Reflex regulation of airway smooth muscle tone.
Autonomic nerves in most mammalian species mediate both contractions and relaxations of airway smooth muscle. Cholinergic-parasympathetic nerves mediate contractions, whereas adrenergic-sympathetic and/or noncholinergic parasympathetic nerves mediate relaxations. Sympathetic-adrenergic innervation of human airway smooth muscle is sparse or nonexistent based on histological analyses and plays li...
متن کاملMigration of airway smooth muscle cells.
Migration of smooth muscle cells is a process fundamental to development of hollow organs, including blood vessels and the airways. Migration is also thought to be part of the response to tissue injury. It has also been suggested to contribute to airways remodeling triggered by chronic inflammation. In both nonmuscle and smooth muscle cells numerous external signaling molecules and internal sig...
متن کاملAirway smooth muscle relaxation.
Bronchodilators are important agents in the treatment of asthma and chronic obstructive airways disease. Beta agonists, theophyllines, and antimuscarinic agents are the main drugs in current use, but others are under investigation. Although other actions may be important, these drugs produce bronchodilation either by a direct effect on airway smooth muscle or by inhibiting neural pathways. As o...
متن کاملInhibition of airway smooth muscle tone by Chinese herbal medicines.
The aim of the present study was to elucidate whether Chinese traditional herbal drugs, Gorei-San (TJ-17) and Toki-Shakuyaku-San (TJ-23), affect airway smooth muscle tone and, if so, to determine what the mechanism of action is. Rabbit tracheal segments were isolated and the contractile responses to electrical field stimulation and acetylcholine were measured before and after the application of...
متن کاملAirway smooth muscle and asthma.
The airway smooth muscle is the key determinant of airway narrowing in asthma but its function in the absence of disease is unknown. Evidence for an intrinsic abnormality in the muscle in asthma is only just emerging. The airway smooth muscle is not merely a contractile cell, but also one which determines the composition of, and interacts with the extracellular matrix, and which may participate...
