Astragaloside IV attenuates cerebral ischemia-reperfusion injury by suppressing PERK/eIF2α/ATF4-mediated endoplasmic reticulum stress through activation of the SHH signaling pathway.
BACKGROUND Cerebral ischemia-reperfusion injury (CIRI) triggers endoplasmic reticulum stress (ERS), a key pathological driver of neuronal apoptosis and neurological impairment. While the neuroprotective effects of astragaloside IV (AS-IV) are well-documented, the precise regulatory bridge between the Sonic Hedgehog (SH...
