Velopment of new therapies for the remedy of neurological and psychiatric disorders. In order to increase drug discovery and development activities within the CNS field, the division of translational analysis (DTR) within NINDS, and in concert with other NIH-institutes, launched a series of translational applications to enhance neuroscience drug discovery and improvement efforts to mitigate the present pipeline gaps. These translational programs are milestones-driven cooperative agreements (The Blueprint Neurotherapeutics Network; Biotechnology Merchandise and Biologics; Small small business 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 VEGFR1/Flt-1 Accession Injuries) or screening applications which include Epilepsy Therapy Screening Plan and Preclinical Screening Platform for Pain. In this poster, we outline to neuroscientists in academia and industry the different NINDS/DTR-funding mechanisms and resources to help their drug discovery initiatives or ongoing preclinical and translational activities inside 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 illness (PD) is a gradually progressive and disabling neurodegenerative disorder affecting an estimated 7 to 10 million people worldwide. Despite recent advances in drug improvement, dopaminergic drugs such as L-DOPAASENT2021 Annual Meeting Abstractsremain today’s standard-of-care, in spite of the side-effects it really is inducing in the long-term. To gain in effectiveness, translational study requirements clinically relevant animal models of PD that show similar pathophysiological and functional traits than the ones identified in human individuals. The extensively adopted 6-OHDA rat model is one of them and expresses exactly the same aberrant EEG oscillatory patterns as these characterized inside the clinic, making the model very predictive for drug discovery. State-of-the-art clinical literature shows that motor symptoms of Parkinson’s illness result from a dysfunction with the cortico-basal ganglia circuits. A hyper synchronization of beta rhythms in this circuit, positively correlated to motor symptoms, has been characterized in each parkinsonian sufferers and animal models. This aberrant excessive beta oscillation is suppressed by dopaminergic remedies, and which enhance motor deficits at the same time. A chronic S1PR3 Source 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 from the antidyskinetic drug amantadine on L-DOPA low dose-induced gamma oscillations inside the 6-OHDA rat. Unilaterally 6-OHDA-lesioned rats have been implanted using a bipolar electrode inside the motor cortex ipsilateral of the lesion. On 1 hand, the acute impact of dopaminergic drugs was evaluated around the abnormal beta oscillation. Alternatively, 6-OHDA-lesioned rats were treated daily for two weeks with six mg/kg L-DOPA to induce stable gamma oscillations, which had been monitored at days 1, 5, eight, 12, and 15 working with EEG recordings. The effects of pre-treatments with either vehicle or amantadine (45 or 90 mg/kg) 120 min prior to L-DOPA injection was then evaluated on gamma oscillations and L-DOPA induced.
