Abstract:
The recognition of ferroptosis as a distinct, iron-dependent, yet caspase-independent form of cell death has captivated the cell death research field. This discovery has also rekindled optimism that antioxidant approaches, historically disappointing in clinical trials for stroke and related diseases, may yet achieve therapeutic relevance. However, despite an expanding body of literature, knowledge of ferroptosis has not yet translated into meaningful advances for neurological conditions in humans. Here, we summarize evidence supporting the hypothesis that intracerebral hemorrhage, as a prototypical iron-overload disorder, induces tissue damage and functional impairment through ferroptotic mechanisms. Specifically, erythrocyte lysis releases hemoglobin and its degradation product hemin, promoting lipid peroxidation and antioxidant collapse, culminating in neuronal ferroptosis. We further propose that endogenous homeostatic responses driven by pharmacological selenium supplementation, including a novel selenium-based peptide developed in our laboratory, represent effective strategies to mitigate injury and improve functional recovery in rodent models of hemorrhagic and ischemic stroke. Given reproducible effects across models and laboratories, we argue that anti-ferroptotic interventions, particularly those that limit the toxic effects of redox-active iron and reinforce GPX4-centered defenses, warrant advancement toward human clinical trials.
Insights
Ferroptosis, a cell death form, causes brain damage after hemorrhage. Selenium therapies show promise in mitigating this injury and improving recovery in stroke models, warranting clinical trials.
Area of Science:
- Neuroscience
- Cell Biology
- Biochemistry
Background:
- Ferroptosis is an iron-dependent, caspase-independent cell death pathway.
- Antioxidant therapies have shown limited success in clinical trials for neurological diseases.
- Translating ferroptosis knowledge into human neurological treatments remains a challenge.
Purpose of the Study:
- To investigate the role of ferroptosis in intracerebral hemorrhage-induced tissue damage.
- To explore selenium supplementation as a therapeutic strategy against ferroptosis in stroke models.
- To evaluate a novel selenium-based peptide for mitigating neurological injury.
Main Methods:
- Summarizing evidence linking intracerebral hemorrhage to ferroptotic mechanisms.
- Utilizing rodent models of hemorrhagic and ischemic stroke.
- Assessing the effects of pharmacological selenium supplementation and a novel selenium-based peptide.
Main Results:
- Intracerebral hemorrhage induces neuronal ferroptosis via iron overload, hemoglobin/hemin release, lipid peroxidation, and antioxidant collapse.
- Selenium supplementation and the novel peptide mitigated injury and improved functional recovery in stroke models.
- Effects were reproducible across different models and laboratories.
Conclusions:
- Ferroptosis plays a key role in the pathophysiology of intracerebral hemorrhage.
- Targeting ferroptosis, particularly redox-active iron and GPX4 defenses, offers a promising therapeutic avenue for stroke.
- Anti-ferroptotic interventions warrant advancement to human clinical trials for neurological conditions.

Cell death was observed in the early 19th century, but there was no experimental evidence to prove it. In 1842, Carl Vogt first discovered cell death in a metamorphic toad; however, it was not termed ‘cell death.’ Scientists discovered different cell death pathways only in the...
