Role of the Purinergic P2Y2 Receptor in Pulmonary Hypertension

WebbShear stress is applied parallel to the vessel surface and is generated due to friction of the blood against the vessel wall. The effect of shear stress is borne directly by the endothelial lining of the blood vessel [].Shear stress (τ) is directly proportional to the blood viscosity (µ) and the rate of flow (Q): τ = 4µQ/πr 3, where r = vessel radius. cis refurbished

Pulmonary Stretch Receptors - an overview

WebbPulmonary stretch receptors trigger vagal afferents that lead to termination of inhalation. The medullary respiratory centers send efferent signals out to the intercostal muscles and diaphragm for modulation of the respiratory pattern during both wake and sleep.68 These inflation-deflation reflexes have been referred to as the Hering-Breuer reflex. Webb17 jan. 2024 · Key Points Pulmonary stretch receptors present in the smooth muscle of the airways and the pleura respond to excessive stretching... The Hering–Breuer … WebbP2Y2 activation in type II AECs in the alveolus occurs in response to stretch-induced adenosine-5′-triphosphate (ATP) release, which later, via subsequent activation of P2X4 receptors, results in surfactant release . P2Y receptors were found in the pulmonary arteries of various species. Thus, mRNA expression of P2Y1, P2Y2, P2Y4, P2Y6, ... cis refund for limited companies

Webb23 sep. 2024 · Pulmonary stretch receptors are mechanoreceptors found in the lungs. When the lung expands, the receptors initiate the Hering-Breuer reflex, which reduces the respiratory rate. Increased firing from the stretch receptors also increases production of pulmonary surfactant.

"WebbBaroreceptors (or venoatrial stretch receptors) are pressure sensors found in the right atrium of the heart that sense changes in the volume and pressure of blood returning to the heart. These receptors send signals to the central nervous system via the vagus nerve (10th cranial nerve). Changes in baroreceptor activity may also trigger a reflex ...

Overinflation of the lung stimulates these stretch receptors, whose impulses are conveyed to the … Webb7 juli 2024 · Pulmonary Stretch Reflex and Other Peripheral Reflexes as Input to Respiratory Sinus Arrhythmia. In our study, we maintained the stretch of pulmonary receptors during the respiratory cycle with NIV, but RSA was significantly reduced. We interpreted this finding as the central respiratory drive is the main contributor to RSA.

WebbNervous receptors in the lungs and respiratory tract can be grouped into four general categories. 1. Deep, slowly adapting end-organs, which respond to stretch of the airway wall and have large-diameter myelinated fibres; those in the lungs are responsible for the Breuer-Hering reflex. 2. Endings in … WebbPulmonary arterial hypertension-congenital heart disease (PAH-CHD) is characterized by systemic to pulmonary arterial shunts and sensitively responds to volume overload and stretch of the vascular wall leading to pulmonary vascular remodeling. We hypothesized that the responses of pulmonary artery smooth muscle cells (PASMCs) to mechanical …

WebbThe reflex response that is produced is apnea followed by rapid breathing, bradycardia, and hypotension (pulmonary chemoreflex). The physiologic role of this reflex is uncertain, … WebbIt appears that in diving the decrease in pulmonary stretch receptor activity during apnea, combined with cessation of central inspiratory neuronal drive, is an important integrative mechanism that helps development of the reflex bradycardia of trigeminal, carotid, chemoreceptor, and baroreceptor origin.
