Endogenous Isoquinoline Alkaloids Agonists of Acid-Sensing Ion Channel Type 3

Frontiers in Molecular Neuroscience, 2017
Acid-sensing ion channels (ASICs) ASIC3 expressed mainly in peripheral sensory neurons play an important role in pain perception and inflammation development. In response to acidic stimuli, they can generate a unique biphasic current. At physiological pH
