Monoamine oxidase A (MAOA) is an enzyme located on the outer mitochondrial membrane that catalyzes the oxidative deamination of DA. Both α-SYN and MAOA are associated with PD pathogenesis,…
• The road ahead: 2020 January 5, 2020 Here at the SoPD, we are primarily interested in disease modification for Parkinson’s.

At the start of each year, it is a…

• Not dead, dormant dopamine neurons?!? January 18, 2020   Every textbook written about the condition will tell you that the classical pathological characteristic of Parkinson’s is the loss of dopamine neurons in the midbrain region of the brain. It is the distinguishing feature that pathologists look for in order to provide a postmortem diagnosis of the condition. But what is meant by the words ‘loss of dopamine neurons’?…
• PARP-kinson’s goes chlorogenic December 20, 2020 # # # # For a long time it was been reported that coffee may be able to reduce the risk of developing Parkinson’s, but the mechansim by which this association could be occurring has remained elusive. Now researchers from South Korea have discovered a biological pathway that could help to explain the protective association. It involves a protein called…
• Making a strong case for GCase November 25, 2019   Novel therapies are increasing being developed to focus on specific subtypes of Parkinson’s. The hope is that if they work on one type of Parkinson’s, then maybe they will also work on others. Many of these new experimental treatments are focused on specific genetic subtypes of the condition, which involve having a specific genetic variation that increases one’s risk…

There are several Parkinson’s genetic risk…
• Synucleinopathy begets channelopathy? March 20, 2021 # # # # Alpha synuclein is a protein that is closely associated with Parkinson’s. It was the first gene to be associated with increased risk of developing Parkinson’s, and the alpha synuclein protein was found to be present in Lewy bodies – a characteristic feature of the Parkinson’s brain. As a result of this association, researcher have used high…
• The Tau of LRRK2 December 3, 2019   Dense spherical clusters of a protein – called Lewy bodies – are one of the classical hallmarks of the Parkinsonian brain. They are a common pathological feature, but curiously they are not present in all cases of Parkinson’s. For example, some individuals with certain forms of Parkinson’s associated with specific genetic mutations do not exhibit any Lewy bodies. Variations…
