Beta-Glucan: A Potential Key to Flu Protection
A recent Canadian study suggests that a component found in fungi, known as beta-glucan, may offer protection against flu-related lung damage. This discovery highlights the potential of beta-glucan as a therapeutic agent for influenza.
The preclinical trial revealed that beta-glucan, present in mushrooms, yeast, oats, and barley, can “reprogram” immune cells, preventing lung inflammation. this reprogramming could be crucial in mitigating the severity of flu infections.
Research Findings: Beta-Glucan and disease Tolerance
Scientists at the Research Institute of the McGill University Health center conducted a study demonstrating that administering beta-glucan to mice before influenza exposure reduced lung damage, improved lung function, and lowered the risk of illness and death. Professor Maziar Divangahi led the team, discovering that a unique structure of this component can boost defenses against pathogens.
The study explored the concept of “disease tolerance,” focusing on regulating the body’s immunity to infection rather than directly targeting the virus. The findings indicated that beta-glucan significantly enhanced flu survival rates by modulating immune responses and preventing severe lung inflammation, a common cause of fatality.
The results, published in Nature Immunology, suggest that beta-glucan is a promising therapy for influenza and other emerging viral pathogens.
How Beta-Glucan Reprograms Immune Cells
According to researchers, beta-glucan has the remarkable ability to reprogram immune cells.
Nargis Khan, who conducted this research at McGill and is now an Assistant Professor at the University of Calgary, stated, “It is indeed remarkable how beta-glucan can reprogram certain immune cells, such as neutrophils, to control excessive inflammation in the lung.”
Kim Tran, co-first author who recently completed her Ph.D. at McGill, added, “neutrophils are traditionally known for causing inflammation, but beta-glucan has the ability to shift their role to reduce it.”
Rebalancing the Immune System: A Key to Flu Survival
Researchers emphasize that most flu-related deaths result from an overreaction of the immune system, rather than the virus itself.This highlights the importance of understanding how the immune system becomes imbalanced.
Divangahi explained, “Beta-glucan is found in the cell walls of all fungi, including some that live in and on our bodies as part of the human microbiome.” He further hypothesized, “It is indeed tempting to hypothesize that the levels and composition of fungi in an individual could influence how their immune system responds to infections, in part as of beta-glucan.”
With the ongoing flu season and the threat of bird flu (H5N1), the development of effective therapeutic strategies for respiratory diseases is crucial.
Future Research and Implications
The research was funded by the canadian Institutes of Health Research. Future studies will explore how these findings apply to humans, potentially paving the way for new treatments and preventative measures against influenza and other viral infections.
Beta-Glucan and Neutrophil Reprogramming
Research indicates that beta-glucan pretreatment before influenza A virus challenge can increase survival by inducing long-term reprogramming of neutrophils, promoting disease tolerance. The enhanced survival results from increased recruitment of neutrophils via RoRγt + T cells in the lung tissue. Beta-glucan treatment promotes granulopoiesis in a type 1 interferon-dependent manner,leading to the generation of a unique subset of immature neutrophils utilizing a mitochondrial oxidative metabolism and producing interleukin-10. Collectively, data indicate that beta-glucan reprograms neutrophils to promote disease tolerance against influenza.

Beta-Glucan and Flu Protection: Your Questions Answered
Published: March 9, 2025
This article addresses common questions about beta-glucan’s potential role in fighting flu infections, based on recent research.
What is Beta-Glucan?
Beta-glucans are a group of polysaccharides (complex sugars) found in the cell walls of fungi (like mushrooms), yeast, oats, and barley. They are known for their potential immune-modulating properties.

How Might Beta-Glucan Protect Against the Flu?
A recent Canadian study suggests that beta-glucan can offer protection against flu-related lung damage. The preclinical trial revealed that beta-glucan can reprogram immune cells, preventing lung inflammation, potentially mitigating the severity of the flu infections
How does beta-Glucan “Reprogram” Immune Cells?
Beta-glucan can reprogram immune cells, especially neutrophils, to control excessive inflammation in the lungs. Traditionally, neutrophils can cause inflammation. However beta-glucan shifts the role of the neutrophils to reduce inflammation.
What is “Disease Tolerance” and How Does Beta-Glucan Relate to It?
“Disease tolerance” refers to the body’s ability to limit the harm caused by an infection without necessarily eliminating the pathogen itself. The McGill University study found that beta-glucan enhances disease tolerance by modulating immune responses and preventing severe lung inflammation, a leading cause of death in flu cases. Instead of directly attacking the flu virus, beta-glucan helps to regulate the immune system’s response, preventing a dangerous overreaction.
Where is Beta-Glucan Found?
Beta-glucan is found in:
mushrooms
Yeast
Oats
Barley
Beta-glucan is also found in cell walls of all fungi,including some that live in and on our bodies as part of the human microbiome.
How Effective is Beta-Glucan?

What Does the Research Show About Beta-Glucan and Flu Survival Rates?
The study showed that administering beta-glucan to mice before influenza exposure reduced lung damage, improved lung function, and lowered the risk of illness and death, significantly enhancing flu survival rates.
Why Is Reducing Inflammation Crucial in Flu Infections?
Many flu-related deaths result from an overreaction of the immune system, causing excessive inflammation in the lungs, rather than the virus itself. beta-glucan helps to rebalance the immune system and prevent this harmful overreaction.
What Type of Immune Cells Does Beta-Glucan Affect?
Beta-glucan has notable affects on Neutrophils. Beta-glucan reprograms neutrophils to promote disease tolerance against influenza. Enhanced survival results from increased recruitment of neutrophils via RoRγt + T cells in the lung tissue.
What are the Next Steps in beta-Glucan Research?
Future studies will explore how these findings apply to humans, potentially paving the way for new treatments and preventative measures against influenza and other viral infections.
