Regulation of alpha-synuclein expression in limbic and motor brain regions of morphine-treated mice.


Chronic exposure to opiates produces dependence and addiction, which may result from neuroadaptations in the dopaminergic reward pathway and its target brain regions. The neuronal protein alpha-synuclein has been implicated in neuronal plasticity and proposed to serve as a negative regulator of dopamine neurotransmission. Thus, alpha-synuclein could mediate… (More)
