Animal models of Huntington's disease. Pros and cons

Area of Science:

• Neurology
• Genetics
• Animal Models

Background:

• Huntington's disease (HD) is a neurological disorder affecting specific brain circuits.
• Modeling HD involves neurotoxic compounds and diverse animal models, including genetic variants.

Purpose of the Study:

• To review available animal models for studying Huntington's disease.
• To highlight the advantages and disadvantages of each model in recapitulating HD pathology and progression.
• To identify knowledge gaps and guide future research for improved therapeutic strategies.

Main Methods:

• Review of existing literature on animal models for Huntington's disease.
• Classification of genetic models based on specific constructs (gene fragments, full-length, knock-out, knock-in).
• Analysis of model utility in studying neuropathology, behavioral alterations, and disease mechanisms.

Main Results:

• Various animal models exist for HD, each with specific strengths and limitations.
• Genetic models offer different ways to study HD-related gene mutations.
• Current models face challenges in fully replicating the complexity of human HD.

Conclusions:

• Animal models are crucial for understanding Huntington's disease progression and mechanisms.
• Further research is needed to bridge knowledge gaps and enhance the translational relevance of these models.
• Improved models and patient data integration are key to developing effective treatments for HD.
