摘要: Background Depressive behavior in animals is often associated with reduced levels of brain-derived neurotrophic factor (BDNF) and impaired neurogenesis the hippocampus. Recent studies showed that T cells recognizing central nervous system (CNS)-specific antigens can regulate adult hippocampal expression BDNF. On basis these findings, we hypothesized controlling CNS specific immune activity by immunization a myelin-related peptide may have an antidepressant effect. Methods We investigated impact related peptide, on behavioral cellular outcomes chronic mild stress (CMS; animal model for depression) rats. Results Immunization weak agonist myelin-derived ameliorated depressive such as anhedonia (measured sucrose preference), induced CMS The outcome was accompanied restoration BDNF neurogenesis. Conclusions results this study introduce novel approach CNS-related therapeutic means fighting depression. Vaccination, therapy, invoke several molecular pathways are known to be regulated drugs. Therefore, suggest immune-based therapies should considered treatment
