The association between BDNF and major depressive disorder is the subject of extensive research. Indeed, numerous studies indicate that decreased levels of BDNF are linked to an increased occurrence of depressive symptoms, neuronal loss, and cortical atrophy. Moreover, it has been observed that antidepressive therapy can help restore BDNF levels. In this review, we will focus on the role of BDNF in major depression disorder serotonergic imbalance and associated stress conditions, particularly hypothalamic\u2013pituitary\u2013adrenal (HPA) axis dysregulation and oxidative stress. All of these features are highly connected to BDNF signaling pathways in the context of this disease, and exploring this topic will aim to advance our understanding of the disorder, improve diagnostic and treatment approaches, and potentially identify new therapeutic targets to alleviate the heavy burden of depression on society.<\/jats:p>","DOI":"10.3390\/pharmaceutics15082081","type":"journal-article","created":{"date-parts":[[2023,8,3]],"date-time":"2023-08-03T11:13:06Z","timestamp":1691061186000},"page":"2081","update-policy":"https:\/\/doi.org\/10.3390\/mdpi_crossmark_policy","source":"Crossref","is-referenced-by-count":122,"title":["BDNF Unveiled: Exploring Its Role in Major Depression Disorder Serotonergic Imbalance and Associated Stress Conditions"],"prefix":"10.3390","volume":"15","author":[{"ORCID":"https:\/\/orcid.org\/0000-0002-8231-1560","authenticated-orcid":false,"given":"Ana Salom\u00e9","family":"Correia","sequence":"first","affiliation":[{"name":"OncoPharma Research Group, Center for Health Technology and Services Research (CINTESIS), Rua Doutor Pl\u00e1cido da Costa, 4200-450 Porto, Portugal"},{"name":"CINTESIS@RISE, Faculty of Medicine, University of Porto, Alameda Professor Hern\u00e2ni Monteiro, 4200-319 Porto, Portugal"},{"name":"Institute of Biomedical Sciences Abel Salazar (ICBAS), University of Porto, Rua de Jorge Viterbo Ferreira, 228, 4050-313 Porto, Portugal"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-2967-6990","authenticated-orcid":false,"given":"Armando","family":"Cardoso","sequence":"additional","affiliation":[{"name":"CINTESIS@RISE, Faculty of Medicine, University of Porto, Alameda Professor Hern\u00e2ni Monteiro, 4200-319 Porto, Portugal"},{"name":"NeuroGen Research Group, Center for Health Technology and Services Research (CINTESIS), Rua Doutor Pl\u00e1cido da Costa, 4200-450 Porto, Portugal"},{"name":"Unit of Anatomy, Department of Biomedicine, Faculty of Medicine, University of Porto, Alameda Professor Hern\u00e2ni Monteiro, 4200-319 Porto, Portugal"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-1283-1042","authenticated-orcid":false,"given":"Nuno","family":"Vale","sequence":"additional","affiliation":[{"name":"OncoPharma Research Group, Center for Health Technology and Services Research (CINTESIS), Rua Doutor Pl\u00e1cido da Costa, 4200-450 Porto, Portugal"},{"name":"CINTESIS@RISE, Faculty of Medicine, University of Porto, Alameda Professor Hern\u00e2ni Monteiro, 4200-319 Porto, Portugal"},{"name":"Department of Community Medicine, Information and Health Decision Sciences (MEDCIDS), Faculty of Medicine, University of Porto, Alameda Professor Hern\u00e2ni Monteiro, 4200-319 Porto, Portugal"}],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"1968","published-online":{"date-parts":[[2023,8,3]]},"reference":[{"key":"ref_1","doi-asserted-by":"crossref","first-page":"917527","DOI":"10.3389\/fneur.2022.917527","article-title":"A Brief Overview on BDNF-Trk Pathway in the Nervous System: A Potential Biomarker or Possible Target in Treatment of Multiple Sclerosis?","volume":"13","author":"Iacono","year":"2022","journal-title":"Front.
