A virus-induced kidney disease model based on organ-on-a-chip: Pathogenesis exploration of virus-related renal...

Area of Science:

• Nephrology
• Virology
• Biotechnology

Background:

• Viral infections frequently cause renal dysfunction, particularly affecting distal renal tubules, but the underlying pathogenesis is not well understood.
• Understanding virus-induced kidney disease is crucial for developing effective treatments.

Purpose of the Study:

• To investigate the pathogenesis of virus-related renal dysfunctions.
• To establish a novel distal tubule-on-a-chip (DTC) model for studying Pseudorabies Virus (PrV) induced kidney disease.

Main Methods:

• Development of a distal tubule-on-a-chip (DTC) model to successfully reconstitute the barrier structure and sodium (Na) reabsorption of distal renal tubules.
• Infection of the DTC model with Pseudorabies Virus (PrV) to observe its effects on renal tubule function.

Main Results:

• PrV infection led to electrolyte regulation dysfunction, specifically impaired Na reabsorption.
• Observed disruptions included disordered Na transporters, a compromised reabsorption barrier, and altered microvilli structure.
• These changes in the DTC model correlated with virus-induced serum electrolyte abnormalities.

Conclusions:

• The study provides new insights into the pathogenesis of virus-induced renal dysfunction.
• The distal tubule-on-a-chip model demonstrates significant advantages for virus research by accurately reproducing renal tubule functions.
• Organ-on-a-chip technology offers a powerful platform for studying viral pathogenesis and its impact on organ function.
