The skin develops probably the densest and most complex innervation of all mammalian organs, consisting of sensory and autonomic nerves loaded with a plethora of neuropeptides and neurotransmitters. Skin innervation, as well as the expression patterns of neurotrophins and their receptors, is subject to dramatic changes during not only morphogenesis but also adult tissue remodeling under physiological or inflammatory conditions. Bilateral neuroimmune interactions are the basis of adaptive responses to tissue remodeling (such as hair cycling), psycho-emotional stress or skin inflammation. Dermatitis and hair loss may be exacerbated by stress-induced neurogenic inflammation. In addition, selected inflammatory skin diseases are associated with increased innervation. Finally, inflammatory cytokines influence the cutaneous expression of neurotrophins, as well as neurotrophin-induced neurite outgrowth following axotomy. Here, we review key studies on bilateral neuroimmune interactions in the skin under both healthy and disease conditions to provide a basis for future research on the role of inflammation in peripheral nerve regeneration.
