X-linked IAP protein is a potent inhibitor of cell death. Here, we describe a novel transgenic mouse in which the human XIAP gene is expressed under the control of the neuron-specific enolase promoter (NSE-xiap). We demonstrate that nigrostriatal dopamine neurons of NSE-xiap mice were resistant to the damaging effects of the dopaminergic neurotoxin MPTP. MPTP-induced reduction of striatal dopamine metabolism was also attenuated in NSE-xiap mice. Furthermore, NSE-xiap mice treated with MPTP did not exhibit deficits in exploratory behaviour in an open-field test. Taken together, these findings suggest that strategies to enhance neuronal expression of XIAP may provide therapeutic benefit for the treatment of neurodegeneration in Parkinson's disease.
