Mechanisms of Action of the Peptide Toxins Targeting Human and Rodent Acid-Sensing Ion Channels and Relevance to Their In Vivo Analgesic Effects

Toxins 2022 Oct 17;14(10):709.doi: 10.3390/toxins14100709. Clément Verkest, Miguel Salinas, Sylvie Diochot, Emmanuel Deval, Eric Lingueglia, Anne Baron Abstract Acid-sensing ion channels (ASICs) are voltage-independent H+-gated cation channels largely expressed in the nervous system of rodents and humans. At least six isoforms (ASIC1a, 1b, 2a, 2b,
