Abstract:
Interactions between genetic and environmental factors are thought to contribute to the pathogenesis of the majority of Parkinson's disease (PD) cases. However, our understanding of these interactions is at an early stage. Mutations in leucine-rich repeat kinase 2 (LRRK2) are the most common cause of hereditary PD. Penetrance of LRRK2 mutations is incomplete and variable, suggesting that other environmental or genetic factors may contribute to the development of the disorder. Recently, using animal models, several attempts have been made to understand if LRRK2 may mediate sensitivity to environmental neurotoxicants. Here, we critically review the most current data on how LRRK2 mutations influence neurotoxicity in PD models.
Insights
Genetic and environmental factors influence Parkinson's disease (PD). Leucine-rich repeat kinase 2 (LRRK2) mutations, a common cause of hereditary PD, may affect sensitivity to neurotoxicants, as explored in animal models.
Area of Science:
- Neuroscience
- Genetics
- Environmental Health
Background:
- Parkinson's disease (PD) pathogenesis involves complex genetic and environmental interactions, though poorly understood.
- Mutations in leucine-rich repeat kinase 2 (LRRK2) are the leading genetic cause of hereditary PD.
- Incomplete penetrance of LRRK2 mutations suggests additional contributing factors.
Purpose of the Study:
- To critically review current data on the role of LRRK2 mutations in mediating neurotoxicity.
- To explore how LRRK2 influences sensitivity to environmental neurotoxicants in PD models.
Main Methods:
- Literature review of existing studies.
- Analysis of data from animal models investigating LRRK2 and neurotoxicant interactions.
Main Results:
- LRRK2 mutations are implicated in modulating an individual's susceptibility to environmental neurotoxicants.
- Animal models provide insights into the mechanisms by which LRRK2 affects neurotoxicity.
Conclusions:
- Understanding LRRK2's role in neurotoxicity is crucial for elucidating PD pathogenesis.
- Further research is needed to fully grasp the interplay between LRRK2, environment, and PD development.
