Primary sensory afferents and their neighboring host-defense cells are a rich source of lipid-derived mediators that contribute to the sensation of pain caused by tissue damage and inflammation. But an increasing number of lipid molecules have been shown to act in an opposite way, to suppress the inflammatory process, restore homeostasis in damaged tissues and attenuate pain sensitivity by regulating neural pathways that transmit nociceptive signals from the periphery of the body to the CNS. Here we review the molecular and cellular mechanisms that contribute to the modulatory actions of lipid mediators in peripheral nociceptive signaling. © 2014 Nature America, Inc.
