چکیده

We study the spreading of calcium-induced calcium release with the stochastic DeYoung-Keizer-model of the inositol 1,4,5-trisphosphate receptor channel. The model shows a transition from isolated release events to steadily propagating waves with increasing IP3 concentration. A state--stochastic backfiring--was found in the regime of steady propagation. The model can be reduced by an adiabatic elimination of the partial differential equation for the Ca(2+) concentration to a lattice of stochastic channel clusters.

Period distributions of intracellular Ca oscillations

The dynamics of cytosolic Ca2+ concentrations is the dynamics of uptake and release by intracellular storage compartments. It was shown in recent years by several modelling studies that fluctuations drive spatial and temporal structures in intracellular Ca2+ dynamics [1, 3]. Fluctuations arise from the random opening and closing of release channels on the membrane of the endoplasmic reticulum. ...

Computational modelling of the initiation and development of spontaneous intracellular Ca2+ waves in ventricular myocytes.

Intracellular Ca(2+) dynamics provides excitation-contraction coupling in cardiac myocytes. Under pathological conditions, spontaneous Ca(2+) release events can lead to intracellular Ca(2+) travelling waves, which can break, giving transitory or persistent intracellular re-entrant Ca(2+) scroll waves. Intracellular Ca(2+) waves can trigger cellular delayed after-depolarizations of membrane pote...

Stochastic properties of Ca(2+) release of inositol 1,4,5-trisphosphate receptor clusters.

Intracellular Ca(2+) release is controlled by inositol 1,4,5-trisphosphate (IP(3)) receptors or ryanodine receptors. These receptors are typically distributed in clusters with several or tens of channels. The random opening and closing of these channels introduces stochasticity into the elementary calcium release mechanism. Stochastic release events have been experimentally observed in a variet...

Modeling stochastic Ca2+ release from a cluster of IP3-sensitive receptors.

We focused our attention on Ca(2+) release from the endoplasmic reticulum through a cluster of inositol(1,4,5)-trisphosphate (IP(3)) receptor channels. The random opening and closing of these receptors introduce stochastic effects that have been observed experimentally. Here, we present a stochastic version of Othmer-Tang model (OTM) for IP(3) receptor clusters. We address the average behavior ...

Agonist-evoked mitochondrial Ca2+ signals in mouse pancreatic acinar cells.

In the present study we have investigated cytosolic and mitochondrial Ca(2+) signals in isolated mouse pancreatic acinar cells double-loaded with the fluorescent probes fluo-3 and rhod-2. Stimulation of pancreatic acinar cells with 500 nm acetylcholine caused release of Ca(2+) from intracellular stores and produced cytosolic Ca(2+) signals in form of Ca(2+) waves propagating from the luminal to...
