Area of Science:

  • Neuroscience
  • Genetics
  • Animal Models

Background:

  • Aging populations face increasing neurodegenerative disorders (Alzheimer's, Parkinson's).
  • Genetically modified pigs offer significant advantages over rodent models for preclinical research due to physiological and neurological similarities to humans.
  • Developing accurate animal models is crucial for understanding disease mechanisms and testing therapies.

Purpose of the Study:

  • To provide a neuroanatomical overview of pigs relevant to neurodegenerative disease research.
  • To review the generation and characterization of genetically modified pig models for various neurodegenerative disorders.
  • To propose an innovative approach for efficient generation of these models.

Main Methods:

  • Review of existing literature on genetically modified pig models for neurodegenerative diseases.
  • Neuroanatomical overview of pigs.
  • Discussion of bioimaging (PET, CT, MRI) and behavioral testing for model characterization.
  • Proposal of a multiplex genome editing and preterm recloning (MAP) approach using CRISPR/Cas9 and SCNT.

Main Results:

  • Genetically modified pigs are being developed for Alzheimer's, Parkinson's, Huntington's, ALS, SMA, and Ataxia-Telangiectasia.
  • Non-invasive imaging and behavioral tests are effective for characterizing these models.
  • The proposed MAP approach aims to expedite model generation and improve founder survival.

Conclusions:

  • Genetically modified pigs represent a vital translational bridge for neurodegenerative disease research.
  • The MAP approach holds potential to accelerate the development of more accurate and relevant disease models.
  • Further development of these models is essential for advancing diagnosis, treatment, and prevention strategies.
