CCL5 and infection: Although IL-17A and CCL5 levels were the only cytokines that significantly differed from untreated control in both BaL- and LAI-infected explants, a significant difference between DEX and its RU-486 control was observed also for IL-1β and IL-22 in a pooled analysis of the results of LAI and BaL infection experiments upon adjustment for multiple comparison (pre-infection, Figure 3C and Figure 4C).
