Abstract: AIMS Hypoxic pulmonary vasoconstriction (HPV) is a physiological response to alveolar hypoxia that diverts blood flow from poorly ventilated to better aerated lung areas to optimize ventilation-perfusion matching. Yet, the exact sensory and signaling mechanisms…

Abstract: Aims Hypoxic pulmonary vasoconstriction (HPV) redistributes blood flow from poorly ventilated to better aerated areas in the lung, thereby optimizing ventilation-perfusion ratio (V/Q). Pulmonary artery smooth muscle cell (PASMC) contraction in response to hypoxia is…

Abstract: Hypoxic vasoconstriction is a response that is seen in the pulmonary circulation but not in any other vascular bed in the body. By diverting blood flow away from less well-ventilated regions in the lung, it…

Abstract: Perfusion-ventilation matching in the lungs requires AMPK-α1 and AMPK-α2 activation downstream of LKB1. Hypoxia amps AMPK Most arteries in the body vasodilate in response to hypoxia. In contrast, pulmonary arteries constrict in response to hypoxia…

Abstract: RATIONALE Acetazolamide, a carbonic anhydrase inhibitor used for preventing altitude illness attenuates hypoxic pulmonary vasoconstriction (HPV) while improving oxygenation. Methazolamide, an analog of acetazolamide, is more lipophilic, has a longer half-life, and activates a major…

Abstract: Increased activity of the RhoA/Rho kinase (RhoA/ROCK) signaling pathway is a key feature in the development of pulmonary arterial hypertension (PAH) and the associated pulmonary vascular remodeling under various pathophysiological conditions, including chronic hypoxia. Both…

Abstract: We show that genetic deficiency of the reactive oxygen species generating enzyme NADPH oxidase 4 (NOX4) impairs hypoxic pulmonary vasoconstriction in small (25–40 µm) intra-acinar, but not pre-acinar, arteries in murine precision cut lung slices. These…

Abstract: The pulmonary circulation responds to hypoxia with vasoconstriction, a mechanism that helps to adapt to short-lived hypoxic episodes. When sustained, hypoxic pulmonary vasoconstriction (HPV) may become deleterious, causing right ventricular hypertrophy and failure, and contributing…
