Immunohistochemistry of airway tissue. Distal BECs of snBA samples were stained with a IgG isotype (×200) or b anti-DPP4 antibody. DPP4 expression can be seen in inflammatory cells, and staining is strongest in the BECs. A sample from a stBA patient after 8 months of ICS treatment (c). Semi-quantitative analysis of DPP4 intensity scored on a 4-point scale (d). DPP4 protein expression is significantly higher in snBA (N = 5, respectively). * P < .05, compared with stBA
