Nanoparticle-based approaches for sepsis treatment: Current trends and perspectives

Area of Science:

• Biomedical Engineering
• Immunology
• Pharmacology

Background:

• Sepsis is a life-threatening organ dysfunction due to an unbalanced host response to infection.
• Current sepsis management focuses on infection control and homeostasis, with limited immunomodulatory options like corticosteroids.
• Nanoparticles show potential for targeted delivery and intervention in sepsis pathology.

Purpose of the Study:

• To review current knowledge on nanoparticle-based therapies for sepsis.
• To explore how nanomaterials can address complex multicellular pathways in sepsis.
• To cover a range of interventions from antimicrobial to immunomodulatory strategies.

Main Methods:

• Review of recent studies on nanoparticle applications in sepsis.
• Analysis of strategies targeting inflammation and immunosuppression.
• Discussion of antibacterial, cleansing, and cell-specific modulation techniques.

Main Results:

• Nanoparticles can be developed for antimicrobial effects and to manage sepsis-induced inflammation.
• Nanomaterials can target both hyperinflammatory and immunosuppressive phases of sepsis.
• Emerging RNA-loaded nanoparticles represent a novel therapeutic approach for sepsis.

Conclusions:

• Nanoparticle-based therapies present a versatile platform for addressing multifaceted sepsis pathology.
• Targeted delivery by nanoparticles can modulate key mechanisms in sepsis, including immune dysregulation.
• Future research directions include nucleic acid-based nanoparticle therapies for improved sepsis treatment.
