Figure Lengend Snippet: Measurement of pro-inflammatory cytokine secretion levels in the co-culture system. Analyses were conducted evaluating ( A ) IL-8 levels in the apical medium (differentiated Caco-2 cells) and ( B ) IL-6 and ( C ) TNF-α levels in the basolateral medium (RAW264.7 cells). Caco-2 cells were pre-treated for 90 min with BD, BFM (1/20, v / v ), and budesonide (1 µM, positive control), as indicated by (+), while absence of treatment is indicated by (−). Subsequently, RAW264.7 macrophages were stimulated with LPS at a concentration of 1 µg/mL for 24 h. Data are expressed as mean ± SD of three experiments conducted in triplicate. Different letters (a–e) indicate statistically significant differences among all groups within each panel ( p < 0.05) (one-way ANOVA followed by Tukey’s test).

Figure Lengend Snippet: Evaluation of pharmacological interactions between budesonide and BFM using CI analysis on different inflammatory markers. Measurements were performed in the apical medium (differentiated Caco-2 cells: IL-8, NOx; RAW264.7 macrophages: IL-6, TNF-α, PGE 2 ) and intracellularly (differentiated Caco-2 cells: iNOS, ROS, occludin; RAW264.7 macrophages: NF-κB p65, COX-2). A CI ratio less than 1 indicates antagonism (–), equal to 1 represents additivity (+), and greater than 1 demonstrates synergy (++). Data are expressed as mean ± SD ( n = 3).
