01). * represents samples that had a statistically significant differences in relation to the negative control (p < 0.01).
