Effect of treatment with Rapamycin, trehalose, or their combination on autophagy activity measured by quantified immunoreactivity of LC3-II in the s. nigra. MPTP is administered at the dose of 20 mg/kg (i.p., daily) for 4 days to induce PD-like pathology.
Effect of treatment with Rapamycin, trehalose, or their combination on tyrosine hydroxylase (TH) expression in the striatum in MPTP-induced mouse model of Parkinson’s disease.
RNA 5hmC decreases in a MPTP-induced Parkinson's disease mouse model. MPTP (i.p. 60 mg/kg) is injected to induce Parkinson's disease model in mice. At 24 h after last MPTP injection, open field test is performed. After behavioral tests, the hippocampus (Hipo), the substantia nigra (SN), the striatum (Str), and the cortex (Ctx) are collected and total RNA is extracted. Total 100 ng RNA is used for dot blot analysis to detect 5hmC abundance in RNA samples from different brain regions. Methylene bl

MPTP hydrochloride is a brain penetrant dopamine neurotoxin. MPTP hydrochloride can be used to induces Parkinson’s Disease model. MPTP hydrochloride, a precusor of MPP+, induces apoptosis[1][2][3]. MPTP hydrochloride has been verified by MCE with professional biological experiments.
In Vitro
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].

In Vivo
Although MPTP can be administered by a variety of different routes, including oral gavage and stereotaxic injection into the brain, the most common, and reproducible, results are obtained by systemic subcutaneous (s.c.) or intraperitoneal (i.p.) injection.
The commonly used protocols in the references are acute model (14-20 mg/kg, i.p., given every 2 hours within a day, a total of 4 times) and subacute model (30 mg/kg, i.p., once daily for 5 days). MPTP is quickly metabolized to MPP+ after injection, and MPP+ has a half-life of about 6 days in sheep (serum). MPTP hydrochloride can be used in animal modeling to build Parkinson's syndrome models. MPTP reproduces the naturally occurring neurodegeneration and are useful for studying dopaminergic neuron neurodegeneration, mitochondrial dysfunction and neuroinflammation[8].
Induction of Parkinsonism model[4][5][6][7]
Background
MPTP is free to cross the blood-brain barrier and enter the brain, where it is metabolized by monoamine oxidase B (MAO-B) in astrocytes into MPP+, its active & toxic form. MPP+ is taken up by dopamine neurons via a dopamine transporter (DAT), blocking Complex I in the electron transport chain of mitochondria, triggering oxidative stress and mitochondrial breakdown, and finally leading to neuron apoptosis. In Parkinson's disease, it is the loss of neurons in the substantia nigra, the dopamine-producing part of the substantia nigrostriatum system, that causes the disease. Due to the toxic effects of MPTP, it will cause the death of dopamine neurons in the substantia nigra, causing symptoms similar to Parkinson's disease.
Specific Mmodeling Methods
Mice: C57BL/6 • male • 8-12 week-old (period: 2 weeks), older mice may be more sensitive
Administration: Acute model: 14-20 mg/kg • ip • 4 times a day, two hours apart Sub-acute model: 30 mg/kg • ip • once daily for 5 days
Note
MPTP Hcl is dissolved in normal saline and configured when used.
After administration, we can observe whether the mice have symptoms such as reduced activity, staggering walking, twitching, fried hair, increased urination, etc. This behavior may last for 24-48 hours, after which the mice behave basically normally.
MPTP is usually sold as MPTP hydrochloride. The molecular weight of MPTP hydrochloride is 209.7. Therefore, it is recommended to take into account the presence of hydrochloride (HCl) when preparing injectable solutions. HCl has a molecular weight of 35.4 and accounts for 17% of MPTP. Thus, if a 20 mg/kg dose of MPTP is to be prepared, the MPTP hydrochloride dose administered is 20 mg kg* 1.17% = 23.4 mg/kg.
If multiple injections are given within 1 day, it is best to alternate the injections on both sides. If injected every day, it should be done at the same time. Before each injection, the mice need to be weighed and the dosage volume should be adjusted.
Modeling mice may not show behavioral defects of Parkinson's disease. Mice may show individual differences, and the success rate of modeling is generally difficult to reach 100%. Therefore nigrostriatal damage associated with gliosis should be mainly monitored in MPTP mouse studies.
High drug dosage/mice weighing less than 22 g/mixing of drugs from different batches/mice not adapting in advance/animal room being too cold may result in a number of deaths, and it is recommended that the number of animals in each group be increased.
Modeling Record
Nigrostriatal injury: Tyrosine hydroxylase in the substantia nigra and striatum is reduced after successful modeling (IHC, IF, WB, etc.);
Other markers: reduction of brain neurotransmitters (DA, DOPAC, 5-HT, HVA, etc.) (detected by HPLC);
Nigrostriatal microglia (IBA1+ cells) and astrocytes (GFAP+ cells) are activated, and the number of α-syn aggregates in the substantia nigra .

Animal Administration
[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.

Do most proteins show cross-species activity?
Species cross-reactivity must be investigated individually for each product. Many human cytokines will produce a nice response in mouse cell lines, and many mouse proteins will show activity on human cells. Other proteins may have a lower specific activity when used in the opposite species.
