Laminaria japonica Polysaccharide Mitigates Acute Neuroinflammation in Cerebral Ischemia-Reperfusion Injury

Laminaria japonica polysaccharide (LJP) has been reported to exert anti-inflammatory and neuroprotective effects, but its molecular mechanisms in I/R injury remain unclear. In this study, we performed transcriptome sequencing on ischemic brain tissues from Sham, Vehicle, and LJP-treated mice to elucidate the molecular mechanisms underlying LJP’s anti-inflammatory actions.

Our results show that LJP treatment significantly modulated the expression of key genes involved in inflammatory responses, particularly through the regulation of Csf3-mediated pathways. These findings provide novel insights into the therapeutic potential of LJP for ischemic stroke and identify potential targets for future interventions.
