P2X receptors are membrane ion channels activated by the binding of extracellular
adenosine triphosphate (ATP). For years their functional significance was consigned to
distant regions of the autonomic nervous system, but recent work indicates several further
key roles, such as afferent signalling, chronic pain, and in autocrine loops of endothelial and
epithelial cells. P2X receptors have a molecular architecture distinct from other ion channel
protein families, and have several unique functional properties.
