Pathophysiological Significance of T-type Ca2+ Channels: T-type Ca2+ Channels and Drug Development
T-type Ca2+ channels are present in cardiovascular, neuronal, and endocrine systems; and they are now receiving attention as novel therapeutic targets. Many drugs and compounds non-specificaly block T-type Ca2+ channels. Certain dihydropyridine compounds,

Ca2+ entry through NaV channels generates submillisecond axonal Ca2+ signaling
Calcium ions (Ca2+) are essential for many cellular signaling mechanisms and enter the cytosol mostly through voltage-gated calcium channels. Here, using high-speed Ca2+ imaging up to 20 kHz in the rat layer five pyramidal neuron axon we found that ...

Swelling-activated Ca2+ channels trigger Ca2+ signals in Merkel cells.
Merkel cell-neurite complexes are highly sensitive touch receptors comprising epidermal Merkel cells and sensory afferents. Based on morphological and molecular studies, Merkel cells are proposed to be mechanosensory cells that signal afferents via ...

Ca2+-Sensitive Potassium Channels
The Ca2+ ion is used ubiquitously as an intracellular signaling molecule due to its high external and low internal concentration. Many Ca2+-sensing ion channel proteins have evolved to receive and propagate Ca2+ signals. Among them are the Ca2+-activated

ER localized bestrophin1 activates Ca2+ dependent ion channels TMEM16A and SK4 [PDF]
Bestrophins form Ca2+ activated Cl- channels and regulate intercellular Ca2+ signaling1. We demonstrate that bestrophin 1 is localized in the endoplasmic reticulum (ER), where it physically interacts with stromal interacting molecule 1 (Stim1), the ER ...

TRP Channels Mediated Pathological Ca2+-Handling and Spontaneous Ectopy
Ion channel biology offers great opportunity in identifying and learning about cardiac pathophysiology mechanisms. The discovery of transient receptor potential (TRP) channels is an add-on to the opportunity. Interacting with numerous signaling pathways,
