This study investigated the role of brain-derived neurotrophic factor (BDNF) in patients with degenerative lumbar stenosis, focusing on its expression and correlation with pain intensity. The study examined 96 patients with lumbar stenosis and 85 control participants. BDNF levels in the yellow ligamentum flavum were measured using reverse transcription quantitative polymerase chain reaction (RT-qPCR), enzyme-linked immunosorbent assay (ELISA), and western blot analysis. ⋯ These findings suggest that BDNF could serve as a biomarker for pain severity in degenerative lumbar stenosis at the protein level, although this was not consistently observed at the mRNA level; this highlights the potential for BDNF-targeted therapies in managing pain. Future research should involve larger longitudinal studies to validate these findings and explore therapeutic interventions. This study underscores the importance of considering molecular and lifestyle factors in the treatment of degenerative lumbar stenosis, aiming to improve patient outcomes through comprehensive, targeted approaches.
