Synaptotagmin increases the dynamic range of synapses by driving Ca2+ - evoked release and by clamping a near-linear remaining Ca2+ sensor

Ralf Schneggenburger, Olexiy Kochubey

Ca2+-evoked transmitter release shows a high dynamic range over spontaneous release. We investigated the role of the Ca2+ sensor protein, Synaptotagmin2 (Syt2), in both spontaneous and Ca2+-evoked release under direct control of presynaptic Ca2+, usin ...

Enduring medial perforant path short-term synaptic depression at high pressure

Michele Giugliano

The high pressure neurological syndrome develops during deep-diving (> 1.1 MPa) involving impairment of cognitive functions, alteration of synaptic transmission and increased excitability in cortico-hippocampal areas. The medial perforant path (MPP), conne ...

A Ca2+ ion selective electrode biosensor in microfluidics to monitor hepatocyte’s activities

Philippe Renaud, Harald Van Lintel, Robert Meissner

Ca2+ plays a crucial role in cell communication. For example, periodical changes in Ca2+ concentration act as cell sig- nals. Intracellular Ca2+ signals have been measured by Ca2+ sensitive fluorescent dye [1]. In this study, extracellular Ca2+ variation w ...

Mechanisms of Propagation of Intercellular Calcium Waves in Arterial Smooth Muscle Cells

Jean-Jacques Meister, Jean-Louis Bény, Dominique Seppey, Michèle Koenigsberger

In rat mesenteric arteries, smooth muscle cells exhibit intercellular calcium waves in response to local phenylephrine stimulation. These waves have a velocity of similar to 20 cells/s and a range of similar to 80 cells. We analyze these waves in a theoret ...

Fluidic microstructuring of alginate hydrogels for the single cell niche

Jürgen Brugger, Philippe Renaud, Thomas Michael Braschler, Kristopher Pataky, Ana Valero, Ludovica Colella

Controlling alginate gel formation by diffusion of Ca2+ ions through a filter barrier, a layer-by-layer deposition technique with resolution on the size scale of a single cell is presented. It offers the possibility of exposing cells under biocompatible co ...

A New Lock-step Mechanism of Matrix Remodelling Based on Subcellular Contractile Events

Jean-Jacques Meister, Boris Hinz, Lara Buscemi Estefanell, Lysianne Follonier Castella

Myofibroblasts promote tissue contractures during fibrotic diseases. To understand how spontaneous changes in the intracellular calcium concentration, Ca2+, contribute to myofibroblast contraction, we analysed both Ca2+ and subcellular contractio ...

Ensuring stability in models of atrial kinetics

Vincent Jacquemet

The membrane kinetics of human atrial myocytes as formulated by Courtemance, Ramierz and Nattel has been studied while focusing on its progression toward stationary solutions during long term repetitive stimulation. An algorithm is presented for finding th ...

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 ...
