August 2005 in “Anatomy and Embryology” This study found that concentrated clusters of noradrenergic nerve fibers form a longitudinal linear system in rat skin, particularly innervating arrector pili muscles.
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.
In this study, rat vibrissa follicles transplanted into mice demonstrated survival, partial sympathetic nerve reinnervation, and increased norepinephrine levels 37 days post-implantation, suggesting potential for hair growth despite not returning to normal nerve function.
