Genetic Rodent Models of Huntington Disease.

Area of Science:

• Neuroscience
• Genetics
• Animal Models

Background:

• Huntington disease (HD) is a monogenic disorder.
• Rodent models are the most utilized for HD research and preclinical studies.

Purpose of the Study:

• To compare and discuss commonly used rodent models of Huntington disease.
• To evaluate their relevance to human HD and guide model selection for investigations.

Main Methods:

• Classification of rodent HD models into three main groups: transgenic fragment, transgenic full-length, and knock-in models.
• Comparison of the similarities and differences among these models.

Main Results:

• Rodent models exhibit HD-like characteristics mirroring human clinical symptoms.
• These models are invaluable for understanding HD pathology and developing treatments.

Conclusions:

• Rodent models are essential tools for advancing Huntington disease research.
• Understanding model specificities aids in selecting appropriate models for targeted investigations.
