SMM-189 treatment reduced the percentage of neutrophils during DSS-induced colitis. Spleens, MLNs, and LPLs were harvested from the three groups of mice described in the legend for Figure 1 and single-cell suspensions were prepared from each tissue. Cells were stained with antibodies specific for the T cell marker CD3 and the neutrophil marker LY6G. Panel (A), CD3− lymphocytes from the spleen, MLNs, or LPLs were screened for the presence of neutrophils (LY6G) by flow cytometry. The percentage in the lower right quadrants of the plots in panel (A) reflects the total neutrophils and is shown in the bar graph of Panel (B). Data represents the total percentage of cells ± SEM from three independent experiments, each involving six mice per group (n = 18). Asterisks (*), indicate statistically significant differences (p < 0.01) between the vehicle (DSS) and SMM-189-treated groups.
