Dr. Jonathan Sackner-Bernstein
MD, PhD, FRCPE

Sackner-Bernstein conducted the first study to estimate the amount of dopamine free in the cytosol of the dopaminergic neurons in people with Parkinson’s. While confirming that tissue levels of dopamine are markedly reduced, statistical adjustments for the loss of neurons, axons and intracellular vesicles demonstrated that free dopamine levels trended higher in the caudate and were significantly elevated in the putamen. In parallel, multiple preclinical studies showed that the use of a drug to reduce dopamine improved biology and function. The data suggest that the neurons that drive Parkinson’s experience the disease as a state of dopamine excess, not deficiency, relevant because of the potential for dopamine’s breakdown products causing neuronal toxicity. Sackner-Bernstein launched a company to test such a drug treatment strategy in PD.

“Why I am optimistic that we might have a Silver Bullet for PD” – update by Dr. Sackner-Bernstein – UPDATE
Jonathan Sackner-Bernstein is aiming to transform the treatment of Parkinson’s Disease (PD). First, he discovered that the brain cells (dopaminergic neurons) in Parkinson’s patients are exposed to excess dopamine, reaching toxic levels. Next, he identified a drug that reverses disease pathology by reducing dopamine levels in 10 studies using laboratory models of PD. Today’s session focuses on Dr. Sackner-Bernstein’s most recent progress.
