Drug-Induced Nephrotoxicity Assessment in 3D Cellular Models

Area of Science:

• Nephrology and Pharmacology
• Toxicology and Drug Safety
• Biomedical Engineering

Background:

• Kidneys are vital organs susceptible to drug toxicity, with drug-induced nephrotoxicity causing significant adverse reactions.
• Current limitations in 2D cell models hinder accurate prediction of in vivo nephrotoxicity due to lack of renal tubule complexity.
• Understanding drug-induced kidney injury mechanisms is critical for developing safer pharmaceuticals.

Purpose of the Study:

• To review the mechanisms of drug-induced kidney injury.
• To evaluate existing in vivo and in vitro nephrotoxicity models.
• To explore the advancements in 3D cellular culture models for improved drug-induced nephrotoxicity research.

Main Methods:

• Review of existing literature on drug-induced nephrotoxicity mechanisms.
• Analysis of current in vivo and in vitro nephrotoxicity testing models.
• Examination of research progress in 3D cellular culture models for kidney research.

Main Results:

• Drug-induced nephrotoxicity involves diverse mechanisms like altered hemodynamics, cytotoxicity, inflammation, and crystal formation.
• Existing 2D cell models do not fully capture the polarized morphology and functional complexity of renal tubules.
• 3D cellular models offer a more physiologically relevant platform for studying kidney cell behavior and drug responses.

Conclusions:

• Accurate prediction of drug-induced nephrotoxicity requires models that recapitulate the kidney's complex microenvironment and cellular architecture.
• 3D cellular culture models represent a promising advancement for more reliable in vitro nephrotoxicity assessments.
• Further research into 3D kidney models is essential for enhancing drug safety and facilitating the development of new therapeutics.
