Modeling Parkinson's Disease: Not Only Rodents?

Area of Science:

• Neurodegenerative Diseases
• Genetics
• Pathogenesis

Background:

• Parkinson's disease (PD) is a progressive neurodegenerative disorder with both sporadic and inherited forms.
• Mutations in seven genes (SNCA, LRRK2, VPS35, PRKN, PINK1, GBA, DJ-1) are confirmed causes of familial PD.
• Genetic variability at 90 loci is linked to PD risk, implicating mitochondrial and lysosomal dysfunction, and immune processes.

Purpose of the Study:

• To review and analyze diverse in vivo models for studying Parkinson's disease pathogenesis.
• To explore the utility of various organisms in modeling early-stage PD mechanisms.
• To understand the pathological processes of PD from its earliest stages.

Main Methods:

• Review of studies published since the 2000s focusing on PD models.
• Analysis of toxic rodent models.
• Inclusion of in vivo models using diverse organisms: yeast, nematodes, Drosophila, and mammals.

Main Results:

• Toxic rodent models are predominantly used.
• Diverse organisms offer valuable insights into PD pathogenesis.
• Modeling allows in-depth study of pathological processes from early stages.

Conclusions:

• Various PD models, including non-mammalian organisms, are crucial for understanding disease mechanisms.
• Studying diverse models aids in elucidating the complex pathogenesis of Parkinson's disease.
• Research into early-stage PD is facilitated by comprehensive analysis of these models.
