Abstract:
Organ fibrogenesis is characterized by a common pathophysiological final pathway independent of the underlying progressive disease of the respective organ. This makes it particularly suitable as a therapeutic target. The Transregional Collaborative Research Center "Organ Fibrosis: From Mechanisms of Injury to Modulation of Disease" (referred to as SFB/TRR57) was hosted from 2009 to 2021 by the Medical Faculties of RWTH Aachen University and the University of Bonn. This consortium had the ultimate goal of discovering new common but also different fibrosis pathways in the liver and kidneys. It finally successfully identified new mechanisms and established novel therapeutic approaches to interfere with hepatic and renal fibrosis. This review covers the consortium's key kidney-related findings, where three overarching questions were addressed: (i) What are new relevant mechanisms and signaling pathways triggering renal fibrosis? (ii) What are new immunological mechanisms, cells and molecules that contribute to renal fibrosis?, and finally (iii) How can renal fibrosis be modulated?
Insights
Researchers explored kidney fibrosis mechanisms and immune roles, identifying new therapeutic targets. This work aimed to find novel pathways to modulate renal fibrosis, offering hope for new treatments.
Area of Science:
- Nephrology
- Immunology
- Pathophysiology
Background:
- Organ fibrogenesis represents a common pathway in progressive organ diseases, making it a viable therapeutic target.
- The SFB/TRR57 consortium focused on understanding shared and distinct fibrosis mechanisms in the liver and kidneys.
- Previous research highlighted the need for novel strategies to combat renal fibrosis.
Purpose of the Study:
- To elucidate novel mechanisms and signaling pathways driving renal fibrosis.
- To investigate the immunological factors, cells, and molecules involved in renal fibrosis.
- To identify and evaluate new therapeutic approaches for modulating kidney fibrosis.
Main Methods:
- Consortium-based research integrating molecular biology, immunology, and pathology.
- Analysis of signaling pathways implicated in fibrotic processes.
- Characterization of immune cell populations and their contribution to renal damage.
Main Results:
- Identification of previously unknown mechanisms and signaling pathways contributing to renal fibrosis.
- Elucidation of key immunological players and their roles in the progression of kidney fibrosis.
- Development of novel therapeutic strategies targeting identified fibrotic pathways.
Conclusions:
- Renal fibrosis involves complex mechanisms and immunological components that can be targeted therapeutically.
- The findings provide a foundation for developing innovative treatments for kidney fibrosis.
- Modulating specific pathways offers a promising avenue for managing fibrotic kidney diseases.
