Preclinical trial reveals how beta-glucan, a compound found in all fungi, can ‘reprogram’ immune cells to combat lung inflammation.

A recent study suggests that a common fungal component may help protect against flu-related lung damage.

Led by Professor Maziar Divangahi from McGill’s Faculty of Medicine and Health Sciences and the Research Institute of the McGill University Health Centre, the research team found that beta-glucan, when given to mice before influenza exposure, reduced lung damage, improved lung function, and lowered the risk of severe illness and death.
