Abstract:
Although the pathogenesis of Parkinson disease (PD) is still unclear, various studies have uncovered important clues to the cause of the dopaminergic cell death. Accumulating evidence has suggested that both environmental and genetic factors collaborate and cause dopaminergic cell death. Aging, exposure to pesticides, and endogenous toxic agents, such as dopamine derivatives, mighty induce oxidative stress and lead to neurodegeneration. The studies on familial PD-related genes indicate that impairment of the ubiquitin-proteasome system induces the accumulation of misfolded protein, mainly alpha-synuclein, leading to cell death. This review discusses the possible mechanisms, underlying sporadic and familial PD.
Insights
Parkinson disease (PD) pathogenesis involves environmental and genetic factors causing dopaminergic cell death. Oxidative stress and protein misfolding, particularly alpha-synuclein, are key mechanisms in both sporadic and familial forms.
Area of Science:
- Neuroscience
- Genetics
- Environmental Health
Context:
- Parkinson disease (PD) pathogenesis remains incompletely understood.
- Dopaminergic cell death is a hallmark of PD.
- Both environmental and genetic factors are implicated.
Purpose:
- To review the current understanding of Parkinson disease pathogenesis.
- To discuss the mechanisms underlying dopaminergic cell death in PD.
- To explore factors contributing to both sporadic and familial PD.
Summary:
- PD pathogenesis involves a complex interplay of environmental and genetic factors.
- Oxidative stress, induced by agents like pesticides and dopamine derivatives, contributes to neurodegeneration.
- Impairment of the ubiquitin-proteasome system and alpha-synuclein accumulation are critical in familial PD.
Impact:
- Provides a comprehensive overview of PD pathogenic mechanisms.
- Highlights key molecular and cellular pathways involved in neurodegeneration.
- Informs future research directions for PD prevention and treatment.
