Figure 4From: Inhaled corticosteroids inhibit substance P receptor expression in asthmatic rat airway smooth muscle cells Immunocytochemical analysis of NK-1R protein expression in ASMCs from different groups. A: Representative control group cell; B: Representative asthmatic group cell; C: Representative budesonide treatment group cell. The expression of NK-1R in the asthmatic group (Figure 4B) was significantly higher than that in the control group (P < 0.05; Figure 4A) but significantly lower than that in the budesonide treatment group (P < 0.05; Figure 4C).Back to article page
