Drosophila models pioneer a new approach to drug discovery for Parkinson's disease

Drug Discovery Today

Abstract

Despite the prevalence and severity of Parkinson's disease (PD), little is known about the molecular etiology of this disease, and preventative and disease-modifying therapies remain elusive. Recently, linkage studies have begun to identify single-gene mutations that are responsible for rare, heritable forms of PD, which offer an opportunity to gain insight into the molecular mechanisms of this disorder through the creation and analysis of appropriate animal models. One model system that is tractable for these studies is the fruit fly, Drosophila melanogaster. Analysis of several Drosophila models of PD has revealed some surprising insights into the pathogenesis of PD and begun to highlight potential treatment strategies.

Alpha-Synuclein Aggregation

Alpha-synucleins are small proteins that are believed to restrict the mobility of synpatic vesicles and inhibit neurotransmitter release. Aggregation of these proteins have been linked to several types of neurodegenerative diseases including dementia with Lewy bodies and Parkinson's disease. Here is the latest research on α-synuclein aggregation.

Atypical Parkinsonism (MDS)

Atypical Parkinsonism presents with the same signs and symptoms of Parkinson's disease, but do not respond to typical Parkionson's disease treatment with levodopa. Atypical Parkinsonism is thought to be associated with abnormal protein buildup within brain cells. Here is the latest on Atypical Parkinsonism.
