In the case of Lpn-GFP infection this indicates that there were more NOX2-deficient neutrophils that contained dead or viable L. pneumophila than WT neutrophils, and in the case of Lpn-GFPind infection it indicates that there were more NOX2-deficient neutrophils that contained viable L. pneumophila than WT neutrophils in the same mouse. Here, CYBB is linked to infection.
