Abstract

Prostaglandin E is classically considered a major mediator of inflammatory pain, by acting on neuronal G protein-coupled EP2 and EP4 receptors. However, the neuronal EP3 receptor, colocalized with EP2 and EP4 receptor, is G protein-coupled and antagonises the pronociceptive prostaglandin E effect. Here we investigated the cellular signalling mechanisms by which the EP3 receptor reduces EP2 and EP4 receptor-evoked pronociceptive effects in sensory neurons.
