Abstract:Treatment of cardiac arrhythmias by targeting ion channels is challenging, with safe and effective therapies remaining an unmet clinical need. Modeling and experimental studies have shown that a voltage-gated sodium channel (VGSC)-rich nanodomain at edge of the gap junction (GJ) called the perinexus could provide new mechanistic insights into normal and abnormal conduction of action potentials in the heart. We have reported that a 19 amino acid SCN1B (β1/β1B) mimetic peptide derived from the immunoglobulin dom… Show more
