Application

Acetyl-β-methylcholine (methacholine), an analog of acetylcholine, is use as a receptor agonist to study processes such as airway hyperresponsiveness associated with asthma.

Actions biochimiques/physiologiques

Metabolically stable analog of acetylcholine; muscarinic agonist. Its ability to constrict airway smooth muscle is used to assess bronchial reactivity in the laboratory and clinically.

The great advances of nanomaterials have brought out broad important applications, but their possible nanotoxicity and risks have not been fully understood. It is confirmed that exposure of environmental particulate matter (PM), especially ultrafine PM, are responsible for many lung

Airway responsiveness to methacholine and other bronchoconstrictors is highly variable within and among species. The aim of the experiments in this report was to evaluate the importance of the quantity of airway smooth muscle as a determinant of intra- and

Zona pellucida binding protein 2 (Zpbp2) and ORMDL sphingolipid biosynthesis regulator 3 (Ormdl3), mapped downstream of Zpbp2, were identified as two genes associated with airway hyper-responsiveness (AHR). Ormdl3 gene product has been shown to regulate the biosynthesis of ceramides. Allergic

The typical pathological features of asthma are airway remodeling and airway hyperresponsiveness (AHR). KyoT2, a negative modulator of Notch signaling, has been linked to asthma in several previous studies. However, whether KyoT2 is involved in the regulation of airway remodeling
Alessandro Marcon et al.
The Journal of allergy and clinical immunology, 133(1), 104-110 (2013-05-21)
Evidence on the longitudinal association of airway responsiveness with respiratory diseases is scarce. The best indicator of responsiveness is still undetermined. We investigated the association of airway responsiveness with the incidence of asthma, chronic obstructive pulmonary disease (COPD), and allergic
