A Critical Role for Hemolysins and Bacterial Lipoproteins in Staphylococcus aureus-Induced Activation of the Nlrp3 Inflammasome
Open accessAbstract
The mechanism by which bacterial pathogens activate caspase-1 via Nlrp3 remains poorly understood. In this study, we show that the ability of Staphylococcus aureus, a leading cause of infection in humans, to activate caspase-1 and induce IL-1β secretion resides in culture supernatants of growing bacteria. Caspase-1 activation induced by S. aureus required α-, β-, and γ-hemolysins and the host Nlrp3 inflammasome. Mechanistically, α- and β-hemolysins alone did not trigger caspase-1 activation, but they did so in the presence of bacterial lipoproteins released by S. aureus. Notably, caspase-1 activation induced by S. aureus supernatant was independent of the P2X7 receptor and the essential TLR adaptors MyD88 and TIR domain-containing adapter-inducing IFN-β, but was inhibited by extracellular K+. These results indicate that S. aureus hemolysins circumvent the requirement of ATP and the P2X7 receptor to induce caspase-1 activation via Nlrp3. Furthermore, these studies revealed that hemolysins promote in the presence of lipoproteins the activation of the Nlrp3 inflammasome.

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.
