This study aimed to investigate the role of M3 acetylcholine receptor (M3-AChR) expression in airway remodeling. Additionally, we aimed to evaluate the effects of ipratropium bromide solution inhaled in an early phase of asthma on airway remodeling in ovalbumin (OVA)-sensitized and challenged mice. Thirty BALB/c mice were divided into three groups, namely, control group (saline sensitized/challenged mice), asthma group (OVA sensitized/challenged mice), and treatment group (OVA sensitized/challenged mice treated by ipratropium bromide). Pathological changes were detected by histological staining in the bronchopulmonary tissue of mice. WAt/Pbm (the airway wall area /basement membrane perimeter) ratio of the asthma group (25.37 ± 4.25) increased significantly (P 3-AChR concentration increased in the treatment group (29.24 ± 3.59) and was significantly different (P 3-AChR in bronchial walls of asthmatic murine model.
