Presynaptic calcium channels [PDF]
Neuroscience Research, 2018 Presynaptic Ca2+ entry occurs through voltage-gated Ca2+ (CaV) channels which are activated by membrane depolarization. Depolarization accompanies neuronal firing and elevation of Ca2+ triggers neurotransmitter release from synaptic vesicles. For synchronization of efficient neurotransmitter release, synaptic vesicles are targeted by presynaptic Ca2 ...

Mechanism of calcium permeation in a glutamate receptor ion channel [PDF]
, 2022 The α-amino-3-hydroxy-5-methyl-4-isoxazolepropionic acid receptors (AMPAR) are neurotransmitter-activated cation channels ubiquitously expressed in vertebrate brains.

The ER calcium channel Csg2 integrates sphingolipid metabolism with autophagy
Nature Communications, 2023 Sphingolipids are ubiquitous components of membranes and function as bioactive lipid signaling molecules. Here, through genetic screening and lipidomics analyses, we find that the endoplasmic reticulum (ER) calcium channel Csg2 integrates sphingolipid ...

Calcium channel blockers- Induced iatrogenic gingival hyperplasia: Case series
Journal of Pharmacy and Bioallied Sciences, 2023 Hypertension rightfully termed as “Silent killer” is associated with increase in morbidity and mortality when left untreated. Calcium channel blockers are the most commonly prescribed first-line anti-hypertensive drugs in India.

Mitogens and Calcium Channels [PDF]
Physiology, 1997 Mitogens and, in particular, growth factors can induce changes in free intracellular Ca2+ concentration by opening voltage-independent cationic channels, with different degrees of Ca2+ selectivity. Recent work has provided preliminary insights into the nature of these channels and their role in the control of cell cycle progression.

Cholesterol influences voltage-gated calcium channels and BK-type potassium channels in auditory hair cells. [PDF]
PLoS ONE, 2011 The influence of membrane cholesterol content on a variety of ion channel conductances in numerous cell models has been shown, but studies exploring its role in auditory hair cell physiology are scarce.

Medicine, 2003 Overdose of calcium channel blockers is potentially lethal. Verapamil and diltiazem are much more dangerous than dihydropyridines. Hypotension with (verapamil and diltiazem) or without (dihydropyridines) heart block and bradycardia are the most important features.

A change in configuration of the calmodulin-KCNQ channel complex underlies Ca2+-dependent modulation of KCNQ channel activity. [PDF]
PLoS ONE, 2013 All subtypes of KCNQ channel subunits (KCNQ1-5) require calmodulin as a co-factor for functional channels. It has been demonstrated that calmodulin plays a critical role in KCNQ channel trafficking as well as calcium-mediated current modulation. However,
