CellsPacemaking activity in substantia nigra dopaminergic neurons is generated by the coordinated activity of a variety of distinct somatodendritic voltage- and calcium-gated ion channels. We investigated whether these functional interactions could arise from

Ultrasound modulates ion channel currents
Scientific Reports, 2016 Transcranial focused ultrasound (US) has been demonstrated to stimulate neurons in animals and humans, but the mechanism of this effect is unknown. It has been hypothesized that US, a mechanical stimulus, may mediate cellular discharge by activating ...

Ion Channels in Glioblastoma [PDF]
ISRN Neurology, 2011 Glioblastoma is the most common primary brain tumor with the most dismal prognosis. It is characterized by extensive invasion, migration, and angiogenesis. Median survival is only 15 months due to this behavior, rendering focal surgical resection ineffective and adequate radiotherapy impossible. At this moment, several ion channels have been implicated

FEBS Letters, EarlyView.Venom peptides have shown promise in treating pain. Our study uses computer screening to identify a peptide that targets a sodium channel (NaV1.7) linked to chronic pain. We produced the peptide in the laboratory and refined its design, advancing the search for innovative pain therapies.

Ion Channel Reconstitution [PDF]
Biophysical Journal, 2012 Since the discovery of the possible solubilization of membrane proteins and their isolation from other membrane constituents (purification), different methods were developed to reconstitute ion channel proteins into artificial lipid bilayers. These membrane proteins were then fully functional when correctly oriented and inserted in a lipid bilayer. The

Social context prevents heat hormetic effects against mutagens during fish development
FEBS Letters, EarlyView.This study shows that sublethal heat stress protects fish embryos against ultraviolet radiation, a concept known as ‘hormesis’. However, chemical stress transmission between fish embryos negates this protective effect. By providing evidence for the mechanistic molecular basis of heat stress hormesis and interindividual stress communication, this study ...

TRP Channels Regulation of Rho GTPases in Brain Context and Diseases
Frontiers in Cell and Developmental Biology, 2020 Neurological and neuropsychiatric disorders are mediated by several pathophysiological mechanisms, including developmental and degenerative abnormalities caused primarily by disturbances in cell migration, structural plasticity of the synapse, and blood ...

Piezo1 ion channel pore properties are dictated by C-terminal region
Nature Communications, 2015 Piezo1 and Piezo2 encode mechanically activated cation channels that function as mechanotransducers involved in vascular system development and touch sensing, respectively. Structural features of Piezos remain unknown.
