New study reveals how LGALS3BP protein fuels liver damage in sepsis

New research highlights the role of LGALS3BP in worsening liver damage during sepsis. The protein acts as a molecular signal that intensifies inflammation in liver tissue. Scientists now see it as a potential target for reducing organ failure in severe infections. LGALS3BP functions as a danger-associated molecular pattern, or DAMP. It triggers a chain reaction in liver cells, activating the NLRP3 inflammasome and cleaving gasdermin D. This process leads to pyroptosis, a form of inflammatory cell death.

The protein also influences other inflammatory pathways. It activates NF-κB and boosts cytokine production, creating a more aggressive inflammatory environment. In septic patients, high levels of LGALS3BP correspond with abnormal liver enzymes and higher disease severity.

Experiments with LGALS3BP knockout mice showed promising results. These mice had less liver inflammation, weaker inflammasome responses, and better survival rates during sepsis. The findings suggest that blocking LGALS3BP could reduce tissue damage and improve outcomes. Targeting LGALS3BP may help control inflammasome activity and prevent pyroptosis in the liver. This approach could preserve liver function and lower mortality in sepsis. The study also broadens the understanding of inflammatory cell death in liver disease beyond traditional models.
