Stroke is the main cause of death and functional disability. The available therapy affects only 5% of patients, and new therapeutic approaches have been constantly tested. Transcranial photobiomodulation (PBM) is promising for its neuroprotective effect on brain injuries. Thus, the present study investigated the PBM effects in an in vivo model of ischemic stroke induced by photothrombosis (PT). Five different groups of Wistar rats were submitted or not to a daily dose of fish oil or/and laser sessions for 2 months. The ischemia volume was evaluated by stereology; GFAP, Iba and NeuN by immunohistochemistry; TNF‐α, IL‐1β, IL‐6, IL‐10 and TGF‐β by ELISA assay. PBM influenced both the lesion volume and the GFAP. Furthermore, PBM and Ω‐3 or both reduced Iba RNAm. PBM reduced TNF‐α, IL‐1β, IL‐6, brain damage, neuroinflammation and microglial activation, and it increased astroglial activity in peri‐lesioned region after stroke. [ABSTRACT FROM AUTHOR] |
