Melior Discovery in vivo models of Parkinson’s Disease
in vivo Efficacy: Animal Models
Melior is a leading contract research provider of preclinical in vivo pharmacology services using rat and mouse models of Parkinson’s Disease.
Melior has a broad array of preclinical models evaluating neurological conditions and neurodegeneration, including Parkinson’s Disease. This area represents one of Melior’s core areas of expertise. Many of these rodent models are a staple part of Melior’s theraTRACE® platform. As a result we have been running these models for many years and run these models routinely.
Parkinson’s Disease Models
- 6-OHDA Rat Model of Parkinson’s Disease
- Drug-Induced Catalepsy Model
- MPTP-Induced Mouse Model of Parkinson’s Disease
6-OHDA Rat Model of Parkinson’s Disease
The neurotoxin 6-hydroxydopamine (6-OHDA) is widely used to induce depletion of dopaminergic neurons in animal models of Parkinson’s Disease (PD). Unilateral administration of 6-OHDA into the medial forebrain bundle can produce a 90-95% ipsilateral depletion of dpn neurons in 80-90% of animals injected, leading to a PD – like motor dysfunction.
MPTP – Induced Parkinson’s Disease Model
MPTP is a potent and selective nigrostriatal dopaminergic neurotoxin that in mice produces many of the neuropathological features of idiopathic Parkinson’s Disease in humans. MPTP produces nigrostriatal dopaminergic degeneration and locomotor impairment. Pharmacological agents that increase dopaminergic function or that block the neurotoxicity of MPTP also attenuate MPTP-associated locomotor and dopaminergic dysfunction. Moreover, MPTP-mediated toxicity may have some relationship to the mechanisms associated with dopaminergic loss in the disease indicating that this model may also be potentially useful for identifying agents that slow or reduce nigrostriatal dopaminergic loss.
