Targeting lipid-fibrotic signaling crosstalk for antifibrotic therapy

Area of Science:

• Biochemistry
• Cell Biology
• Pathology

Background:

• Fibrosis is a pathological wound-healing response characterized by excessive extracellular matrix accumulation, leading to organ failure.
• Key fibrotic drivers include transforming growth factor-β, Wnt/β-catenin, nuclear factor kappa-B, and sphingosine-1-phosphate signaling.
• Emerging evidence highlights the crucial role of lipid metabolism in regulating these fibrotic pathways.

Purpose of the Study:

• To review the intricate relationship between lipid metabolism and fibrotic signaling pathways across various organ systems.
• To elucidate how lipid-derived mediators drive profibrotic transcriptional programs and metabolic reprogramming.
• To identify novel biomarkers and therapeutic targets within the lipid-fibrosis axis.

Main Methods:

• Literature review and synthesis of current research on lipid metabolism and fibrosis.
• Analysis of the bidirectional crosstalk between fibrotic signaling and lipid pathways.
• Identification of lipid-mediated feed-forward loops sustaining fibrotic processes.

Main Results:

• Lipids are not merely structural components but actively regulate inflammation, oxidative stress, and cell fate (e.g., myofibroblast differentiation).
• Dysregulated lipid synthesis, remodeling, and oxidation create a pro-fibrotic metabolic environment.
• Lipid mediators integrate profibrotic signaling with metabolic reprogramming, establishing self-sustaining fibrotic loops.

Conclusions:

• The lipid-fibrosis axis represents a critical nexus in fibrotic diseases.
• Targeting lipid metabolism and signaling pathways presents a promising strategy for precision antifibrotic interventions.
• Understanding the lipid-fibrosis axis can reveal novel biomarkers and therapeutic targets for treating fibrotic conditions.
