PITTSBURGH, PA – A collaborative research effort has yielded a potentially life-saving therapy for carbon monoxide (CO) poisoning, a pervasive threat to first responders and the public alike. Scientists at the University of Pittsburgh and the University of Maryland School of Medicine have engineered a novel treatment derived from a naturally occurring protein,offering a significantly faster response than current methods.
The Silent Threat of Carbon Monoxide
Carbon monoxide is a colorless, odorless gas that interferes with the blood’s ability to carry oxygen. Worldwide, tens of thousands succumb to CO poisoning annually, with millions more experiencing non-fatal incidents. The insidious nature of CO stems from its ability to bind to hemoglobin-the oxygen-carrying protein in red blood cells-with a far greater affinity than oxygen, leading to hypoxia and a range of symptoms from headaches and nausea to dizziness and ultimately, loss of consciousness.
Did You Know? Carbon monoxide poisoning is a leading cause of unintentional poisoning deaths in the United States, with approximately 430 deaths each year, according to the Centers for Disease Control and Prevention.
A Novel Approach: RcoM-HBD-CCC
the newly developed therapy centers around a hemoprotein called RcoM-HBD-CCC, sourced from the bacterium Paraburkholderia xenovorans. This protein functions as a “sponge,” actively scavenging carbon monoxide from the bloodstream. researchers detail their findings in a recent publication in the Proceedings of the National Academy of Sciences (DOI: 10.1073/pnas.2501389122).

speeding Up Response Times
Current treatments for CO poisoning primarily involve administering high-flow oxygen,sometimes in hyperbaric chambers for severe cases. While effective, these methods are time-consuming, a critical drawback in emergency situations where every minute counts. The “golden hour”-and even the “platinum ten minutes”-are crucial in trauma care, and conventional CO treatments can feel agonizingly slow.
In contrast, RcoM-HBD-CCC demonstrates remarkable speed. Studies indicate the protein can remove half of the carbon monoxide from the bloodstream in under a minute.Researchers discovered that RcoM-HBD-CCC binds to CO nearly 50 times faster than hemoglobin, initiating detoxification immediately upon entering the circulatory system.
Addressing a Key Challenge: Nitric Oxide Affinity
A significant hurdle in developing CO antidotes has been finding a substance that selectively targets carbon monoxide without interfering with nitric oxide. Nitric oxide is vital for regulating blood pressure, and disrupting its function could lead to risky hypertension. Fortunately, intravenous administration of RcoM-HBD-CCC in mice showed no hypertensive effects, a crucial finding for its potential clinical request.
pro tip: Regular maintenance of fuel-burning appliances, such as furnaces and water heaters, and the installation of carbon monoxide detectors are essential preventative measures against CO poisoning.
Looking Ahead: Clinical Trials and Beyond
Timothy johnstone, a guest editor for the research paper and a researcher at the University of California, Santa Cruz, expressed optimism about the therapy’s future. “This is a problem so uniquely suited to a bioinorganic solution,” Johnstone stated. “Technical improvements like the one described here will only continue to bring the application closer to practical realization.”
Beyond its potential as an antidote, RcoM-HBD-CCC’s unique properties could pave the way for advancements in oxygen delivery systems, treatments for anemia and blood loss, and even organ preservation techniques for transplantation.Researchers are now focused on scaling up production and preparing for human clinical trials.

Carbon Monoxide Poisoning: A Persistent Public health Concern
Carbon monoxide poisoning remains a significant public health issue, especially during colder months when heating systems are in use. Awareness of the risks, proper ventilation, and the use of CO detectors are crucial for prevention. The development of RcoM-HBD-CCC represents a major step forward in emergency medical care, offering a faster and more effective treatment option for a potentially deadly condition.
Frequently Asked Questions About Carbon Monoxide Poisoning and New Treatments
- What is carbon monoxide poisoning? Carbon monoxide poisoning occurs when CO gas builds up in your bloodstream, replacing oxygen and leading to hypoxia.
- What are the symptoms of CO poisoning? Symptoms range from headache, dizziness, and nausea to confusion, loss of consciousness, and ultimately, death.
- How is CO poisoning currently treated? Current treatment involves administering high-flow oxygen, sometimes in a hyperbaric chamber.
- How does rcom-HBD-CCC work? This protein acts as a “sponge,” rapidly scavenging carbon monoxide from the bloodstream.
- When will this new therapy be available? The therapy is currently in pre-clinical development and is expected to enter human clinical trials in 2026.
