Proteomic profiling and pathway analyses reveal molecular signatures and immune networks in pediatric sepsis

Key Points

The aim is to investigate immune and inflammatory pathways in pediatric sepsis to identify molecular signatures and network interactions.
Conducted proteomic profiling of immune responses in critically ill children with sepsis.
Analyzed cytokine signaling, particularly IL-10, as a key player in immune regulation.
Examined associations between immune pathways and clinical variables related to infection types.
Identified IL-10 signaling as a central component modulating hyperinflammation and immunosuppression.
Discovered distinct immune network activation patterns linked to various pathogen types and sources.
Proposed potential therapeutic targets based on immune response profiles for patient stratification.

Abstract

Pediatric sepsis is characterized by dysregulation of multiple immune and inflammatory pathways rather than isolated protein abnormalities. IL-10 and related cytokine signaling emerged as central nodes, providing insights into the balance between hyperinflammation and immunosuppression in critically ill children. Associations between pathways and clinical variables suggest that specific pathogen types and infection sources trigger distinct patterns of biological network activation, offering potential targets for patient stratification and pathway-directed therapeutics.
