Tweeters and Woofers: The Complex Orchestra of Calcium Currents in T Lymphocytes

Frontiers in Immunology, 2015
Elevation of intracellular calcium ion (Ca2+) levels is a vital event that regulates T lymphocyte homeostasis, activation, proliferation, differentiation, and apoptosis.

L‐type calcium channel as a cardiac oxygen sensor [PDF]

Annals of the New York Academy of Sciences, 2010
Acute oxygen sensing in the heart is thought to occur through redox regulation and phosphorylation of membrane channels. Here we report a novel O2‐sensing mechanism involving the C‐terminus of the L‐type Ca2+ channel and regulated by PKA phosphorylation. In patch‐clamped myocytes, oxygen deprivation decreased ICa within 40 s.

Developmental Regulation of Small-Conductance Ca²⁺-Activated K⁺ Channel Expression and Function in Rat Purkinje Neurons [PDF]

, 2002
Calcium transients play an important role in the early and later phases of differentiation and maturation of single neurons and neuronal networks. Small-conductance calcium-activated potassium channels of the SK type modulate membrane excitability and ...

Neuroprotective effects of blockers for T-type calcium channels

Molecular Neurodegeneration, 2009
Cognitive and functional decline with age is correlated with deregulation of intracellular calcium, which can lead to neuronal death in the brain.

The Role of L-type Voltage Gated Calcium Channels in Ovarian Cancer [PDF]

, 2021
Ovarian cancer is the most lethal gynaecological malignancy. Of the four ovarian cancer subtypes - serous, mucinous, endometroid and clear cell - serous ovarian cancer is the most common, comprising around 70% of cases.

L-type calcium channel auto-regulation of transcription [PDF]

Cell Calcium, 2011
L-type calcium channels (LTCC) impact the function of nearly all excitable cells. The classical LTCC function is to mediate trans-sarcolemmal Ca(2+) flux. This review focuses on the contribution of a mobile segment of the LTCC that regulates ion channel function, and also serves as a regulator of transcription in the nucleus.

Inhibition of Contractility of Isolated Caprine Detrusor by the Calcium Channel Blocker Cilnidipine and Reversal by Calcium Channel Openers

Current Therapeutic Research, 2023
: Background: Cilnidipine is a fourth-generation calcium channel blocker that is clinically used to treat hypertension. It is a dihydropyridine that blocks L- and N-type calcium channels.

Inactivation of L-type calcium channel modulated by HCN2 channel

American Journal of Physiology-Cell Physiology, 2010
Ca2+ entry is delicately controlled by inactivation of L-type calcium channel (LTCC) composed of the pore-forming subunit α1C and the auxiliary subunits β1 and α2δ. Calmodulin is the key protein that interacts with the COOH-terminal motifs of α1C, leading to the fine control of LTCC inactivation. In this study we show evidence that a hyperpolarization-

The L-type calcium channel in the heart: the beat goes on [PDF]

Journal of Clinical Investigation, 2005
Sydney Ringer would be overwhelmed today by the implications of his simple experiment performed over 120 years ago showing that the heart would not beat in the absence of Ca2+. Fascination with the role of Ca2+ has proliferated into all aspects of our understanding of normal cardiac function and the progression of heart disease, including induction of ...

Regulation by L-Type Calcium Channels of Endocytosis: An Overview

Journal of Molecular Neuroscience, 2012
The exocytotic neurotransmitter release process is tightly coupled to the membrane retrieval (endocytosis) process since both are calcium-dependent processes. For instance, at the adrenal chromaffin cells, catecholamine release is regulated by Ca(2+) entry through L, N and PQ subtypes of voltage-dependent calcium channels (VDCC).
