Neuronal and ion channel mechanisms of noxious heat sensing in mammals: A puzzle of sensory physiology and pharmacology

open access: yesBritish Journal of Pharmacology, EarlyView.
Transient receptor potential vanilloid 1 (TRPV1) was the first noxious heat‐sensitive channel discovered. In rodents, its role is robust in the heat response of the cell body of polymodal nociceptors, but surprisingly small in that of the peripheral terminals in the skin.

Ion Channel Dysfunction and Therapeutic Targeting in Salivary Gland Disorders

open access: yesOral 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 ...

Structure-Function Analysis of the Anion-Selective Pore of Anoctamin-1 [PDF]

open access: yesBiophysical Journal, 2011
The anoctamins are a newly described family of anion channels. It has been proposed that anoctamin-1 (Ano1) has 8 transmembrane segments (TMDs) with a re-entrant loop between the 5th and 6th TMD that participates in forming the selectivity filter. To clarify the detailed structure and function of this region, we used cysteine accessibility scanning ...

Presynaptic Localization and Possible Function of Calcium-Activated Chloride Channel Anoctamin 1 in the Mammalian Retina. [PDF]

open access: yesPLoS ONE, 2013
Calcium (Ca(2+))-activated chloride (Cl(-)) channels (CaCCs) play a role in the modulation of action potentials and synaptic responses in the somatodendritic regions of central neurons. In the vertebrate retina, large Ca(2+)-activated Cl(-) currents (ICl(

TMEM16A channel signalling microdomains in the regulation of vascular function

open access: yesThe Journal of Physiology, EarlyView.
Abstract figure legend Schematic representation of TMEM16A channel signalling microdomains. Calcium influx or calcium release from the endoplasmic/sarcoplasmic reticulum (ER/SR) activates TMEM16A channels through interactions with regulatory proteins in vascular smooth muscle cells or endothelial cells. TMEM16A channel activation drives chloride efflux,

Anoctamin‐1 is expressed and functional in the Pulmonary Vascular Endothelium

open access: yesThe FASEB Journal, 2013
Background and Objective The expression and functional role of Anoctamin‐1 (ANO1), a Ca2+ activated Cl channel in the endothelial cells (EC) is unclear. We sought to confirm the presence of ANO1 in the pulmonary vascular EC (PVEC) and the effect of ANO1 activation on EC membrane potential (Vm).

Calcium‐activated chloride channels in pericytes and their role in regulating organ blood flow

open access: yesThe 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.

Anoctamin 1, a multi-modal player in pain and itch

open access: yesCell Calcium
Anoctamin 1 (ANO1/TMEM16A) encodes a Ca2+-activated Cl- channel. Among ANO1's many physiological functions, it plays a significant role in mediating nociception and itch. ANO1 is activated by intracellular Ca2+ and depolarization. Additionally, ANO1 is activated by heat above 44 °C, suggesting heat as another activation stimulus.
