Calcium Channels and Calcium-Binding Proteins. [PDF]
Int J Mol Sci, 2023 Signals of nerve impulses are transmitted to excitatory cells to induce the action of organs via the activation of Ca2+ entry through voltage-gated Ca2+ channels (VGCC), which are classified based on their activation threshold into high- and low-voltage activated channels, expressed specifically for each organ [...]

Calcium Permeable Channels in Cancer Hallmarks
Frontiers in Pharmacology, 2020 Cancer, the second cause of death worldwide, is characterized by several common criteria, known as the “cancer hallmarks” such as unrestrained cell proliferation, cell death resistance, angiogenesis, invasion and metastasis.

Calcium Channels: Noteworthy Regulators and Therapeutic Targets in Dermatological Diseases
Frontiers in Pharmacology, 2021 Dysfunctional skin barrier and impaired skin homeostasis may lead to or aggravate a series of dermatologic diseases. A large variety of biological events and bioactive molecules are involved in the process of skin wound healing and functional recovery ...

Pflügers Archiv - European Journal of Physiology, 2018 Tuned calcium entry through voltage-gated calcium channels is a key requirement for many cellular functions. This is ensured by channel gates which open during membrane depolarizations and seal the pore at rest. The gating process is determined by distinct sub-processes: movement of voltage-sensing domains (charged S4 segments) as well as opening and ...

Calcium Channel Blockers [PDF]
The Journal of Clinical Hypertension, 2011 KEY POINTS AND PRACTICAL RECOMMENDATIONS: • Calcium channel blockers, which dilate arteries by reducing calcium flux into cells, effectively lower blood pressure, especially in combination with other drugs, and some formulations of agents of this class are approved for treating angina or cardiac dysrhythmias.

The involvement of TRP channels in bone homeostasis
Frontiers in Endocrinology, 2012 Calcium and bone homeostasis are intimately related. On the one hand, bone relies on a sufficient supply of calcium to maintain its structural and mechanical properties and thus largely depends on calcium absorption in the intestine and calcium ...

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 ...

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 ...
