Decreasing the expression of genes in a mammalian subject has multiple applications ranging from cancer therapy to anti-infective therapy or treatment of autosomal dominant genetic disorders. Yet, there is still a lack of efficient technologies to achieve that goal in mammalian subjects in vivo. The present invention relates to methods for decreasing gene expression by administering to a mammalian subject a recombinant adeno-associated viral vector in vivo with said vector comprising an RNA interference (RNAi) expression cassette whose RNA expression products directly or indirectly lead to a decrease in expression of the corresponding RNAi target gene. Upon successful transduction with the recombinant adeno-associated viral vector, the RNA expression products of the RNAi expression cassette will decrease the cellular concentration of the mRNA transcripts of the RNAi target gene, thus resulting in decreased concentration of the protein encoded by the RNAi target gene.

Huntington's Disease (HD) is an autosomal-dominant inherited progressive neurodegenerative disease from the group of CAG repeat / polyglutamine diseases and is characterized by a triad of psychiatric alterations, dementia and motor dysfunction. On a sub-cellular level, a mutation with extended CAG tri-nucleotide repeats has been identified as the cause of HD. The therapeutic effects of certain substances can be tested on neurotoxically-induced or transgenic animal models with expanded CAG-repeats. In the present invention, transgenic rats were generated and characterized for human HD. Said rat model for human HD and other diseases of the CNS carries 51 CAG repeats under the control of a rat promoter and has a slow progressive neurological phenotype, closely reflecting human HD syndrome. The comparability of the rat model in relation to human HD is characterized by neuropathological, neuroradiological and neurochemical modifications accompanied by typical behavioral symptoms.

Mutations in the leucine-rich repeat kinase (LRRK2) gene cause late-onset autosomal dominant Parkinson's disease (PD) with pleiomorphic pathology. Previously, we and others found that expression of mutant LRRK2 causes neuronal degeneration in cell culture. Here we used the GAL4 / UAS system to generate transgenic Drosophila expressing either wild-type (WT1) human LRRK2 or LRRK2-G2019S, the most common mutation associated with PD. Expression of either WT1 human LRRK2 or LRRK2-G2019S in the photoreceptor cells caused retinal degeneration. Expression of WT1 LRRK2 or LRRK2-G2019S in neurons produced adult-onset selective loss of dopaminergic neurons, locomotor dysfunction, and early mortality. Expression of mutant G2019S-LRRK2 caused a more severe parkinsonism-like phenotype than expression of equivalent levels of WT1 LRRK2. Treatment with L-DOPA improved mutant LRRK2-induced locomotor impairment but did not prevent the loss of tyrosine hydroxylase (TH)-positive neurons. To our knowledge, this is the first in vivo “gain-of-function” model which recapitulates several key features of LRRK2-linked human parkinsonism. These flies may provide a useful model for studying LRRK2-linked pathogenesis and for future therapeutic screens for PD intervention.
