Their cell bodies, located mainly in the trigeminal and dorsal root ganglion (DRG), present sensory innervation to virtually all tissues except the brain parenchyma. Specialized receptors, channels, and synthetic pathways enable define the specificity of particular nociceptor subtypes, allowing the detection and signaling of both acute and persistent (chronic) noxious stimuli. We will concentrate on two principle receptors/channels which have been identified and characterized on nociceptors that detect noxious inflammatory stimuli. The first, transient receptor potential cation channel subfamily V member 1 (TRPV1 previously known asvanilloid receptor 1 [VR1]), was initially reported to function as an integrator of many noxious stimuli by means of the demonstration that diverse products of inflammation, like protons, anandamide, bradykinin, and nerve development issue (NGF), functioned as good modulators or full agonists at TRPV12,3. Solutions with the lipoxygenase pathway of arachidonic acid, 12-(S)-hydroperoxyeicosatetraenoic acid and leukotriene B4, have also been located to activate TRPV1 in vitro, and activated protein kinase C can straight activate or decrease the activation threshold of TRPV1 to thermal stimuli2,four. Two derivatives of dopamine (N-arachidonoyl dopamine and N-oleoyl dopamine) have also been identified to activate TRPV1 and are linked with experimental hyperalgesia9,10 (for overview, see Figure a single as well as 11,12).Dorsal HornFigure 1.
