Imaging large cohorts of single ion channels and their activity [PDF]

, 2013
As calcium is the most important signaling molecule in neurons and secretory cells, amongst many other cell types, it follows that an understanding of calcium channels and their regulation of exocytosis is of vital importance.

Suramin-Induced Neurotoxicity: Preclinical Models and Neuroprotective Strategies

Molecules, 2018
Suramin is a trypan blue analogon originally developed to treat protozoan infections, which was found to have diverse antitumor effects. One of the most severe side effects in clinical trials was the development of a peripheral sensory-motor ...

Store-operated calcium channels in skin

Frontiers in Physiology, 2022
The skin is a complex organ that acts as a protective layer against the external environment. It protects the internal tissues from harmful agents, dehydration, ultraviolet radiation and physical injury as well as conferring thermoregulatory control ...

Junctate is a key element in calcium entry induced by activation of InsP3 receptors and/or calcium store depletion [PDF]

, 2004
In many cell types agonist-receptor activation leads to a rapid and transient release of Ca(2+) from intracellular stores via activation of inositol 1,4,5 trisphosphate (InsP(3)) receptors (InsP(3)Rs).

Activation of Calcium Channels

Biophysical Journal, 1984
Activation of Ca channels has been described as a Hodgkin-Huxley process in which the time constants have ratios of two or greater (1, 2, 3) or as a three-state linear sequential process with two very different time constants (4). We examined activation by measuring the turn-on and turn-off of macroscopic Ca currents and the discharge of single Ca ...

Vacuolar calcium channels [PDF]

Journal of Experimental Botany, 2007
The central vacuole is the largest Ca2+ store in a mature plant cell. Ca2+ release from this store contributes to Ca2+-mediated intracellular signalling in a variety of physiological responses. However, the routes for vacuolar Ca2+ release are not well characterized.

Functional implications of calcium permeability of the channel formed by pannexin 1. [PDF]

, 2006
Although human pannexins (PanX) are homologous to gap junction molecules, their physiological function in vertebrates remains poorly understood. Our results demonstrate that overexpression of PanX1 results in the formation of Ca(2+)-permeable gap ...

Pancreatic β Cell CaV Channels in Health and Disease

, 2022
Multiple types of voltage-gated calcium (CaV) channels including CaV1.2, CaV1.3, CaV2.1, CaV2.2, CaV2.3, CaV3.1, and CaV3.2 operate in electrically excitable β cells under both physiological and pathophysiological conditions.

TRP channels in microglia: role in physiology and disease

Frontiers in Cellular Neuroscience, 2015
Microglia are responsible for modulating the cellular environment in the nervous system, where they have neuroprotective effects. In these cells has been reported the expression of different ion channels, including those belonging to the transient ...
