Ca2+ to the rescue – Ca2+channels and signaling in plant immunity
Plant Science, 2019Ca2+ is a universal second messenger in many signaling pathways in all eukaryotes including plants. Transient changes in [Ca2+]cyt are rapidly generated upon a diverse range of stimuli such as drought, heat, wounding, and biotic stresses (infection by pathogenic and symbiotic microorganisms), as well as developmental cues. It has been known for a while

Biochemistry and Molecular Pharmacology of Ca2+ Channels and Ca2+-Channel Blockers
1988Most of what we now know of the structure of the Ca2+ channel comes from work that has been carried out with skeletal muscle membranes. This is because it was shown a number of years ago that the richest source of receptors for Ca2+ -channel blockers and particularly for l,4-dihydropyridines (DHP) ist the skeletal muscle T-tubule membrane system ...

Rocking and rolling with Ca2+ channels
Trends in Neurosciences, 2001Voltage-sensitive Ca2+ channels are a large family of related heterooligomers that couple cell excitability to intracellular signalling. Recent studies on mice carrying Ca2+ channel mutations, or in which Ca2+ channel subunits have been deleted, have provided important information about the roles carried out by these molecules in cardiovascular ...

The Neuropharmacology of Ca2+ Channels
1988Ion channels that allow the influx of Ca2+ into neurons or other cells have been traditionally divided into two groups: voltage-sensitive Ca2+ channels (VSCC) and receptor-operated channels (ROC). Ca2+ influx via these and other pathways is one method by which an increase in the intracellular free Ca2+ concentration, [Ca2+]i, can be achieved.

[Pharmacological basis of Ca2+ channels and Ca2+ channel antagonists].
Clinical calcium, 2005Ca2+ plays multiple roles in muscle E-C coupling, secretion, and neural transmission, in addition to survival, proliferation, and death of cells. The voltage-dependent L-type Ca2+ channel is a transmembrane protein that selectively permeates Ca2+ on activation by membrane depolarization.

Cell Calcium, 2000
In order to learn about the endogenous Ca2+-buffering in the cytoplasm of chick dorsal root ganglion (DRG) neurons and the distance separating the ryanodine receptor Ca2+ release channels (RyRs) from the plasma membrane, we monitored the amplitude and time course of Ca2+-activated Cl- currents (I(ClCa)) in protocols that manipulated Ca2+-buffering.

Advances in experimental medicine and biology, 2003
The retinal pigment epithelium closely interacts with photoreceptors and helps to maintain the activity of photoreceptors. Investigations using patch-clamp techniques on cultured or freshly isolated retinal pigment epithelial cells from various species demonstrated the expression of voltage-dependent Ca2+ channels with characteristics of L-type ...

Regulation of Ca2+-Release Channels by Luminal Ca2+
1998The intracellular Ca2+-release channels consist of two gene families each represented by three different isoforms with similar properties: the inositol 1,4,5-trisphosphate receptor (InsP3R) family (Furuichi et al., 1994; Joseph, 1996; Missiaen et al., 1996c; Mikoshiba, 1997) and the ryanodine receptor (RyR) family (Sorrentino & Volpe, 1993; McPherson &
