Calcium regulates three different aspects of cardiac contraction. It drives pacemaker activity, excitation–contraction coupling and the transcriptional events that remodel the Ca2+ signalling system in both health and disease.

Calcium Signaling in the Islets
2010Easy access to rodent islets and insulinoma cells and the ease of measuring Ca(2+) by fluorescent indicators have resulted in an overflow of data that have clarified minute details of Ca(2+) signaling in the rodent islets. Our understanding of the mechanisms and the roles of Ca(2+) signaling in the human islets, under physiological conditions, has been

Cell Calcium, 2011
The placenta sustains the developing fetus throughout gestation and its major functions include nutrition, gas and waste exchange via a variety of passive or active mechanisms. Up to 30 g of calcium (Ca(2+)) actively crosses the trophoblast layer during human pregnancy.

Calcium Signalling in the Endothelium
2006Elevations in cytosolic Ca2+ concentration are the usual initial response of endothelial cells to hormonal and chemical transmitters and to changes in physical parameters, and many endothelial functions are dependent upon changes in Ca2+ signals produced.

Calcium Signaling and Annexins
Cell Biochemistry and Biophysics, 2000The annexins, are a family of calcium ion (Ca2+)-binding proteins whose physiological functions are poorly understood. Although many diverse functions have been proposed for these proteins, such as in vesicle trafficking, this review focuses on their proposed roles as Ca2+ or other ion channels, or as intracellular ion channel regulators.

Calcium is the major intracellular messenger linking synaptic activity in neurons to gene expression to control diverse functions including adaptive responses to synaptic activity as well as survival and death (Bading et al. 1993; Hardingham et al. 1997; Chawla and Bading 2001; West et al. 2001; Zhang et al.

Calcium signalling in astroglia
Molecular and Cellular Endocrinology, 2012Astroglia possess excitability based on movements of Ca(2+) ions between intracellular compartments and plasmalemmal Ca(2+) fluxes. This "Ca(2+) excitability" is controlled by several families of proteins located in the plasma membrane, within the cytosol and in the intracellular organelles, most notably in the endoplasmic reticulum (ER) and ...

Trends in Neurosciences, 1988
very cell in an organism has a specialized task or function. As investigators, we are constantly posing the questions 'How is this function carried out? How is it regulated?' It is now a fundamental tenet of modem biology that small diffusible second messen- ger molecules act within the cell to provide a link between stimulus and output.

Calcium Signaling in the Heart
2019The aim of this chapter is to discuss evidence concerning the many roles of calcium ions, Ca2+, in cell signaling pathways that control heart function. Before considering details of these signaling pathways, the control of contraction in ventricular muscle by Ca2+ transients accompanying cardiac action potentials is first summarized, together with a ...

Calcium signaling in platelets
Journal of Thrombosis and Haemostasis, 2009Agonist-induced elevation in cytosolic Ca2+ concentrations is essential for platelet activation in hemostasis and thrombosis. It occurs through Ca2+ release from intracellular stores and Ca2+ entry through the plasma membrane (PM). Ca2+ store release is a well-established process involving phospholipase (PL)C-mediated production of inositol-1,4,5 ...
