Abstract:
Parkinson's disease (PD) has been modeled in humans, lower primates, and to a lesser extent in some other vertebrates by the administration of the potent neurotoxin 1-methyl-4-phenyl-1,2,3,6 tetrahydropyridine (MPTP). The MPTP model has thus drawn considerable attention during the past 15 years, as a system to search for anti-PD drugs. It has been previously reported that a Parkinsonian syndrome can be elicited in the common goldfish (Carassius auratus) by a single dose of MPTP. This protocol describes the relatively simple and inexpensive MPTP model of PD in goldfish. The procedure takes 14-30 d, depending on how many animals are tested and on the planned study. The accessibility of the goldfish nervous system, neural density, the evolutionary equivalent subcortical circuitry and the greatly abbreviated blood-brain barrier of the goldfish brain, make it an attractive system for study of PD as well as potential drugs for therapy.
Insights
A simple goldfish model using 1-methyl-4-phenyl-1,2,3,6 tetrahydropyridine (MPTP) effectively mimics Parkinson's disease (PD) symptoms. This accessible model aids in discovering new anti-PD therapies.
Area of Science:
- Neuroscience
- Pharmacology
- Animal Models
Background:
- Parkinson's disease (PD) is a neurodegenerative disorder.
- The 1-methyl-4-phenyl-1,2,3,6 tetrahydropyridine (MPTP) neurotoxin is used to model PD.
- Goldfish (Carassius auratus) have shown potential as a model organism for PD.
Purpose of the Study:
- To describe a simple and cost-effective protocol for modeling Parkinson's disease in goldfish using MPTP.
- To highlight the advantages of using goldfish for PD research and drug discovery.
Main Methods:
- Administration of a single dose of MPTP to common goldfish.
- Observation and assessment of induced Parkinsonian syndrome over 14-30 days.
Main Results:
- MPTP successfully elicits a Parkinsonian syndrome in goldfish.
- The protocol is simple, inexpensive, and adaptable to varying study sizes.
Conclusions:
- Goldfish offer an accessible and valuable model for studying Parkinson's disease.
- The unique neuroanatomical and physiological features of goldfish brains facilitate PD research and therapeutic drug screening.
