Abstract:
Background: Animal models for drug discovery and development in Parkinson ’s disease
have played an important role in the characterization of the pathophysiology of diseases and associated
mechanisms of injury, drug target identification, and evaluation of novel therapeutic agents for toxicity/
safety, pharmacokinetics, pharmacodynamics, and efficacy.
Objective: The review is intended to reform the scope, advantages, and limitations of various Parkinson’s
Disease models and their scope in translational research. The lack of a gold standard for PD animal
models presents a major challenge in devising a validation system. This review is an attempt to
provide a way to adopt the validation approach for PD animal model for research.
Methods: Because underlying disease mechanisms are so similar across species, it is possible to extrapolate
results from Parkinson's disease studies using animal models. Furthermore, behavioural tests
used to access the neurobehavioral test with its limitations were explored for rodents, non-human primates,
lower-order animals, and invertebrates. The role of gender selectivity and non-selectivity is the
one major concern in PD model validation that is addressed in the review.
Results: The rigorous validation has been done on animal models for Parkinson's disease (PD) based on
comparisons to the human state. Regarding toxicological and safety investigations in PD, non-animal
options must be thoroughly validated. There are both advantages and disadvantages to using animal
models of Parkinson's disease as proof-of-concept research.
Conclusion: The specific animal model selected for a given drug to be tested and developed depends
on the goal of the specific study.
