NF-kappaB signalling in chronic kidney disease

Area of Science:

• Molecular Biology
• Immunology
• Nephrology

Background:

• The nuclear factor kappa B (NF-κB) pathway is a key intracellular transcription factor system activated by external stimuli.
• NF-κB regulates genes involved in inflammation, immunity, apoptosis, and cell growth.
• Components like cell-surface receptors, kinases, and inhibitory proteins modulate NF-κB activation.

Purpose of the Study:

• To review current evidence on NF-κB isoforms in chronic kidney disease (CKD).
• To explore the pathogenic role of NF-κB upregulation in CKD.
• To examine the potential of targeting NF-κB isoforms for treating kidney failure.

Main Methods:

• Review of in vitro studies.
• Analysis of animal models.
• Examination of human studies.

Main Results:

• Upregulation of the canonical (RelA/p50) NF-κB isoform is implicated in chronic inflammation in CKD.
• This pathogenic role is observed in tubular epithelial cells, podocytes, mesangial cells, and macrophages.
• Evidence suggests NF-κB isoforms contribute to kidney damage in CKD.

Conclusions:

• The canonical NF-κB isoform plays a significant role in the pathogenesis of CKD.
• Understanding NF-κB isoform activity is crucial for developing targeted therapies.
• Targeting NF-κB pathways presents a potential therapeutic strategy for kidney failure in CKD.
