Heat Shock Protein 90 in Sepsis-Induced Cardiomyopathy: Mechanistic Insights and Emerging Therapeutic Target

Area of Science:

• Cardiology and Molecular Biology
• Focuses on the molecular mechanisms underlying cardiac dysfunction in sepsis.

Background:

• Sepsis-induced cardiomyopathy (SIC) is a critical cardiac complication of sepsis.
• Pathogenesis involves endogenous danger signals affecting cellular processes.
• Heat Shock Protein 90 (Hsp90), a molecular chaperone, is implicated but not fully understood in SIC.

Purpose of the Study:

• To systematically review the structure and regulatory mechanisms of Hsp90 in SIC.
• To summarize recent advances in Hsp90 inhibitors for potential therapeutic applications.

Main Methods:

• Systematic literature review of Hsp90's role in sepsis-induced cardiomyopathy.
• Categorization and discussion of various Hsp90 inhibitors (natural, functional, structural).

Main Results:

• Hsp90 is vital for apoptosis, oxidative stress, mitochondrial autophagy, immune response, and fibroblast function in SIC.
• Identified Hsp90 inhibitors fall into three main categories: natural product-derived, functional, and structural disruptors.

Conclusions:

• Hsp90 plays a multifaceted role in the pathophysiology of SIC.
• Hsp90 inhibitors represent a promising therapeutic avenue for treating sepsis-induced cardiomyopathy.
