MPTP hydrochloride is a brain penetrant dopamine neurotoxin, inducing Parkinson’s Disease. MPTP hydrochloride, a precusor of MPP⁺, induces apoptosis^[1][2][3].

Pretreatment with 50 mM 4-phenylpyridine, reduces IC₅₀ (concentration for 50% inhibition of twitch amplitude) values of MPTP from 53 to 18 mM and d-tubocurarine from 0.7 to 0.3 mM, respectively, in mouse phrenic nerve-diaphragm^[2].

The toxic effect of MPTP can be completely abolished in vivo by treatment with a monoamine oxidase inhibitor and potentiated by an inhibitor of catechol-O-methyltransferase^[1]. Gas1 expressions are significantly elevated in the majority of the reactive astrocytes of the brains with LPS or MPTP insults in animal models^[3].

For the preparation of the LPS rat model and the MPTP mouse model, the treatments of the animals are performed. Briefly, adult rats receive unilateral injections of LPS (0.5 μL of 10 μg/μL diluted in 0.9% saline) into the medial forebrain bundle (MFB) at the following coordinates, AP-4.2 mm, L 1.5 mm, and V 7.8 mm, and into the contralateral side with the same volume of 0.9% saline. Adult mice are administered intraperitoneal injections of MPTP of 25 mg/kg per day for five continuous days, and the same volume of saline is injected as a control. All the animals are sacrificed at week 1, 2, 3, or 4 after the LPS or MPTP injections. The brain samples are collected for the subsequent immunohistochemistry and western blot experiments.
