title: Demented flies? Using Drosophila to model human neurodegenerative diseases.
abstract: The success of biomedical research in the past few decades has led to dramatic improvements in human health and, as a result, increased life expectancy. An unexpected consequence, however, has been an increase in the number of age-related diseases and, in particular, neurodegenerative diseases. Despite their prevalence, a therapeutic void exists in part due to an incomplete understanding of the biochemical pathogenesis of these diseases. A powerful method that can be used to understand the basic mechanisms underlying neurodegenerative diseases is to generate animal models based on manipulating the expression of single genes that are disease causative. This approach has been facilitated by the fact that many neurodegenerative diseases are inherited as autosomal dominant traits such that expression of the mutant gene in a model organism might be expected to recapitulate the disease. During the past few years, the fruit fly, Drosophila melanogaster, has emerged as a powerful tool to model human neurodegenerative diseases. Here, we describe the various approaches utilized to create fly models of human neurodegenerative disease, and how they can aid in our understanding of disease pathogenesis and facilitate drug discovery and testing.
