“…A primary involvement of D1 receptors and the direct basal ganglia pathway is suggested by other recent studies too (Aubert et al, 2005;Fiorentini et al, 2006), and by the fact that D2 family agonists are less likely to induce dyskinesia in patients and animal models of PD than unselective and D1/D5 selective agonists (present findings; Gnanalingham et al, 1995;Blanchet et al, 1996;Pearce et al, 1999;Goulet and Madras, 2000;Nutt, 2000;Rascol et al, 2001;Lundblad et al, 2002;Monville et al, 2005). A recent study established that levodopa-induced dyskinesia in the rat 6-OHDA model is related to increased synchronization of afferent activity to the basal ganglia output nuclei (Meissner et al, 2006). Our present findings suggest that D1 receptor mediated over-activation of a sensitized direct pathway may contribute to driving this abnormal low frequency synchronization in the basal ganglia output nuclei and levodopa-induced dyskinesia.…”

“…Timeline of experiments is depicted on Figure 1 B. Unilateral, 6-OHDA-lesioned, L-dopa/benserazidetreated rats were generated as described previously (Meissner et al, 2006). Male Wistar rats (Charles River, Kingston, NY) (250 -350 gm) were pretreated with desipramine (25 mg/kg, i.p.)…”

“…In vivo: 30 adult male Sprague Dawley rats (Charles River Laboratories) weighing 175-200 g at the beginning of the experiment were used. On day 0 of the protocol, unilateral dopamine deprivation of the striatum was obtained by 6-OHDA (3 g/l) injection in the right medial forebrain bundle (2.5 l at AP ϭ Ϫ3.7 mm, ML ϭ ϩ1.7 mm, and DV ϭ Ϫ8 mm, relative to bregma) as previously described (Meissner et al, 2006;Schuster et al, 2008;Berthet et al, 2009). Animals displaying a loss of TH-immunopositive fibers in the striatum Ͼ95% (Bezard et al, 2001b;Guigoni et al, 2005b), as assessed after completion of all experiments, were retained for final analysis.…”

“…In such conditions, L-DOPA induces a gradual development of AIMs. On day 29, 10 rats were scored as dyskinetic (score ϭ 12) after observation by a trained investigator as previously described (Meissner et al, 2006;Schuster et al, 2008;Schuster et al, 2009), using a validated rating scale (Cenci et al, 1998;Lundblad et al, 2002). On day 30, all animals received the last vehicle injection ϩ/Ϫ L-DOPA.…”
