HSP60 Mediates NLRP3 Inflammasome-Dependent Microglial Pyroptosis Via the TLR4/MyD88/NF-κB Signaling Axis After Subarachnoid Hemorrhage.

ABSTRACT: This study aims to elucidate the mechanism by which Heat Shock Protein 60 (HSP60) mediates microglial pyroptosis in the context of early brain injury (EBI) following subarachnoid hemorrhage (SAH), and to investigate the effects of HSP60 inhibition on EBI after SAH. A mouse subarachnoid hemorrhage (SAH) model was established using prechiasmatic cistern blood injection. In vitro, microglia were stimulated with 25 µmol/L oxyhemoglobin (OxyHB) to simulate the SAH pathological environment. In vivo, mice received 100 mg/kg Mizoribine, while in vitro, 80 µmol/L Mizoribine was used to suppress SAH-induced HSP60 upregulation. Techniques including Western blotting, immunofluorescence, immunohistochemistry, transmission electron microscopy, ELISA, modified Garcia neurological scoring, beam walking, b
