Reversible Slow Desensitization of the Acid-Sensing Ion Channel (ASIC) 1a [PDF]
Abstract Among the proton-activated channels of the ASIC family, ASIC1a exhibits a specific tachyphylaxis phenomenon in the form of a progressive decrease in the response amplitude during a series of activations. This process is well known, but its mechanism is poorly understood.

Permeating protons contribute to tachyphylaxis of the acid‐sensing ion channel (ASIC) 1a [PDF]
The homomeric acid‐sensing ion channel 1a (ASIC1a) is a H+‐activated ion channel with important physiological functions and pathophysiological impact in the central nervous system. Here we show that homomeric ASIC1a is distinguished from other ASICs by a reduced response to successive acid stimulations.

Regulation of ASIC channels by a stomatin/STOML3 complex located in a mobile vesicle pool in sensory neurons [PDF]
A complex of stomatin-family proteins and acid-sensing (proton-gated) ion channel (ASIC) family members participate in sensory transduction in invertebrates and vertebrates.

Inhibition of ASIC1a Attenuates Neuronal Pyroptosis and Neuroinflammation Following Traumatic Brain Injury. [PDF]
This study identifies ASIC1a as a key modulator of neuroinflammation following traumatic brain injury. Pharmacological inhibition of ASIC1a mitigates neuronal pyroptosis and improves neurological outcomes, a protective effect closely associated with the downregulation of the NF‐κB/NLRP3 signaling axis.

Identification of the Ca2+ blocking site of acid-sensing ion channel (ASIC) 1: implications for channel gating. [PDF]
Acid-sensing ion channels ASIC1a and ASIC1b are ligand-gated ion channels that are activated by H+ in the physiological range of pH. The apparent affinity for H+ of ASIC1a and 1b is modulated by extracellular Ca2+ through a competition between Ca2+ and H+.

Naked mole-rat cortical neurons are resistant to acid-induced cell death
Regulation of brain pH is a critical homeostatic process and changes in brain pH modulate various ion channels and receptors and thus neuronal excitability.

Proton Sensing on the Ocular Surface: Implications in Eye Pain
Protons reaching the eyeball from exogenous acidic substances or released from damaged cells during inflammation, immune cells, after tissue injury or during chronic ophthalmic conditions, activate or modulate ion channels present in sensory nerve fibers

Tarantula toxins use common surfaces for interacting with Kv and ASIC ion channels
Tarantula toxins that bind to voltage-sensing domains of voltage-activated ion channels are thought to partition into the membrane and bind to the channel within the bilayer.

Human acid-sensing ion channels (ASIC) are ligand-gated ionotropic receptors expressed widely in peripheral tissues as well as sensory and central neurons and implicated in detection of inflammation, tissue injury, and hypoxia-induced acidosis.
