Circadian rhythms, Parkinson's disease, and fruit fly research

De Lazzari F, Bisaglia M, Zordan MA, Sandrelli F. Circadian Rhythm Abnormalities in Parkinson's Disease from Humans to Flies and Back. Int J Mol Sci. 2018 Dec 6;19(12). pii: E3911. PMID: 30563246.

From the abstract: "Clinical and research studies have suggested a link between Parkinson's disease (PD) and alterations in the circadian clock. Drosophila melanogaster may represent a useful model to study the relationship between the circadian clock and PD. ... Here, we describe the fly circadian and dopaminergic systems and report recent studies which indicate the presence of circadian abnormalities in some fly PD genetic models. We discuss the use of Drosophila to investigate whether, in adults, the disruption of the circadian system might be causative of brain neurodegeneration. We also consider approaches using Drosophila, which might provide new information ... As a corollary, ... we suggest that genetic models of PD could be used to perform lifelong screens for drug-modulators of general and/or circadian-related PD traits."
