The Acid-Sensing Ion Channels (ASIC) are widely expressed in the central and peripheral nervous system and are activated by extracellular acidification. They are involved in increasing number of physiological or pathological functions such as synaptic transmission, synaptic plasticity, learning, memory, fear, depression, epilepsy and...

Acid-Sensing Ion Channels (ASICs) are cation channels activated by extracellular acidification that emerge as potential pharmacological targets in pain and other neurological disorders. Here, we compare the pharmacological modulation of ASIC1a and ASIC3 channels by amiloride and 2-guanidine-4-methylquinazoline (GMQ), two compounds commonly used...

Mambalgins are 57-amino acid peptides isolated from mamba venom. They produce potent analgesic effects in mice against inflammatory pain upon central intrathecal (i.t.), and peripheral local (i.pl.) injections, through inhibition of different ASICs subtypes and involvement of opioid-independent pathways. They produce fewer side effects than...
