Angiotensin II Receptor Type 2 Activation Is Required for Cutaneous Sensory Hyperinnervation and Hypersensitivity in a Rat Hind Paw Model of Inflammatory Pain

Short-term AT2 activation is a potent contributor to thermal hypersensitivity, whereas long-term effects (such as hyperinnervation) also contribute to mechanical hypersensitivity. Pharmacologic blockade of AT2 signaling represents a potential therapeutic strategy aimed at biologic mechanisms underlying chronic inflammatory pain.
