Conformational changes in the lower palm domain of ASIC1a contribute to desensitization and RFamide modulation. [PDF]

open access: yesPLoS ONE, 2013
Acid-sensing ion channel 1a (ASIC1a) is a proton-gated cation channel that contributes to fear and pain as well as neuronal damage following persistent cerebral acidosis.

ASIC1a activation by amitriptyline and FMRF-amide is removed by serine proteases [PDF]

open access: yesChannels, 2008
Analgesia induced by certain tricyclic antidepressants has been largely used for decades, yet the mechanisms involved are incompletely understood. Starting from previously reported dual effects of amitriptyline on wild-type ENaC (Pena F, et al. J Pharm Pharmacol 54:1393-8: 2002), we extended our study to ASIC1a by performing a series of whole cell and ...

Epilepsy: Molecular Pathogenesis and Emerging Therapies

open access: yesMedComm, Volume 7, Issue 4, April 2026.
Progress has been made in the molecular pathogenesis of epilepsy, revealing multiple therapeutic targets. Recent advances in pharmacology, materials science, and surgical technique, coupled with progress in targeted therapy and disruptive epilepsy network technology, have led to the emergence of innovative strategies for epilepsy treatment.

Molecular basis of inhibition of acid sensing ion channel 1A by diminazene. [PDF]

open access: yesPLoS ONE, 2018
Acid-sensing ion channels (ASICs) are trimeric proton-gated cation permeable ion channels expressed primarily in neurons. Here we employed site-directed mutagenesis and electrophysiology to investigate the mechanism of inhibition of ASIC1a by diminazene.

Dual contribution of ASIC1a channels in the spinal processing of pain information by deep projection neurons revealed by computational modeling.

open access: yesPLoS Computational Biology, 2023
Dorsal horn of the spinal cord is an important crossroad of pain neuraxis, especially for the neuronal plasticity mechanisms that can lead to chronic pain states. Windup is a well-known spinal pain facilitation process initially described several decades

Independent Contribution of Extracellular Proton Binding Sites to ASIC1a Activation [PDF]

open access: yesJournal of Biological Chemistry, 2013
Acid-sensing ion channels (ASICs) are a group of trimeric cation permeable channels gated by extracellular protons that are mainly expressed in the nervous system. Despite the structural information available for ASIC1, there is limited understanding of the molecular mechanism that allows these channels to sense and respond to drops in extracellular pH.

Myophosphorylase Knock Out Prevents the Exaggerated Exercise Pressor Reflex in Rats With Simulated Peripheral Artery Disease

open access: yesActa Physiologica, Volume 242, Issue 3, March 2026.
ABSTRACT Aim Controversy exists on which metabolites determine the exaggerated exercise pressor reflex (EPR) in peripheral artery disease (PAD). In decerebrated rats, we investigated the role played by lactate and hydrogen ions in a model of PAD, which was simulated by ligating the femoral artery for 72 h before the start of the experiment.

Genetic deletion of ASIC3 alters left ventricular remodeling and autonomic function after myocardial infarction in mice

open access: yesPhysiological Reports, Volume 14, Issue 5, March 2026.
Abstract Cardiac afferent neurons have been shown to trigger overactivation of neurohormonal systems known to drive adverse cardiac remodeling following myocardial infarction (MI). Acid‐sensing ion channels (ASICs) that are highly expressed in cardiac sympathetic afferents sense ischemia‐induced myocardial acidosis.

NMDAR-Mediated Hippocampal Neuronal Death is Exacerbated by Activities of ASIC1a [PDF]

open access: yesNeurotoxicity Research, 2015
NMDARs and ASIC1a both exist in central synapses and mediate important physiological and pathological conditions, but the functional relationship between them is unclear. Here we report several novel findings that may shed light on the functional relationship between these two ion channels in the excitatory postsynaptic membrane of mouse hippocampus ...

Coexpression of ASIC2a with ASIC1a generates increased currents.

open access: yes, 2014
A, Representative acid-evoked currents generated by pH 4 application to CHO cells transfected with the indicated ASIC subunits. Coexpressed ASICs were expressed at half the normal amount to keep total ASIC cDNA constant.
