Document: The copyright holder for this preprint (which was not peer-reviewed) is the . https://doi.org/10.1101/632372 doi: bioRxiv preprint exacerbators at stable state and during virus positive exacerbation. The potential importance of MBL-2 during virus-associated exacerbation was further demonstrated by our finding that its expression correlated negatively with bacterial loads during exacerbation. MBL is a key component of innate immunity that activates the lectin complement pathway and is involved in the process of bacterial phagocytosis 31 . MBL deficiency is associated with susceptibility to respiratory tract infections and pneumonia in healthy individuals 32, 33 and to increased risk of sepsis in animal models 34 . MBL can bind to various pathogens of relevance to COPD exacerbations including both viruses and bacteria 35 .
