Research Description

The Molecular Neurobiology Laboratory at the MassGeneral Institute for Neurodegenerative Disease, under the direction of Michael Schwarzschild, MD PhD, investigates molecular mechanisms in mouse models of Parkinson’s disease in an effort to develop improved therapies for Parkinson’s and related neurodegenerative diseases. We focus on a natural class of compounds known as purines, in particular the role of three purines — adenosine, caffeine and urate — and how targeting them may prevent or slow the brain cell degeneration of Parkinson’s.

The lab is pursuing major epidemiological and clinical clues to the disease through fruitful inter-disciplinary collaborations with the research group of Professor Alberto Ascherio at the Harvard School of Public Health and with the Parkinson Study Group of North America. Caffeine and urate are linked to a lower risk of Parkinson’s and/or to a slower rate of disease progression in humans.

The lab explores how caffeine (and other blockers of the adenosine A2A receptor) and urate may be protecting brain cells in Parkinson’s. We employ complementary pharmacological and genetic (e.g., gene knockout) tools to dissect the role of adenosine and urate pathways in the brains of parkinsonian mice. We are also studying the role of adenosine receptors in the disabling motor complications (abnormal involuntary movements known as dyiskinesia) that are sometimes triggered by standard anti-parkinsonian therapy.

Through our well-established translational research network and track record, we expedite transfer of our molecular insights from the laboratory back to the clinic in order to maximize their impact on the lives of Parkinson’s disease patients.

Adenosine/Caffeine Project

Models of Neurodegeneration

Using models of neurodegeneration, this part of the project seeks to understand how adenosine A2A receptor antagonists, including caffeine, protect neurons in models of Parkinson’s disease.

Proposed mechanism of symptomatic anti-parkinsonian action of adenosine A2A antagonists

Models of Dyskinesia

Using models of dyskinesia this part of the project looks at how adenosine A2A receptor antagonists may prevent development of dyskinesias.

Urate Project

This project explores how genetic and pharmacological manipulation of the urate pathway may reduce neurodegeneration in models of Parkinson’s disease.

Gender differences in Parkinson’s disease

Drs. Anne B. Young, Ippolita Cantuti-Castelvetri and Michael Schwarzschild study gender differences in Parkinson’s disease from three different investigative approaches.

E Pluribus Unum for Parkinson Disease - Researchers Draw on Sources to Improve Treatment of PD

What do Gaucher’s disease, gout, and amyloid plaques have in common? For researchers at the MGH, each of them may shed light on the causes and treatment of Parkinson’s disease.
