Vascular Smooth Muscle Modulates Endothelial Control of Vasoreactivity via Reactive Oxygen Species Production through Myoendothelial Communications

• Marie Billaud, Roger Marthan, J. P. Savineau, Christelle Guibert
• PloS one
• 2009

BACKGROUND Endothelial control of vascular smooth muscle plays a major role in the resulting vasoreactivity implicated in physiological or pathological circulatory processes. However, a comprehensive… (More)

A molecular signature in the pannexin1 intracellular loop confers channel activation by the α1 adrenoreceptor in smooth muscle cells

• Marie Billaud, Yu-Hsin Chiu, +13 authors Brant E Isakson
• Science Signaling
• 2015

Both purinergic signaling through nucleotides such as ATP (adenosine 5′-triphosphate) and noradrenergic signaling through molecules such as norepinephrine regulate vascular tone and blood pressure.… (More)

Role of the gap junctions in the contractile response to agonists in pulmonary artery from two rat models of pulmonary hypertension

• Marie Billaud, Diana Dahan, Roger Marthan, J. P. Savineau, Christelle Guibert
• Respiratory research
• 2011

BACKGROUND Pulmonary hypertension (PH) is characterized by arterial vascular remodelling and alteration in vascular reactivity. Since gap junctions are formed with proteins named connexins (Cx) and… (More)

Loss of collectrin, an angiotensin-converting enzyme 2 homolog, uncouples endothelial nitric oxide synthase and causes hypertension and vascular dysfunction.

• Sylvia Cechova, Qing Gui Zeng, +16 authors Thu H Le
• Circulation
• 2013

BACKGROUND Collectrin is an orphan member of the renin-angiotensin system and is a homolog of angiotensin-converting enzyme 2, sharing ≈50% sequence identity. Unlike angiotensin-converting enzyme 2,… (More)

Dehydroepiandrosterone reverses chronic hypoxia/reoxygenation-induced right ventricular dysfunction in rats.

• Eric Dumas de la Roque, Nadége Bellance, +10 authors Michael Fayon
• The European respiratory journal
• 2012

Dehydroepiandrosterone (DHEA) prevents chronic hypoxia-induced pulmonary hypertension and associated right ventricle dysfunction in rats. In this animal model, reoxygenation following hypoxia… (More)

Tumours of the small intestine: Peutz-Jeghers syndrome

Signaling Pathways Linked to Serotonin-Induced Superoxide Anion Production: A Physiological Role for Mitochondria in Pulmonary Arteries

• Nafiisha Genet, Marie Billaud, +6 authors Christelle Guibert
• Front. Physiol.
• 2017

Serotonin (5-HT) is a potent vasoconstrictor agonist and contributes to several vascular diseases including systemic or pulmonary hypertension and atherosclerosis. Although superoxide anion… (More)

Pulmonary artery smooth muscle responses to KCl under normoxic and hypoxic conditions studied by means of a spatial network model

• Marko Gosak, Marko Marhl, Christelle Guibert, Marie Billaud, Etienne Roux
• BCB
• 2010

We study contractile responses and Ca2+ signalization in pulmonary artery smooth muscle cells. Experimental results indicate that the contraction responses to KCl under normoxic conditions are not… (More)

The influence of gap junction network complexity on pulmonary artery smooth muscle reactivity in normoxic and chronically hypoxic conditions.

• Marko Gosak, Christelle Guibert, Marie Billaud, Etienne Roux, Marko Marhl
• Experimental physiology
• 2014

Experiments on intrapulmonary arteries (IPAs) isolated from rats maintained in normoxia and chronic hypobaric hypoxia showed that in normoxia, the IPA contractile sensitivity to KCl was not modified… (More)
