A numerical approach to ion channel modelling using whole-cell voltage-clamp recordings and a genetic algorithm.

PLoS Computational Biology, 2007
The activity of trans-membrane proteins such as ion channels is the essence of neuronal transmission. The currently most accurate method for determining ion channel kinetic mechanisms is single-channel recording and analysis.

Extracellular Vesicle‐Delivered tRF‐His‐GTG‐1 Reprograms Neutrophil Lipophagy and Triggers Inflammation in COVID‐19

Advanced Science, EarlyView.
This study identifies platelet‐derived extracellular vesicles as key immunometabolic regulators in COVID‐19. The delivery of tRF‐His‐GTG‐1 to neutrophils activates TLR8mTOR signaling, disrupts lipophagy, and amplifies NET‐mediated inflammation. Importantly, targeting this axis restores neutrophil homeostasis, offering a potential therapeutic strategy ...

Voltage‐gated potassium channel antibodies in limbic encephalitis

Annals of Neurology, 2003
AbstractWe found voltage‐gated potassium channel (VGKC) antibodies in 4 of 15 patients with limbic encephalitis (LE). Two patients with idiopathic LE had high VGKC antibody levels (>800pM; controls <100pM), that fell in parallel with a clinical response to immunotherapy.

Effect of Crude Extract from the Sea Anemone Bunodeopsis globulifera on Voltage-Gated Ion Channels from Central and Peripheral Murine Nervous Systems

Pharmaceuticals
Sea anemones are an important source of bioactive compounds with potential pharmacological applications. Their toxins are produced and stored in organelles called nematocysts and act on specific targets, including voltage-gated ion channels. To date, sea

Voltage-independent SK-channel dysfunction causes neuronal hyperexcitability in the hippocampus of Fmr1 knock-out mice [PDF]

, 2019
Neuronal hyperexcitability is one of the major characteristics of fragile X syndrome (FXS), yet the molecular mechanisms of this critical dysfunction remain poorly understood. Here we report a major role of voltage-independent potassium (

Microglial HVCN1 Deficiency Improves Movement and Survival of SOD1G93A ALS Mice by Enhancing Microglial Migration and Neuroprotection

Advanced Science, EarlyView.
Hydrogen voltage gated channel 1 (HVCN1) is upregulated in microglia of both ALS patients and its mouse model. HVCN1 deficiency enhances microglial migration via suppressing Akt signaling, promotes neurotrophic capacity and motor function, and prolongs survival of the SOD1G93A ALS mice. This study identifies HVCN1 as a novel, promising druggable target
