June 2025 in “Stem Cell Research & Therapy” In this study, researchers found that isoproterenol, an adrenergic β2 receptor agonist, promoted hair growth and hair follicle stem cell proliferation in models of androgenetic alopecia by modulating the PI3K/AKT/β-Catenin pathway, suggesting a potential new therapeutic strategy for hair loss.

January 2016 in “Cells tissues organs” This study found that chemical sympathectomy inhibited hair follicle growth in mice, suggesting that sympathetic nerves may regulate keratinocyte behavior to promote hair growth.
December 2025 in “Frontiers in Immunology” This review highlights that disturbances in neuroimmune communication, particularly between sympathetic nerves and macrophages, may contribute to autoimmune diseases like rheumatoid arthritis and type 1 diabetes, and suggests potential therapeutic avenues by restoring this communication in preclinical and early clinical studies.

January 2020 in “Nature” This study found that stress-induced signaling from the sympathetic nervous system in mice led to the depletion of stem cells in hair follicles, resulting in premature greying.
May 2026 in “Nature Communications” In this study, researchers identified that keloid fibroblasts respond to neurotransmitters from catecholaminergic nerves by producing bone matrix proteins, mediated by β1-adrenergic receptor activation, leading to fibro-osseous reprogramming; blocking this signaling in a rodent model prevented the development of keloid-like pathology.
