Abstract:
Skin wound repair is critically regulated by peripheral nerves. Injury or dysfunction of these nerves represents a key factor impairing the healing of pathological wounds, such as diabetic ulcers and deep burns. The mechanisms by which peripheral nerves participate in cutaneous wound healing primarily involve modulation of immune responses, construction of stem cell niches, and promotion of angiogenesis. Sensory neurons initiate and mediate essential local immune responses, contribute to the epidermal stem cell microenvironment, and support regenerative potential. Sympathetic nerves bidirectionally regulate immune homeostasis via the release of various neuromodulators and precisely control the activation of hair follicle stem cells as well as the homeostasis of melanocyte stem cells. Schwann cells also play pivotal roles in immune modulation, balancing repair processes and mitigating scar formation. During revascularization, sensory and autonomic nerve terminals release neurotransmitters that precisely regulate vasomotor activity and angiogenesis, while Schwann cells facilitate the reconstruction of functional vascular networks via potent paracrine signaling. This review systematically summarizes the crucial roles of peripheral nerves in skin wound repair, with emphasis on their regulatory mechanisms in immune responses, stem cell activation and homeostasis, and vascular dynamics, thereby providing insights into the development of novel therapeutic strategies targeting peripheral nerve regulation.
