Dynamic Changes of Extracellular Matrix in Sepsis: A Review

Area of Science:

• Biomedical Science
• Pathophysiology
• Molecular Biology

Background:

• Extracellular matrix (ECM) is crucial for tissue structure and cell signaling.
• Sepsis involves systemic inflammation and oxidative stress, leading to ECM degradation.
• ECM fragments act as signaling molecules, influencing cellular processes.

Purpose of the Study:

• To synthesize current knowledge on ECM dynamics in sepsis pathogenesis.
• To elucidate the role of ECM impairment in sepsis progression.
• To understand ECM's impact on cellular signaling and tissue remodeling during sepsis.

Main Methods:

• Systematic review of current literature on ECM in sepsis.
• Analysis of ECM component degradation and remodeling in sepsis models.
• Investigation of signaling pathways activated by ECM fragments.

Main Results:

• ECM impairment is a critical hallmark of sepsis pathogenesis.
• Degraded ECM fragments activate signaling cascades regulating cell survival, proliferation, migration, and inflammation.
• ECM remodeling influences vascular function, immune response, and coagulation.
• Dysregulated ECM remodeling can lead to fibrosis and organ dysfunction.

Conclusions:

• The ECM plays a multifaceted role in sepsis pathophysiology.
• ECM dynamics significantly impact cellular signaling, tissue repair, and organ function during sepsis.
• Understanding ECM's role is vital for developing therapeutic strategies for sepsis.
