    Description / Table of Contents: Zusammenfassung C-Faser Nozizeptoren haben neben ihrer afferenten auch lokale efferente Funktionen, wie Vasodilatation, Plasmaextravasation und die Modulation neuronaler Aktivität, die durch Freisetzung der Neuropeptide Substanz P, Neurokinin A und Calcitonin Gene-Related Peptide (CGRP) an der peripheren Endigung ausgelöst werden. In der Haut der Säugetiere (einschließlich Mensch) ist CGRP der wichtigste Mediator der Flarereaktion. Die Vasodilatation wird beim Schwein durch Aktivierung von spezifischen Hitzenozizeptoren induziert. Bei der Taube wird die antidrome Vasodilatation durch intrinsisch freigesetztes Galanin gehemmt. Plasmaextravasation kann beim Schwein in Hautblasen und mit der Mikrodialyse durch Histaminsuperfusion, nicht aber durch elektrische Stimulation und Capsaicin, ausgelöst werden. Die neurogene Komponente der Histaminantwort (64%) wird durch NK2-Rezeptoren vermittelt und kann durch CGRP moduliert werden. Die genannten Neuropeptide können zur Sensibilisierung und unter bestimmten Bedingungen zur Stimulation von Nozizeptoren führen. Die erhöhte Sensitivität der Flarereaktion bei Fibromyalgiepatienten deutet auf eine veränderte Funktion der C-Faser Nozizeptoren hin.
    Notes: Summary C-fiber nociceptors not only serve afferent but also local efferent functions. The local efferent functions, such as vasodilatation, axon reflex flare reaction, plasma extravasation, and modulation of neuronal activity, are mediated via a local release of substance P, neurokinin A, and calcitonin gene-related peptide (CGRP) from the peripheral ending. CGRP is the main mediator of the capsaicin-induced flare reaction in the mammalian skin (including humans). In the pig skin the vasodilatation is due to activation of specific heat nociceptors. In the pigeon, antidromic vasodilatation is markedly inhibited by intrinsic galanin. Plasma extravasation in the pig skin blister base or using microdialysis can be evoked by histamine, but not by electrical stimulation or capsaicin. The neurogenic component of the histamine response (64%) appears to be mediated via NK2 receptors and can be modulated by CGRP. There is some evidence that the neuropeptides can also sensitize or stimulate nociceptors. Since in the fibromyalgia syndrome an increased sensitivity of the flare reaction has been observed, the hyperalgesia might be partly due to altered functions of C-fiber nociceptors.

    Notes: Abstract Axon reflex vasodilatation and neurogenic plasma extravasation are characteristic cutaneous vascular responses mediated by neuropeptides released from stimulated capsaicin-sensitive sensory nerve endings. Intracutaneous injections of local anaesthetics inhibit the axon-reflex flare elicited by chemical irritants in human skin. Results of earlier reports on the effects of local anaesthetics on neurogenic plasma extravasation are controversial. The aim of the present study, therefore, was to re-examine the effect of the local anaesthetic lidocaine on the neurogenic inflammatory response of rat skin. The effects of lidocaine on cutaneous inflammatory reactions were measured quantitatively by means of the Evans blue technique. Intracutaneous injection of lidocaine resulted in a dose-dependent inhibition of the neurogenic inflammation elicited by mustard oil and of the dye leakage response to compound 48/80 or histamine. It is suggested that the site of this inhibition is beyond the sensory nerve terminal, presumably at the level of the vascular endothelium.

    Notes: Abstract  Perineural application of capsaicin results in a selective and permanent reduction in the sensitivity to noxious chemical and heat stimuli and elimination of the neurogenic inflammatory response. The present quantitative immunohistochemical study has been undertaken to reveal the populations of cutaneous afferent nerves that are affected by perineural capsaicin treatment. Areas of intact and chemodenervated skin were determined with the aid of the vascular labelling technique. In sections taken from intact skin areas, staining with antibodies against protein gene product 9.5 revealed a rich epidermal innervation. Fibres immunoreactive for growth-associated protein 43 were also abundant; nerve fibres immunoreactive for substance P and calcitonin gene-related peptide were less numerous. Somatostatin- and RT97-immunoreactive fibres were seen only in the subepidermal layer. In sections taken from skin areas supplied by the sciatic nerve treated with capsaicin 3 days previously, the number of epidermal nerve fibres immunoreactive to protein gene product 9.5, growth-associated protein 43, substance P and calcitonin gene-related peptide was reduced by 90%, 95%, 97% and 66%, respectively. These changes persisted for at least 42 days. The findings reveal that the majority of epidermal axons are capsaicin-sensitive and comprise a chemically heterogeneous population. Reductions in cutaneous fibre populations following perineural capsaicin treatment may result from both the degeneration of sensory axons and the depletion of neuron-specific macromolecules. In addition, most cutaneous nociceptive axons may not use the major sensory neuropeptides substance P and calcitonin gene-related peptide as afferent neurotransmitters.
