A protein antidote and sensor for carbon monoxide exposure

Optimization of a carbon monoxide (CO) sensing hemoprotein for applications as an antidote for CO poisoning and a biosensor for CO detection in living cells

NIH-funded research Wayne State University · NIH-11137058

This project will build a protein that soaks up carbon monoxide and can act as an antidote or a detector to help people exposed to CO.

What this research studies

If you or someone else breathes dangerous carbon monoxide, researchers are working on a protein-based agent that can bind and remove CO from the blood. They are starting with a bacterial CO-sensing protein that binds CO much more tightly than hemoglobin, and will use lab tests to find the smallest working piece and the key building blocks that give it strong CO binding and stability. The best protein variants will then be tested for safety and effectiveness in preclinical models as steps toward an intravenously delivered antidote and a cellular CO sensor. The goal is to move promising candidates toward future human testing and real-world use.

Who could benefit from this research

Good fit: People who have experienced moderate to severe acute carbon monoxide exposure and need urgent removal of CO from their blood would be the eventual candidates for this approach.

Not a fit: People with chronic low-level CO exposure, conditions unrelated to CO poisoning, or those already fully recovered may not benefit from this intervention.

Why it matters

Potential benefit: If successful, this could become a fast, field-deployable antidote that reduces deaths and long-term heart or brain injury from CO poisoning and also provide tools to detect CO inside cells.

How similar studies have performed: This approach is novel: there is no existing clinical antidote that irreversibly scavenges CO, though the project builds on a recent discovery of a bacterial CO-binding protein with very high affinity.
