Abstract:
Sepsis is an infection-induced syndrome characterized by systemic immune dysregulation and has traditionally been treated primarily with antibiotics. Although antibiotics remain essential for pathogen control, they rarely reverse immune dysfunction, barrier disruption, or microbial ecological imbalance in sepsis, suggesting that a purely anti-infective paradigm may be insufficient. In such phenotypes, microbiome-centered approaches may complement conventional anti-infective strategies by supporting microbial ecological restoration, host immune recalibration and disease tolerance. There is increasing evidence that the microbiome plays an important role in sepsis pathogenesis and immune modulation, both as a byproduct of immune perturbation and as a context-dependent mediator of immune maladaptation. Such insights underpin therapeutic strategies that integrate immune reprogramming with ecological restoration beyond infection control. Recent progress in single-cell omics, spatial transcriptomics and metabolomics is starting to uncover the complex interactions between microbial communities and the host immune system, providing new conceptual and translational pathways. Precise microbiome modulation combined with targeted immune recalibration may help shape future sepsis therapy, centered on restoring immune-microbial homeostasis rather than simply suppressing inflammation.
Insights
Sepsis treatment needs more than antibiotics. Microbiome-centered strategies can restore immune balance and microbial ecology for better sepsis recovery.
Area of Science:
- Immunology
- Microbiology
- Genomics
Background:
- Sepsis is an infection-induced syndrome with systemic immune dysregulation.
- Antibiotics are standard but often fail to restore immune function or microbial balance.
- A purely anti-infective approach may be insufficient for comprehensive sepsis management.
Purpose of the Study:
- To explore microbiome-centered approaches as a complement to conventional sepsis therapy.
- To highlight the role of microbial ecological restoration and host immune recalibration.
- To investigate novel therapeutic strategies integrating immune reprogramming with ecological restoration.
Main Methods:
- Review of current evidence on microbiome's role in sepsis pathogenesis.
- Analysis of recent advancements in single-cell omics, spatial transcriptomics, and metabolomics.
- Conceptual framework for integrating microbiome modulation with immune recalibration.
Main Results:
- The microbiome significantly influences sepsis pathogenesis and immune modulation.
- Microbiome-centered approaches can support microbial ecological restoration and disease tolerance.
- Advanced omics technologies are revealing complex host-microbial interactions.
Conclusions:
- Future sepsis therapy should integrate microbiome modulation with immune recalibration.
- Restoring immune-microbial homeostasis is a promising therapeutic goal beyond simple inflammation suppression.
- Precision microbiome modulation offers new translational pathways for sepsis treatment.
