Ion Channel Dysfunction and Therapeutic Targeting in Salivary Gland Disorders
Oral Diseases, EarlyView.ABSTRACT Objective Salivary gland hypofunction and xerostomia represent major clinical complications of radiation therapy, autoimmune disorders such as Sjögren's disease, and inherited epithelial ion transport defects. This review integrates current knowledge on ion channel dysfunction as a central mechanistic driver of salivary gland pathology and ...

Calcium‐activated chloride channels in pericytes and their role in regulating organ blood flow
The Journal of Physiology, EarlyView.Abstract figure legend Pericytes are microvascular mural cells with diverse roles. Contractile pericytes directly regulate local perfusion, while non‐contractile pericytes coordinate upstream vascular contractility via propagating electrical signals.

The STIM1/Orai signaling machinery [PDF]
Channels, 2013 Ca(2+) influx via store-operated Ca(2+) release activated Ca(2+) (CRAC) channels represents a main signaling pathway for T-cell activation as well as mast-cell degranulation. The ER-located Ca(2+)-sensor, STIM1 and the Ca(2+)-selective ion pore, Orai1 in the membrane are sufficient to fully reconstitute CRAC currents.

Target Molecules of STIM Proteins in the Central Nervous System
Frontiers in Molecular Neuroscience, 2020 Stromal interaction molecules (STIMs), including STIM1 and STIM2, are single-pass transmembrane proteins that are located predominantly in the endoplasmic reticulum (ER). They serve as calcium ion (Ca2+) sensors within the ER.

The Journal of Physiology, EarlyView.Abstract figure legend TMEM16A plays a pivotal role in setting the duration of the action potential plateau in human uterine smooth muscle. An increase in TMEM16A expression in labour underpins a lengthening of the plateau and this provides time for the contraction to become larger and longer, important for timely successful labour.

The Journal of Physiology, EarlyView.Abstract figure legend Immunohistochemistry, electrophysiology and pharmacology are useful tools for understanding protein and channel expression and physiological reactions of calcium‐activated chloride channels (CaCCs). Conventional transmission electron microscopy has provided useful 2‐D information on organelle arrangement, localization and ...

Upregulation of Orai Channels Contributes to Aging-Related Vascular Alterations in Rat Coronary Arteries [PDF]
, 2023 Vascular territories display heterogeneous sensitivity to the impacts of aging. The relevance of the STIM/Orai system to vascular function depends on the vascular bed.

The Journal of Physiology, EarlyView.Abstract figure legend The calcium‐activated chloride (ClCa) channel TMEM16A (also known as ANO1) plays critical roles in ion transport, neurotransmission and smooth muscle contraction. Dysregulation of TMEM16A channel activity contributes to the development and progression of various diseases.

The STIM-Orai Pathway: Orai, the Pore-Forming Subunit of the CRAC Channel [PDF]
, 2017 This chapter focuses on the Orai proteins, Orai1-Orai3, with special emphasis on Orai1, in humans and other mammals, and on the definitive evidence that Orai is the pore subunit of the CRAC channel. It begins by reviewing briefly the defining characteristics of the CRAC channel, then discusses the studies that implicated Orai as part of the store ...
