Potent non-competitive antagonist of neuronal nicotinic ACh receptors (nAChRs). Produces long-lasting inhibition of neuronal nAChRs formed by the combination of the most abundant α and β subunits (i.e. α3, α4 and β2, β4 respectively). Displays little inhibition of muscle-type (α1β1γδ) or α7 receptors.

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.
