    α-synuclein expression is not mediated by β2-adrenoreceptor modulation in human dopaminergic cells

    M. Langmyhr, IH. Flønes, CC. Cappelletti, C. Tzoulis, M. Toft (Oslo, Norway)

    Objective: Modulation of the β2-adrenoreceptor (also called the β2-adrenergic receptor or β2-adrenoceptor) has been reported to regulate SNCA expression. We sought to determine the expression…
