Muscarinic receptor signaling in the pathophysiology of asthma and COPD

Respiratory Research, 2006
Anticholinergics are widely used for the treatment of COPD, and to a lesser extent for asthma. Primarily used as bronchodilators, they reverse the action of vagally derived acetylcholine on airway smooth muscle contraction.

P2Y₂ Nucleotide Receptors Expressed Heterologously in Sympathetic Neurons Inhibit Both N-Type Ca²⁺ and M-Type K⁺ Currents [PDF]

, 1998
The P2Y₂ receptor is a uridine/adenosine triphosphate (UTP/ATP)-sensitive G-protein-linked nucleotide receptor that previously has been reported to stimulate the phosphoinositide signaling pathway.

Oscillometric assessment of bronchodilator response in horses with severe asthma during remission

Equine Veterinary Journal, EarlyView.
Abstract Background During clinical remission of severe equine asthma (SEA), affected animals can be challenging to distinguish from healthy horses. In humans, the degree of bronchodilation achieved with a β2‐adrenergic bronchodilator is helpful in differentiating asthmatics from healthy subjects.

Muscarinic Receptors and Their Antagonists in COPD: Anti-Inflammatory and Antiremodeling Effects

Mediators of Inflammation, 2012
Muscarinic receptors are expressed by most cell types and mediate cellular signaling of their natural ligand acetylcholine. Thereby, they control numerous central and peripheral physiological organ responses to neuronal activity.

Effects of Single and Multiple Dose Tiotropium/Olodaterol in Chronic Obstructive Pulmonary Disease on Alveolar Gas Exchange Measured by Hyperpolarized 129Xe MRI

Journal of Magnetic Resonance Imaging, EarlyView.
ABSTRACT Background Long‐acting muscarinic antagonists/long‐acting beta adrenoreceptor agonists lead to lung deflation and improved microvascular perfusion in hyperinflated chronic obstructive pulmonary disease (COPD), but with an unclear time course. Purpose To investigate the effect of inhalation of tiotropium/olodaterol (TIO/OLO) on MRI measures of ...

The involvement of cholinergic neurons in the spreading of tau pathology

Frontiers in Neurology, 2013
Long time ago, it was described the selective loss of cholinergic neurons during the development of Alzheimer disease. Recently, it has been suggested that tau protein may play a role in that loss of cholinergic neurons through a mechanism involving the ...

Native Xenopus oocytes express two types of muscarinic receptors [PDF]

, 1991
We have recently described two types of muscarinic responses in native Xenopus oocytes of different donors (common and variant) that display qualitative and quantitative differences (Lupu-Meiri et al., 1990).

Intraoperative Bradycardia: Evaluating Vasovagal Events in Adult Suspension Microlaryngeal Surgery

The Laryngoscope, EarlyView.
This retrospective single‐surgeon cohort study of 190 adults undergoing suspension microlaryngoscopy found that 8.9% (17/190) developed significant intraoperative bradycardia consistent with a vasovagal response (VVR). No demographic, comorbidity, or procedural factors were significantly associated with VVR, though most affected patients required ...
