Fig. 1From: Sensing acidosis: nociception or sngception?Molecular determinants that sense tissue acidosis. Proton-sensing ion channels and/or receptors expressed in nociceptors include members of acid-sensing ion channels (ASICs), transient receptor potential (TRP) channels, two-pore potassium channels (K2Ps), and protein-sensing G-protein-coupled receptors such as G2A, GRP4, OGR1, and TDAG8Back to article page
