Airway structural components drive airway smooth muscle remodeling in asthma.
Chronic asthma is an inflammatory airways disease characterized by pathological changes in the airway smooth muscle (ASM) bundle that contribute to airway obstruction and hyperresponsiveness. Remodeling of the ASM is associated with an increased smooth muscle mass, involving components of cellular hypertrophy and hyperplasia, and changes in the phenotype of the muscle that facilitate proliferat...
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...
متن کاملAirway Smooth Muscle Hypercontractility in Asthma
In recent years, asthma has been defined primarily as an inflammatory disorder with emphasis on inflammation being the principle underlying pathophysiological characteristic driving airway obstruction and remodelling. Morphological abnormalities of asthmatic airway smooth muscle (ASM), the primary structure responsible for airway obstruction seen in asthma, have long been described, but surpris...
متن کاملEBM84 attenuates airway inflammation and mucus hypersecretion in an ovalbumin-induced murine model of asthma.
EBM84 is a traditional herbal medicine and a combination of extracts obtained from Pinellia ternata and Zingiber officinale. It is traditionally used to treat vomiting, nausea, sputum and gastrointestinal disorders, and functions is an effective expectorant. In this study, we evaluated the protective effects of EBM84 on asthmatic responses, particularly mucus hypersecretion in an ovalbumin (OVA...
متن کاملMechanotransduction, asthma, and airway smooth muscle.
Excessive force generation by airway smooth muscle is the main culprit in excessive airway narrowing during an asthma attack. The maximum force the airway smooth muscle can generate is exquisitely sensitive to muscle length fluctuations during breathing, and is governed by complex mechanotransduction events that can best be studied by a hybrid approach in which the airway wall is modeled in sil...
