Abstract:
Interstitial fibrosis with tubule atrophy (IF/TA) is the response to virtually any sustained kidney injury and correlates inversely with kidney function and allograft survival. IF/TA is driven by various pathways that include hypoxia, renin-angiotensin-aldosterone system, transforming growth factor-β signaling, cellular rejection, inflammation, and others. In this review, we will focus on key pathways in the progress of renal fibrosis, diagnosis and therapy of allograft fibrosis. This review discusses the role and origin of myofibroblasts as matrix producing cells and therapeutic targets in renal fibrosis with a particular focus on renal allografts. We summarize current trends to use multiomic approaches to identify new biomarkers for IF/TA detection and to predict allograft survival. Furthermore, we review current imaging strategies that might help to identify and follow-up IF/TA complementary or as alternative to invasive biopsies. We further discuss current clinical trials and therapeutic strategies to treat kidney fibrosis.
Insights
Interstitial fibrosis with tubule atrophy (IF/TA) is a key factor in kidney injury and allograft survival. This review explores IF/TA pathways, biomarkers, and therapeutic strategies for kidney fibrosis.
Area of Science:
- Nephrology
- Immunology
- Pathology
Background:
- Interstitial fibrosis with tubule atrophy (IF/TA) is a common response to kidney injury, impacting kidney function and allograft survival.
- Multiple pathways, including hypoxia and inflammation, contribute to IF/TA progression.
Purpose of the Study:
- To review key pathways in renal fibrosis development.
- To discuss diagnostic and therapeutic strategies for allograft fibrosis.
- To highlight the role of myofibroblasts in renal fibrosis.
Main Methods:
- Literature review focusing on renal fibrosis pathways, myofibroblast biology, and therapeutic targets.
- Summary of multiomic approaches for biomarker discovery.
- Review of current imaging strategies and clinical trials for IF/TA.
Main Results:
- IF/TA is driven by diverse pathways and myofibroblasts are central matrix-producing cells.
- Multiomic approaches show promise for IF/TA detection and survival prediction.
- Imaging strategies and ongoing clinical trials offer new avenues for managing kidney fibrosis.
Conclusions:
- Understanding IF/TA pathways and myofibroblast biology is crucial for developing effective treatments.
- Novel biomarkers and non-invasive imaging techniques are needed for early IF/TA detection and monitoring.
- Targeted therapies and ongoing clinical trials hold promise for improving outcomes in kidney fibrosis.
