Abstract

The adoption of Warburg metabolism is critical for the activation of macrophages in response to lipopolysaccharide. Macrophages stimulated with lipopolysaccharide increase their expression of nicotinamide phosphoribosyltransferase (NAMPT), a key enzyme in NAD+ salvage, and loss of NAMPT activity alters their inflammatory potential. However, the events that lead to the cells' becoming dependent on NAD+ salvage remain poorly defined. We found that depletion of NAD+ and increased expression of NAMPT occurred rapidly after inflammatory activation and coincided with DNA damage caused by reactive oxygen species (ROS). ROS produced by complex III of the mitochondrial electron-transport chain were required for macrophage activation. DNA damage was associated with activation of poly(ADP-ribose) polymerase, which led to consumption of NAD+. In this setting, increased NAMPT expression allowed the maintenance of NAD+ pools sufficient for glyceraldehyde-3-phosphate dehydrogenase activity and Warburg metabolism. Our findings provide an integrated explanation for the dependence of inflammatory macrophages on the NAD+ salvage pathway.

  • NAD+ turnover during the first few hours of M1 macrophage polarization depends on reactive oxygen species-induced DNA damage and PARP1 activation.

    “This study and another recent report6,102 suggest that this NAD+ turnover, particularly during the first few hours of macrophage M1 polarization, depends on reactive oxygen species-induced DNA damage and activation of PARP1.”
  • M1 macrophages are protected from reactive oxygen species-induced DNA damage as a result of increased transcription of antioxidant defence genes such as SOD2.

    “M1 macrophages are protected from reactive oxygen species-induced DNA damage as a result of increased transcription of genes involved in antioxidant defence, such as SOD2 (REFS102–104).”
  • M1 macrophage polarization is associated with enhanced NAD+ degradation, and inhibiting NAMPT blocks glycolytic shifts in M1 macrophages, limiting proinflammatory responses in vitro and reducing systemic inflammation in vivo in response to sepsis.

    “a recent study found that M1 macrophage polarization is associated with enhanced degradation of NAD+ and that inhibiting NAMPT blocks glycolytic shifts in M1 macrophages, limiting proinflammatory responses in vitro and reducing systemic inflammation in vivo in response to sepsis102.”

About these checks

Registry, retraction, Cites and statistics results are computed, not judged, with one exception: a printed reference that no index lists is read once by a model before it counts as a citation error. Claims are extracted by a model and kept only when their quote appears verbatim in the text; each cited source is then checked, with a model’s help, for whether it says what the claim relies on. Those verdicts can be wrong — read the claim’s quote and the cited source before relying on one.

Statistics and arithmetic are recomputed, not judged.

Confidence bands are shown only for fields calibrated on our annotated test set. None is calibrated yet, so no band is shown.
