Background And Objective:
The scavenger receptor class A (SRA), expressed in astrocytes, plays a critical role in hematoma clearance following intracerebral hemorrhage (ICH). This study employed a three-phase approach-cellular, animal, and clinical-to investigate how the Nrf2-SRA signaling axis modulates astrocyte phenotype and promotes hematoma resolution, with emphasis on its potential clinical relevance.
Methods:
RESULTS: CONCLUSION: Nrf2 enhances hematoma clearance after ICH by modulating astrocyte phenotype through upregulation of SRA within brain tissue. This regulatory effect appears tissue-specific, with minimal impact on circulating SRA levels. These findings highlight the Nrf2-SRA axis in the brain as a potential therapeutic target for promoting glial-mediated hematoma resolution.
