Unconventional Non-rodent Models in Neurological Research: Exploring New Paths to Translational Insights

Area of Science:

• Neuroscience
• Genetics
• Pharmacology

Background:

• Neurological disorders (Alzheimer's, Parkinson's, Huntington's, Schizophrenia, epilepsy) present a growing global health challenge, especially for aging populations.
• Limited translational success of current rodent models necessitates exploring alternative systems for disease research.
• Alzheimer's cases are projected to double in 30 years, highlighting the urgent need for effective treatments and reduced socioeconomic burdens.

Purpose of the Study:

• To review the integration and advantages of non-rodent models in neurological disorder research.
• To highlight emerging alternative systems and their potential for advancing therapeutic strategies.
• To emphasize the need for diverse model systems to improve translational relevance.

Main Methods:

• Review of current literature on non-rodent models for neurological disorders.
• Inclusion of invertebrates (Drosophila, C. elegans), lower vertebrates (Danio rerio), and higher-order mammals (non-human primates).
• Exploration of emerging models: Octopus models, 2D/3D cell cultures, computational, and in silico methodologies.

Main Results:

• Non-rodent models offer unique advantages for studying neural development, function, and pathology.
• Alternative systems demonstrate improved translational relevance compared to traditional rodent models.
• Integration of diverse models enhances the understanding of complex neurological disease mechanisms.

Conclusions:

• Leveraging complementary strengths of various model systems is key to refining therapeutic strategies.
• Alternative models are essential for advancing research into complex neurological disorders.
• Further exploration and integration of these models promise significant breakthroughs in treatment and understanding.
