AbstractChronic and uncontrollable cough is one of the most common and debilitating symptoms found in patients with chronic airway diseases. The physical trauma and stresses of chronic cough on the airway mucosa and respiratory muscles can further worsen the deteriorating process of the airway diseases. The articles presented in this section focus primarily on the effect of chronic cough on the cell structure and protective function of the airway mucosa, the mechanisms underlying the hypersensitivity of chronic cough, and new target areas for antitussive drug development. A major emphasis has been placed on the neuronal plasticity found at the peripheral and central sites of the neural pathway mediating the cough reflex, and its potential role in the development of chronic cough is discussed. A number of new and important questions concerning the physiological and pharmacological mechanisms underlying chronic cough have emerged in these presentations. Further studies are required to answer these questions, which should bring a better understanding of the pathogenic mechanisms of chronic cough and lead to the development of new therapeutic strategies.
