Hypothesis

Notch signaling may play a role in the pathogenesis of sepsis.

Conclusion

Notch inhibitors may be useful as adjunctive agents for treating sepsis syndrome.

Supporting Evidence

  • Notch signaling was activated after LPS stimulation.
  • Disruption of Notch signaling by DAPT reduced inflammatory responses.
  • DAPT treatment improved survival in experimental sepsis models.

Takeaway

This study shows that a signaling pathway called Notch helps control inflammation during sepsis, and blocking it can help improve survival in mice.

Methodology

The study used real-time PCR and western blotting to analyze Notch signaling in LPS-stimulated murine macrophages and tested the effects of a Notch inhibitor in vitro and in vivo.

Limitations

The protective effect of the Notch inhibitor DAPT was only partial in vivo.

Participant Demographics

Murine macrophage cell line and C56BL/6 strain mice were used.
