    Amelioration of Levodopa-induced Dyskinesias using Genetic Silencing of Striatal CaV1.3 in Parkinsonian Rats: Impact of Sex and Advancing Age

    M. Caulfield, F. Manfredsson, J. Stancati, C. Sortwell, S. Boezwinkle, M. Vanderwerp, T. Collier, K. Collier (Grand Rapids, USA)

    Objective: To advance understanding of striatal CaV1.3 (cacna1d) channel silencing as a therapeutic approach to reduce levodopa-induced dyskinesias (LID), a side effect of long-term escalating…

    Effect of the mGlu2/3 orthosteric agonist LY-404,039 on dyskinesia, psychosis-like behaviours, and parkinsonism in the MPTP-lesioned marmoset

    W. Kang, S. Nuara, J. Gourdon, P. Huot (Montreal, Canada)

    Objective: To assess the effect of LY-404,039 on dyskinesia, psychosis-like behaviours (PLBs) and parkinsonism in the 1-methyl-4-phenyl-1,2,3,6-tetrahydropyridine (MPTP)-lesioned marmoset model of Parkinson’s disease (PD). Background:…

    A dose-response study of the effect of the mGlu2/3 orthosteric antagonist LY-341,495 on the anti-dyskinetic and anti-psychotic effect of the mGlu2 positive allosteric modulator LY-487,379 in the MPTP-lesioned marmoset

    S. Nuara, J. Gourdon, P. Huot (Montreal, Canada)

    Objective: To assess the effects of different doses of the metabotropic glutamate 2 and 3 (mGlu2/3) orthosteric antagonist (OA) LY-341,495 on the anti-dyskinetic and anti-psychotic…
