Asthma is a chronic, inflammatory disorder of the airways, with airway remodeling an important contributor to chronic airway obstruction and lung function impairment. Studies in mice have shown that interleukin (IL)-17A is critical for host defense against a number of extracellular and intracellular pathogens; however, little is known regarding its role in allergic inflammation. This study aimed to investigate the effect of IL-17A on the development of pulmonary inflammation and airway remodeling in a murine model of chronic asthma. A BALB/c mouse model of chronic asthma was used to determine the effect of IL-17A on allergic airway inflammation. Mice were sensitized and challenged with ovalbumin to induce airway inflammation, and a neutralizing antibody against IL-17A was administered either before, simultaneously with, or after ovalbumin challenge to determine the timing of IL-17A's effect. BAL was assessed for inflammatory cell infiltration and levels of IL-4, IL-5, and IL-13, and the lungs were assessed for airway remodeling, using morphometric analysis and immunohistochemistry. Airway reactivity to methacholine was measured in naïve mice. IL-17A levels were significantly increased in the bronchoalveolar lavage fluid of mice sensitized and challenged with ovalbumin when compared with control mice. This increase was specific to ovalbumin-induced airway inflammation because total and differential cell counts, eosinophil, neutrophil, and lymphocyte counts, were similar between groups. The number of IL-17A-producing cells was significantly increased in the airways of ovalbumin-sensitized and challenged mice compared with naïve mice, and this was significantly reduced in mice treated with the anti-IL-17A antibody. A neutralizing antibody against IL-17A was able to reverse the recruitment of IL-4, IL-5, and IL-13-producing cells to the airways. Airway reactivity to methacholine was significantly increased in ovalbumin-s ac619d1d87
