What this research studies

This project uses a pig model that mimics human carbon monoxide poisoning to learn how mitochondria in the brain are damaged and whether a succinate prodrug can help. Researchers will measure blood cells and use optical sensors to read the redox state of a brain enzyme (Complex IV) alongside standard measures like carboxyhemoglobin. By giving the mitochondrial-supporting drug with oxygen therapies, they will compare changes in mitochondrial function and the optical/blood signals to see which markers best reflect injury and recovery. The goal is to find better biomarkers and a potential antidote that could move into human trials.

Who could benefit from this research

Good fit: People with recent acute carbon monoxide exposure—for example from house fires or exhaust inhalation—who present to emergency care and are candidates for oxygen or hyperbaric therapy.

Not a fit: People with chronic low-level CO exposure, long-standing, irreversible brain injury, or conditions unrelated to CO poisoning are unlikely to benefit directly from this work.

Why it matters

Potential benefit: Could lead to faster, more accurate tests of injury and a new mitochondrial-based antidote that reduces brain damage after carbon monoxide exposure.

How similar studies have performed: Early animal data from the team show promise that a succinate prodrug can relieve partial Complex IV inhibition, but human benefit has not yet been demonstrated.
