Updated publication reference for PubMed record(s): 30985291. Abstract S. aureus is a major opportunistic pathogen infecting patients with diabetes. Increased mortality was observed following IV S. aureus infection in diabetic mice compared to non-diabetic controls, correlating with increased numbers of low density neutrophils (LDNs) and neutrophil extracellular traps (NETs). LDN development is dependent on TGF?, which was more activated in the diabetic host. Neutralization of TGF?, or the integrin responsible for its activation ?5?8, reduced numbers of LDNs and improved survival. Comparison of high and low density neutrophils identified PTEN signaling as a central regulator of LDN NET release. Inhibition of PTEN improved survival and decreased NET production in infected diabetic mice. MEDI4893*, a monoclonal antibody that neutralizes alpha toxin (AT) in development for prevention of S. aureus infection, was able to block TGF? activation, reduce LDNs and NETs, and significantly improve survival. Our data identify a population of neutrophils in infected diabetic mice which correlated with decreased survival and increased NET production. Targeting a single virulence factor of S. aureus prevented emergence of the LDN population and improved survival, supporting potential use of pathogen specific antibodies for treating diabetic infections.
