Intracerebral hemorrhage (ICH) causes high mortality and morbidity, but our
knowledge of post-ICH neuronal death and related mechanisms is limited. In this
study, we first demonstrated that ferroptosis, a newly identified form of cell
death, occurs in the collagenase-induced ICH model in mice. We found that
administration of ferrostatin-1, a specific inhibitor of ferroptosis, prevented
neuronal death and reduced iron deposition induced by hemoglobin in organotypic
hippocampal slice cultures (OHSCs). Mice treated with ferrostatin-1 after ICH
exhibited marked brain protection and improved neurologic function. Additionally,
we found that ferrostatin-1 reduced lipid reactive oxygen species production and
attenuated the increased expression level of PTGS2 and its gene product
cyclooxygenase-2 ex vivo and in vivo. Moreover, ferrostatin-1 in combination with
other inhibitors that target different forms of cell death prevented
hemoglobin-induced cell death in OHSCs and human induced pluripotent stem
cell-derived neurons better than any inhibitor alone. These results indicate that
ferroptosis contributes to neuronal death after ICH, that administration of
ferrostatin-1 protects hemorrhagic brain, and that cyclooxygenase-2 could be a
biomarker of ferroptosis. The insights gained from this study will advance our
knowledge of the post-ICH cell death cascade and be essential for future
preclinical studies.
