The role of gamma-synuclein in cocaine-induced behaviour in rats

Boyer, Frederic ; Dreyer, Jean-Luc

In: European Journal of Neuroscience, 2008, vol. 27, no. 11, p. 2938 - 2951

The aim of this study was to investigate the role of γ-synuclein in the rewarding effects of chronic cocaine administration and its putative interaction with the dopamine transporter (DAT). For this purpose, regulatable lentiviruses driving overexpression of the rat γ-synuclein or DAT have been prepared, as well as lentiviruses expressing siRNAs, aimed at silencing either DAT or γ-synuclein...

Alpha-synuclein in the nucleus accumbens induces changes in cocaine behaviour in rats

Boyer, Frederic ; Dreyer, Jean-Luc

In: European Journal of Neuroscience, 2007, vol. 26, no. 10, p. 2764-2776

The mesolimbic dopaminergic system is widely recognized to be critical to the neurobiology of cocaine reward and addiction. The neuronal protein, α-synuclein, is an important regulator in dopaminergic transmission. It interacts with the dopamine transporter, and regulates dopaminergic content, neurotransmission and synaptic strength of dopaminergic neurons. Alpha-synuclein levels are elevated in...
