Calcium channels in lymphocytes [PDF]
Immunology, 2001 On B and T lymphocytes, ligation of the antigen receptor (AgR) induces a biphasic Ca2+ response. In the initial phase there is a large elevation in the intracellular Ca2+ concentration as a consequence of Ca2+ release from intracellular stores. This is followed by a lower, but prolonged elevation that is dependent on extracellular Ca2+.1,2 This simple ...

Small-molecule CaVα1⋅CaVβ antagonist suppresses neuronal voltage-gated calcium-channel trafficking [PDF]
, 2018 Extracellular calcium flow through neuronal voltage-gated CaV2.2 calcium channels converts action potential-encoded information to the release of pronociceptive neurotransmitters in the dorsal horn of the spinal cord, culminating in excitation of the ...

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,

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.

Catechol estrogens stimulate insulin secretion in pancreatic β-cells via activation of the transient receptor potential A1 (TRPA1) channel [PDF]
, 2019 Estrogen hormones play an important role in controlling glucose homeostasis and pancreatic β-cell function. Despite the significance of estrogen hormones for regulation of glucose metabolism, little is known about the roles of endogenous estrogen ...

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 ...

Tissue-specific expression of calcium channels [PDF]
, 1993 The high-voltage-activated calcium channel is a multimeric protein complex containing 1, 2/δ, β, and γ subunits. The 1 subunit is the ion conduction channel and contains the binding sites for calcium channel blockers and toxins.

Human sperm ion channel (dys)function:implications for fertilization [PDF]
, 2019 BACKGROUND: Intensive research on sperm ion channels has identified members of several ion channel families in both mouse and human sperm. Gene knock-out studies have unequivocally demonstrated the importance of the calcium and potassium conductances in ...
