Abstract

Subarachnoid hemorrhage (SAH), a stroke subtype associated with high mortality, is closely linked to neuroinflammation. Phloretin, a naturally occurring flavonoid abundant in fruits, possesses anti-inflammatory properties. However, its specific role in SAH remains unclear. Therefore, we aimed to investigate the potential role of phloretin in SAH. We established in vitro and in vivo SAH models to assess the effects of phloretin. Subsequently, utilizing SAH-related public datasets from the GEO database, we identified key genes associated with SAH and investigated the potential mechanism of action of phloretin. Our findings reveal that phloretin significantly improves prognostic outcomes and mitigates inflammation in SAH mice. Moreover, our results suggest that phloretin mitigates neuroinflammation by inhibiting the TLR2/MyD88/NF-κB pathway.
