Discoidin domain receptor-1 and periostin: new players in chronic kidney disease

Area of Science:

• Nephrology
• Molecular Biology
• Pathology

Background:

• Chronic kidney disease (CKD) poses a significant public health challenge, with renal fibrosis being a primary driver of disease progression.
• Renal fibrosis arises from an imbalance between pro- and anti-fibrotic factors, impacting kidney function.
• Tyrosine kinase receptors (RTKs) and matricellular proteins (MPs) are emerging as critical regulators of renal injury and fibrosis.

Purpose of the Study:

• To review the pathological roles of Discoidin domain receptor-1 (DDR-1), a tyrosine kinase receptor, and periostin, a matricellular protein, in the context of kidney diseases.
• To examine the involvement of DDR-1 and periostin in renal fibrosis using both experimental models and human studies.
• To elucidate the mechanisms by which DDR-1 and periostin modulate renal injury, inflammation, and extracellular matrix deposition.

Main Methods:

• Literature review of studies investigating DDR-1 and periostin in renal fibrosis.
• Analysis of experimental models of kidney disease to understand the roles of DDR-1 and periostin.
• Examination of human nephropathy data to correlate DDR-1 and periostin expression with disease progression.

Main Results:

• Discoidin domain receptor-1 (DDR-1) modulates inflammatory cell recruitment, extracellular matrix deposition, and fibrosis in renal diseases, potentially independent of the underlying cause.
• Periostin, a matricellular protein, mediates cell-matrix interactions, inflammatory cell migration, and fibrosis development, and has been recently implicated in various nephropathies.
• Both DDR-1 and periostin appear to play significant roles in the pathogenesis of renal fibrosis.

Conclusions:

• DDR-1 and periostin represent potential therapeutic targets for mitigating renal fibrosis and managing chronic kidney disease.
• Further research into the specific pathways regulated by DDR-1 and periostin is warranted to develop targeted interventions.
• Understanding the interplay between RTKs and MPs in renal fibrosis is crucial for advancing CKD treatment strategies.
