Potent and selective human P2X7 antagonist (KB values are 5 - 7 and > 10,000 nM at hP2X7 and rP2X7 respectively) that is completely without effect at all other P2X subtypes. Inhibits BzATP-mediated calcium influx and inhibits ATP-mediated IL-1β release in vitro (KB values are 15 and 92 nM respectively).

Literature in this Area
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.
