Abstract

Highlights: Neuropathic pain is a chronic condition that represents a major health problem. There is a need for new medications with greater efficacy and less adverse effects. TRP channels are emerging targets for neuropathic pain therapeutics. Abstract : Neuropathic pain caused by disease or dysfunction of the nervous system is one of the most difficult pain conditions to treat. Symptoms include a hypersensitivity to mechanical and thermal stimuli, processed by specialized nociceptors that constitute the first line of defence of the somatosensory system. The detection of these stimuli depends on the TRP ion channel family, which activates upon damaging pressure, extreme temperature, or toxic endogenous and exogenous chemicals. This review will summarize the current knowledge of the contribution of TRP channels, particularly the thermosensitive TRP, including TRPV1, TRPA1 and TRPM8 channels that play a central role in the sensitization of nociceptive transduction. We will discuss the pharmacology of these receptors and their relative success in preclinical and clinical studies.
