Quijano J, Vianay B, Beny J, Meister J
Cell Calcium . 2013 Nov; 54(6):436-45. PMID: 24183802
Communication between vascular smooth muscle cells (SMCs) allows control of their contraction and so regulation of blood flow. The contractile state of SMCs is regulated by cytosolic Ca2+ concentration ([Ca2+]i)...

Boittin F, Alonso F, Le Gal L, Allagnat F, Beny J, Haefliger J
Cell Physiol Biochem . 2013 Feb; 31(1):166-78. PMID: 23407022
Background/aims: Smooth muscle tone is controlled by Ca(2+) signaling in the endothelial layer. Mouse endothelial cells are interconnected by gap junctions made of Connexin40 (Cx40) and Cx37, which allow the...

Halidi N, Alonso F, Burt J, Beny J, Haefliger J, Meister J
Cell Commun Adhes . 2012 May; 19(2):25-37. PMID: 22642233
Intercellular Ca(2+) wave propagation between vascular smooth muscle cells (SMCs) is associated with the propagation of contraction along the vessel. Here, we characterize the involvement of gap junctions (GJs) in...

Halidi N, Boittin F, Beny J, Meister J
Cell Calcium . 2011 Sep; 50(5):459-67. PMID: 21920600
Smooth muscle contraction is regulated by changes in cytosolic Ca(2+) concentration ([Ca(2+)](i)). In response to stimulation, Ca(2+) increase in a single cell can propagate to neighbouring cells through gap junctions,...

Marino M, Beny J, Peyter A, Diaceri G, Tolsa J
J Cardiovasc Pharmacol . 2011 Feb; 57(2):154-65. PMID: 21289495
Exposure to perinatal hypoxia results in alteration of the adult pulmonary circulation, which is linked among others to alterations in K(+) channels in pulmonary artery (PA) smooth muscle cells. In...
6.
Formey A, Buscemi L, Boittin F, Beny J, Meister J
Cell Tissue Res . 2011 Jan; 343(3):509-19. PMID: 21243375
Cells with irregular shapes, numerous long thin filaments, and morphological similarities to the gastrointestinal interstitial cells of Cajal (ICCs) have been observed in the wall of some blood vessels. These...

Alonso F, Boittin F, Beny J, Haefliger J
Am J Physiol Heart Circ Physiol . 2010 Aug; 299(5):H1365-73. PMID: 20802140
Upon agonist stimulation, endothelial cells trigger smooth muscle relaxation through the release of relaxing factors such as nitric oxide (NO). Endothelial cells of mouse aorta are interconnected by gap junctions...

Koenigsberger M, Seppey D, Beny J, Meister J
Biophys J . 2010 Jul; 99(2):333-43. PMID: 20643050
In rat mesenteric arteries, smooth muscle cells exhibit intercellular calcium waves in response to local phenylephrine stimulation. These waves have a velocity of approximately 20 cells/s and a range of...

Cederroth C, Zimmermann C, Beny J, Schaad O, Combepine C, Descombes P, et al.
Mol Cell Endocrinol . 2010 Feb; 321(2):152-60. PMID: 20171261
Soy and soy-based products are widely consumed by infants and adult individuals. There has been speculation that the presence of isoflavone phytoestrogens in soybean cause adverse effects on the development...

Seppey D, Sauser R, Koenigsberger M, Beny J, Meister J
Am J Physiol Heart Circ Physiol . 2009 Dec; 298(2):H488-96. PMID: 19966061
Vasomotion consists of cyclic arterial diameter variations induced by synchronous contractions and relaxations of smooth muscle cells. However, the arteries do not contract simultaneously on macroscopic distances, and a propagation...
