Primary human atrial cardiomyocytes were patched to analyze mean current-voltage relationships of pacemaker current (If) before and after ivabradine superfusion (1 μmol/L, 7 min). Ivabradine significantly reduced pacemaker current density (pA/pF) from − 80 to − 130 mV (shown in Image).

Peripheral sensitization is the reduction in the threshold of excitability of sensory neurons that results in an augmented response to a given external stimulus. This poster outlines the excitatory and inhibitory signaling pathways involved in modulation of peripheral sensitization. The role of ion channels, GPCRs, neurotrophins, and cytokines in sensory neurons are also described.
