a) Overall picture of the nerve endings/fibers (arrows) immunodetected with PGP9.5 at time T0 in bronchial biopsies of a patient with asthma. e: Bronchial Epithelium (green); S: Bronchial Submucosa (blue); M: Bronchial Muscle (red). b) Bronchial biopsy at T1. c) Bronchial biopsy at T2. d) Bronchial biopsy at T12. Note the scarcity of nerve fibers in the submucosa and muscle bundles at T1 to T12
