Summary
Predicting drug-induced liver injury (hepatotoxicity) using in vitro methods is crucial for safer drug development. This review explores alternative approaches to human hepatocytes for reliable toxicity testing.
Area of Science:
- Drug development and toxicology
- Biomedical engineering
- Cell biology
Background:
- Drug-induced liver injury (hepatotoxicity) frequently leads to market withdrawal.
- Current gold standard, human hepatocytes, present challenges in availability and metabolic stability.
- Reliable in vitro predictive tests are needed to reduce drug development costs and animal testing.
Purpose of the Study:
- To review various in vitro approaches developed to predict drug hepatotoxicity.
- To discuss the capabilities and constraints of these alternative methods.
- To explore future directions and opportunities in hepatotoxicity testing.
Main Methods:
- Literature review of in vitro models for hepatotoxicity assessment.
- Analysis of different cell-based assays and engineered systems.
- Discussion of established and emerging technologies.
Main Results:
- Multiple in vitro strategies have been developed to overcome limitations of primary hepatocytes.
- These approaches offer varying degrees of predictive accuracy and scalability.
- Challenges remain in fully replicating the complexity of human liver function in vitro.
Conclusions:
- Alternative in vitro models show promise for predicting drug hepatotoxicity.
- Further research is needed to optimize these systems for clinical translation.
- Advancements in this field can significantly improve drug safety and efficiency.
