Inflammation and renal fibrosis: Recent developments on key signaling molecules as potential therapeutic targets

Area of Science:

• Nephrology
• Immunology
• Pathology

Background:

• Chronic kidney disease (CKD) is a significant global health concern.
• Renal fibrosis, a common endpoint in kidney disease progression, is increasingly linked to inflammatory processes.
• Key inflammatory mediators like MCP-1, B1R, NF-κB, TNFα, TGF-β, and PDGF are implicated in CKD pathogenesis.

Purpose of the Study:

• To review the role of cytokine pathways and inflammatory cell infiltration in CKD.
• To explore the balance between pro- and antifibrotic signaling in kidney disease.
• To identify therapeutic targets for novel antifibrotic strategies in CKD.

Main Methods:

• Literature review of existing research on renal inflammation and fibrosis in CKD.
• Analysis of signaling pathways involving pro- and antifibrotic factors.
• Synthesis of knowledge on inflammatory cell infiltration in kidney disease.

Main Results:

• Inflammation is central to the initiation and progression of CKD.
• Dysregulation of specific cytokine pathways (e.g., MCP-1, TNFα, TGF-β) contributes to renal fibrosis.
• Downregulation of protective factors (e.g., IL-10, IFN-γ, BMP-7, HGF) exacerbates kidney damage.

Conclusions:

• Restoring the balance between pro- and antifibrotic signaling is a promising therapeutic principle for CKD.
• Targeting multiple pathways simultaneously may be necessary for effective antifibrotic therapies.
• Further research into cytokine pathways and inflammation is crucial for developing novel treatments to prevent CKD progression.
