Among the popular animal models of Parkinson's disease (PD) commonly used in research are those that employ neurotoxins, especially 1-methyl- 4-phenyl-1, 2, 3, 6-tetrahydropyridine (MPTP). This neurotoxin exerts it neurotoxicity by causing a barrage of insults, such as oxidative stress, mitochondrial apoptosis, inflammation, excitotoxicity, and formation of inclusion bodies acting singly and in concert, ultimately leading to dopaminergic neuronal damage in the substantia nigra pars compacta and striatum. The selective neurotoxicity induced by MPTP in the nigrostriatal dopaminergic neurons of the mouse brain has led to new perspectives on PD. For decades, the MPTP-induced mouse model of PD has been the gold standard in PD research even though it does not fully recapitulate PD symptomatology, but it does have the advantages of simplicity, practicability, affordability, and fewer ethical considerations and greater clinical correlation than those of other toxin models of PD. The model has rejuvenated PD research and opened new frontiers in the quest for more novel therapeutic and adjuvant agents for PD. Hence, this review summarizes the role of MPTP in producing Parkinson-like symptoms in mice and the experimental role of the MPTP-induced mouse model. We discussed recent developments of more promising PD therapeutics to enrich our existing knowledge about this neurotoxin using this model.

Parkinson's disease (PD) is a prevalent and challenging neurodegenerative disorder, and may involve impaired autophagy. Nuclear factor erythroid-2-related factor 2 (Nrf2) is crucial for regulating autophagy-related genes, maintaining cellular homeostasis. Electroacupuncture (EA), a complementary and alternative therapy for PD, has gained widespread clinical application.

Cinnamaldehyde (CA), the primary bioactive compound in cinnamon ( Presl, Lauraceae, ), holds potential therapeutic benefits for Parkinson's disease (PD). To scrutinize the impact and mechanisms of CA on 1-methyl-4-phenyl-1,2,3,6-tetrahydropyridine (MPTP)-induced PD, male C57BL/6 mice were randomly allocated to CA (150, 300, and 600 mg/kg), model, Madopar, and control group ( = 12). The Open Field, Pole-jump, and Rotarod experiments assessed exercise capacity and anxiety levels.

Objectives: To investigate the role of mitochondrial autophagy disorder caused by deletion of E3 ubiquitin ligase Parkin in neuroinflammation in a mouse model of MPTP-induced Parkinson's disease (PD).
Methods: Wild-type (WT) male C57BL/6 mice and Parkin mice were given intraperitoneal injections with MPTP or PBS for 5 consecutive days, and the changes in motor behaviors of the mice were observed using open field test. The effects of Parkin deletion on PD development and neuroinflammation were evaluated using immunofluorescence and Western blotting.

Neuroinflammation induced by activation of microglial is a vital contributor to progression of Parkinson's disease (PD), emerging evidences suggested that ferroptosis played a pivotal role in microglial activation and subsequent dopaminergic neuron loss. Nevertheless, the fundamental pathogenesis of that ferroptosis contributes to PD is not yet sufficiently understood. Based on GEO dataset, ferroptosis related genes were found to be enriched in PD patients and MPTP mouse model of PD, among them, ATF4 was found to be dramatically differentially expressed.

Parkinson's disease (PD) is a neurodegenerative disease characterized by the loss of dopaminergic neurons. In particular, neuroinflammation associated with phosphorylation of c-Jun N-terminal kinase (JNK) is likely to cause the death of dopaminergic neurons. Therefore, protecting dopaminergic neurons through anti-neuroinflammation is a promising therapeutic strategy for PD.
