To explore the role of damage-associated molecular patterns (DAMPs) in hepatic ischemia-reperfusion injury (HIRI) and their potential as biomarkers and therapeutic targets, emphasizing their significance in clinical outcomes.
Key Findings:
DAMPs are critical mediators of sterile inflammation in HIRI and have translational relevance beyond being inflammatory triggers.
DAMPs can be classified based on their cellular sources and the timing of their release during ischemia and reperfusion.
Circulating DAMP signatures may serve as minimally invasive tools for predicting early allograft dysfunction and assessing donor graft quality.
DAMP-driven sensing activates various immune responses that contribute to liver injury and impaired recovery.
Interpretation:
A DAMP-centered framework may connect molecular injury biology with biomarker-guided decision-making in liver transplantation and hepatic surgery, impacting clinical practice significantly.
Limitations:
Assay heterogeneity complicates the standardization of DAMP measurements.
Undefined sampling windows limit the effectiveness of DAMPs as biomarkers.
Insufficient multicenter validation hampers the clinical applicability of DAMP-related findings.
Distinguishing between reparative and pathogenic DAMP signaling remains a challenge.
Conclusion:
Understanding the spatiotemporal dynamics of DAMPs can enhance the clinical management of hepatic ischemia-reperfusion injury, ultimately improving patient outcomes.
