The complexity of the nervous system arises in part, from the large diversity of neural cell types that support the architecture of neuronal circuits. Recent studies have highlighted microRNAs as important players in regulating gene expression at the post-transcriptional level and therefore the phenotype of neural cells. A link between microRNAs and neurodegenerative diseases such as Alzheimer's disease, Huntington's disease and Parkinson's disease is becoming increasingly evident. Here, we discuss microRNAs in neurodegeneration, from the fruit fly and mouse utilized as experimental models to dysregulated microRNAs in human neurodegenerative disorders. We propose that studying microRNAs and their mRNA targets in the context of neurodegeneration will significantly contribute to the identification of proteins important for neuronal function and might reveal underlying molecular networks that drive these diseases.
