Innate immunity and immunotherapy for hemorrhagic shock

Area of Science:

• Immunology
• Trauma Medicine
• Critical Care

Background:

• Hemorrhagic shock (HS) involves hypovolemic injury where the innate immune response is central to organ damage.
• Early and exaggerated innate immune activation in HS causes systemic inflammation, cytokine storms, and complement activation.

Purpose of the Study:

• To review the innate immune response in HS injury.
• To detail recent therapeutic strategies for innate immune regulation in HS.
• To assess the clinical translation potential of these immune-based therapies.

Main Methods:

• Review of preclinical and clinical studies on innate immune regulation in HS.
• Systematic detailing of therapeutic strategies including stem cells, exosomes, genetic approaches, and others.
• Assessment of clinical studies and translation potential.

Main Results:

• Innate immunity plays a critical role in HS pathophysiology and organ injury.
• Numerous therapeutic strategies targeting innate immune regulation have emerged.
• Clinical studies show potential for immune regulation in HS treatment.

Conclusions:

• Understanding the innate immune response to HS is crucial for developing targeted therapies.
• Immune-modulating strategies offer promising avenues to mitigate HS-induced organ dysfunction and mortality.
• Further translation of basic research to clinical practice is needed to improve HS patient outcomes.
