Effects of aging on human skin innervation.
To understand the effect of aging on human skin innervation, we investigated intraepidermal nerve fiber (IENF) density of skin biopsies. IENF densities of the distal leg were lower in elderly (> or = 60 years of age) than in young adults (19-39 years of age; 7.80 +/- 0.79 vs 13.55 +/- 0.85 fibers/mm, p < 0.01). A similar trend was also observed in the distal forearm (11.67 +/- 1.55 vs 19.39 +/-...
متن کاملInnervation of melanocytes in human skin
Communication between the nervous system and epidermal melanocytes has been suspected on the basis of their common embryologic origin and apparent parallel involvement in several disease processes, but never proven. In this study, confocal microscopic analysis of human skin sections stained with antibodies specific for melanocytes and nerve fibers showed intraepidermal nerve endings in contact ...
متن کاملInnervation territories of single sympathetic C fibers in human skin.
Microneurography techniques were used to record action potentials from unmyelinated nerve fibers (C fibers) in the cutaneous fascicles of the peroneal nerve in healthy volunteers. C units were identified by their long latency responses to electrical stimulation of their terminals in the skin. Their responsiveness to mechanical or heat stimuli applied to the skin or to sympathetic reflex provoca...
متن کاملInnervation territories of mechano-insensitive C nociceptors in human skin.
Microneurographic recordings were obtained in the peroneal nerve from 20 mechano-insensitive units (CMi) and six mechano-heat responsive C units (CMH) in healthy human subjects. Their innervation territories in the skin of the leg or foot were assessed by transcutaneous electrical stimulation with a pointed probe at intensities of 10 to 100 mA (0.2 ms) and, when applicable, by mechanical von Fr...
متن کاملModulation of keratinocyte proliferation by skin innervation.
Several lines of evidence suggest that sensory nerves ending at the skin have profound influences on their target, the epidermis. To test the hypothesis, we examined the consequences of denervation on the paw skin of rats by eliminating its innervation. We investigated temporal changes of nerve degeneration, keratinocyte proliferation and differentiation, gene expression, and epidermal thicknes...
