Degradation of NETs as a risk factor for severe coinfections and damage of the lung. In the case of a severe lung infection, e.g., with SARS-CoV-2, neutrophils are activated and release NETs. The host itself produces nucleases to eliminate and recycle NET products. Importantly, nuclease-mediated degradation of NETs may promote the growth of certain bacteria that use degraded NET products as an efficient source for NAD or adenosine.
