We recently found that the Acid Sensing Ion Channel, ASIC contributes to synaptic plasticity, learning and memory. ASIC is one of three mammalian members of the DEG/ENaC cation channel family in mammals that are transiently activated by low extracellular pH. ASIC channels are voltage-insensitive and share a large extracellular domain thought to serve as a receptor for extracellular stimuli. Disrupting ASIC in mice eliminated acid-evoked cation currents in central neurons and led to impaired hippocampal long-term potentiation (LTP), learning and memory. Our current research focuses on identifying the mechanism for ASIC activation in vivo, understanding the role of ASIC in synaptic plasticity, and establishing an uninterrupted link between ASIC channel activity and its behavioral impact.
