Propagation of fast and slow intercellular Ca2+ waves in primary cultured arterial smooth muscle cells

Jean-Jacques Meister, Jean-Louis Bény, Nadia Halidi

Smooth muscle contraction is regulated by changes in cytosolic Ca2+ concentration (Ca2+). In response to stimulation, Ca2+ increase in a single cell can propagate to neighbouring cells through gap junctions, as intercellular Ca2+ waves. To investigate ...

Calcium Dynamics and Intercellular Communication in Arterial Smooth Muscle Cells in Vitro

Nadia Halidi

Tissue blood flow is controlled by changes in the diameter of the arteries and arterioles through coordinated contraction and relaxation of smooth muscle cells (SMCs) within the vascular wall. The contraction of SMCs is primarily regulated by the intracell ...

Implication of the JNK pathway in a rat model of Huntington's disease

Patrick Aebischer, Nicole Déglon

Huntington's disease (HD) is a neurodegenerative disorder resulting from the expansion of a glutamine repeat (polyQ) in the N-terminus of the huntingtin (htt) protein. Expression of polyQ-containing proteins has been previously shown to induce various cell ...

Investigation of novel calcium-related events as suspected contributors to neurodegeneration

Nikita Rudinskiy

Calcium regulates neuronal signaling and viability through a vast range of cellular and molecular mechanisms. However, many details of these mechanisms still remain to be elucidated. It is believed that calcium-related pathways may comprise promising thera ...

Phorbol esters modulate spontaneous and Ca2+-evoked transmitter release via acting on both munc13 and protein kinase C

Ralf Schneggenburger, Natalya Korogod

Diacylglycerol (DAG) and phorbol esters strongly potentiate transmitter release at synapses by activating protein kinase C (PKC) and members of the Munc13 family of presynaptic vesicle priming proteins. This PKC/Munc13 pathway has emerged as a crucial regu ...

Akt is altered in an animal model of Huntington's disease and in patients

Patrick Aebischer, Valérie Gafner, Nicole Déglon

The insulin-like growth factor I (IGF-1)/Akt pathway plays a crucial role in Huntington's disease by phosphorylating the causative protein, polyQ-huntingtin, and abolishing its toxic properties [Humbert et al. (2002)Dev. Cell, 2, 831-837; Rangone et al. (2 ...

Calcium dynamics and intercellular communication in arterial smooth muscle cells

Mathieu Lamboley

This thesis is a contribution to the field of cellular communication in arteries during vasomotion, i.e. rhythmic and spontaneous diameter oscillations of arteries. Investigating how individual smooth muscle cells (SMCs) and endothelial cells (ECs) calcium ...

Evidence for signaling via gap junctions from smooth muscle to endothelial cells in rat mesenteric arteries: possible implication of a second messenger

Jean-Jacques Meister, Jean-Louis Bény, Roger Sauser, Michèle Koenigsberger, Philippe Pittet, Mathieu Lamboley

We investigated heterocellular communication in rat mesenteric arterial strips at the cellular level using confocal microscopy. To visualize Ca(2+) changes in different cell populations, smooth muscle cells (SMCs) were loaded with Fluo-4 and endothelial ce ...
