Velopment of new therapies for the treatment of neurological and psychiatric disorders. To be able to enhance drug discovery and improvement Bombesin Receptor Formulation activities inside the CNS field, the division of translational study (DTR) inside NINDS, and in concert with other NIH-institutes, launched a series of translational applications to boost neuroscience drug discovery and development efforts to mitigate the current pipeline gaps. These translational applications are milestones-driven cooperative agreements (The Blueprint Neurotherapeutics Network; Biotechnology Items and Biologics; Smaller organization programs, Therapeutic and diagnostic devices, Devices to Treat Discomfort); grants-driven (Innovation Grants to Nurture Initial Translational Efforts; Biomarker Initiatives: Neurological Disorders and Pain, Therapeutics for Treating Chemical Injuries) or screening applications such as Epilepsy Therapy Screening Program and Preclinical Screening Platform for Discomfort. Within this poster, we outline to neuroscientists in academia and industry the distinctive NINDS/DTR-funding mechanisms and sources to support their drug discovery initiatives or ongoing preclinical and translational activities within the field of neuroscience. Abstract 29 Securing Bench to Bedside Translation with Predictive EEG Biomarkers of Parkinson’s Illness Venceslas Duveau, Julien Volle, ChloHabermacher, Alexis Evrard, Hedi Gharbi, Corinne Roucard, Yann Roche; all SynapCell Parkinson’s disease (PD) is often a slowly progressive and disabling neurodegenerative disorder affecting an estimated 7 to ten million people today worldwide. Regardless of current advances in drug development, dopaminergic drugs such as L-DOPAASENT2021 Annual Meeting Abstractsremain today’s standard-of-care, regardless of the side-effects it’s inducing inside the long-term. To gain in effectiveness, translational analysis wants clinically relevant animal models of PD that show comparable pathophysiological and functional traits than the ones identified in human individuals. The broadly adopted 6-OHDA rat model is one of them and expresses precisely the same aberrant EEG oscillatory patterns as those characterized within the clinic, making the model hugely predictive for drug discovery. State-of-the-art clinical literature shows that motor symptoms of Parkinson’s illness outcome from a dysfunction from the cortico-basal ganglia circuits. A hyper synchronization of beta rhythms within this circuit, positively correlated to motor symptoms, has been characterized in each parkinsonian sufferers and animal models. This aberrant excessive beta 5-HT4 Receptor manufacturer oscillation is suppressed by dopaminergic treatment options, and which enhance motor deficits at the identical time. A chronic L-DOPA therapy induces abnormal involuntary movements (AIMs) as well as a prominent resonant gamma oscillation. This project aimed at investigating the impact of an acute injection of the antidyskinetic drug amantadine on L-DOPA low dose-induced gamma oscillations in the 6-OHDA rat. Unilaterally 6-OHDA-lesioned rats have been implanted with a bipolar electrode in the motor cortex ipsilateral in the lesion. On 1 hand, the acute effect of dopaminergic drugs was evaluated on the abnormal beta oscillation. Alternatively, 6-OHDA-lesioned rats were treated each day for two weeks with 6 mg/kg L-DOPA to induce stable gamma oscillations, which have been monitored at days 1, 5, 8, 12, and 15 employing EEG recordings. The effects of pre-treatments with either car or amantadine (45 or 90 mg/kg) 120 min before L-DOPA injection was then evaluated on gamma oscillations and L-DOPA induced.
