In these conditions, persistent reactive gliosis can impede tissue repopulation and limit neurogenesis. Thus, modulating this phenomenon has been increasingly recognized as potential therapeutic approach. Methods: In this study, we investigated the potential of the flavonoid agathisflavone to modulate astroglial and microglial injury responses and promote neurogenesis in the subventricular zone (SVZ) neurogenic niche. Agathisflavone, or the vehicle in controls, was administered directly into the lateral ventricles in postnatal day (P)8-10 mice by twice daily intracerebroventricular (ICV) injections for 3 days, and brains were examined at P11. Results: In the controls, ICV injection caused glial reactivity along the needle track, characterised immunohistochemically by increased astrocyte expression of glial fibrillary protein (GFAP) and the number of Iba-1+ microglia at the lesion site. Treatment with agathisflavone decreased GFAP expression, reduced both astrocyte reactivity and the number of Iba-1+ microglia at the core of the lesion site and the penumbra, and induced a 2-fold increase on the ratio of anti-inflammatory CD206+ to pro-inflammatory CD16\/32+ microglia. Notably, agathisflavone increased the population of neuroblasts (GFAP+ type B cells) in all SVZ microdomains by up to double, without significantly increasing the number of neuronal progenitors (DCX+). Conclusions: Although future studies should investigate the underlying molecular mechanisms driving agathisflavone effects on microglial polarization and neurogenesis at different timepoints, these data indicate that agathisflavone could be a potential adjuvant treatment for TBI or central nervous system disorders that have reactive gliosis as a common feature.<\/jats:p>","DOI":"10.3390\/nu16234053","type":"journal-article","created":{"date-parts":[[2024,11,26]],"date-time":"2024-11-26T09:10:14Z","timestamp":1732612214000},"page":"4053","update-policy":"https:\/\/doi.org\/10.3390\/mdpi_crossmark_policy","source":"Crossref","is-referenced-by-count":3,"title":["Agathisflavone Modulates Reactive Gliosis After Trauma and Increases the Neuroblast Population at the Subventricular Zone"],"prefix":"10.3390","volume":"16","author":[{"ORCID":"https:\/\/orcid.org\/0000-0001-8403-6016","authenticated-orcid":false,"given":"Juliana Helena","family":"Castro e Silva","sequence":"first","affiliation":[{"name":"Laboratory of Neurochemistry and Cellular Biology, Department of Biofunction, Health Sciences Institute, Federal University of Bahia, Salvador 40231-300, Brazil"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-6052-6288","authenticated-orcid":false,"given":"Francesca","family":"Pieropan","sequence":"additional","affiliation":[{"name":"School of Medicine, Pharmacy and Biomedical Sciences, University of Portsmouth, Portsmouth PO1 2UP, UK"},{"name":"Southampton Solent University, E Park Terrace, Southampton SO14 0YN, UK"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Andrea Domenico","family":"Rivera","sequence":"additional","affiliation":[{"name":"School of Medicine, Pharmacy and Biomedical Sciences, University of Portsmouth, Portsmouth PO1 2UP, UK"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"ORCID":"https:\/\/orcid.org\/0000-0001-7579-0746","authenticated-orcid":false,"given":"Arthur Morgan","family":"Butt","sequence":"additional","affiliation":[{"name":"School of Medicine, Pharmacy and Biomedical Sciences, University of Portsmouth, Portsmouth PO1 2UP, UK"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-8975-3871","authenticated-orcid":false,"given":"Silvia Lima","family":"Costa","sequence":"additional","affiliation":[{"name":"Laboratory of Neurochemistry and Cellular Biology, Department of Biofunction, Health Sciences Institute, Federal University of Bahia, Salvador 40231-300, Brazil"}],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"1968","published-online":{"date-parts":[[2024,11,26]]},"reference":[{"key":"ref_1","doi-asserted-by":"crossref","first-page":"1","DOI":"10.3233\/JAD-191150","article-title":"Inflammation in traumatic brain injury","volume":"74","author":"Postolache","year":"2020","journal-title":"J.
