Experimental design. Photobiomodulation (PBM) was administered daily, for 30 min per day, on days 1 through 5 and days 8 through 12. On day 11, mice received either LPS (1 mg/kg) or vehicle injection, IP, 30 min after PBM. On day 12, mice received a final PBM treatment before tissue was collected at 24 hrs after LPS. Luminex, qPCR and western blot assays were performed on brain and plasma samples.
