Cure Parkinson’s Autumn Research Update meeting – 2023

~ Simon ~ 2 Comments

# # # #

Cure Parkinson’s is a medical research charity that is focused on disease modification for Parkinson’s. Our only goal is to slow, stop or reverse the condition. To achieve this aim, we fund and support preclinical projects (that are with 5 years of clinical testing) and clinical trials focused on testing new disease modifying therapies.

Twice a year we hold public events, where we share how the research we support is developing and progressing. It is an in-person event held in London, and we stream it live to the virtual audience who are unable to attend.

In today’s post, we will review the highlights of Cure Parkinson’s 2023 Autumn Research Update meeting.

# # # #

As long time readers will be aware, the freakishly tall, ridiculously good looking author of this blog is an employee of the medical research charity, Cure Parkinson’s.

He tries to be transparent about this and where Cure Parkinson’s is involved in the research being discussed on the SoPD website, he always indicates their involvement. He doesn’t want to be seen to be biasing the content here on the SoPD towards the charity’s activities, rather he prefers to take a broader view of all the interesting research that is going on in the Parkinson’s research world.

But, when there is Cure Parkinson’s related material that he thinks might be of interest to the wider Parkinson’s community, he is comfortable with highlighting it.

And today’s post is an example of this.

Recently, Cure Parkinson’s held their 2023 Autumn Research Update meeting at the Royal Society of Medicine in London:

DOPA de-car-box-yl-ase

~ Simon ~ 1 Comment

# # # #

Parkinson’s is a neurodegenerative condition that is diagnosed and monitored based on clinical observations and scoring systems – both of which are not perfect and subjective.

Biomarkers (a biological molecule found in bodily fluids or tissues that is an indicator of a normal or abnormal processes) represent an important development for medicine as they provide assurance and quantitative measures of disease, aiding the diagnostic and treatment process.

Recently there has been a lot of new research highlighting possible biomarkers for Parkinson’s, including proteins associated with the synthesis of dopamine (a chemical which is severely reduced in the brains of people with Parkinson’s).

In today’s post, we will discuss what a biomarker is and review some new research on a potential biomarker for ‘Lewy body disease’.

2023 is quickly becoming the year of potential biomarkers for Parkinson’s. There has been a lot of new research in this space.

For example, earlier this year, the Michael J Fox Foundation and collaborators reported new data regarding the alpha synuclein seeding assay (Click here to read a previous SoPD post on this topic).

Tests that can clearly define and track medical conditions over time are critical to developing better treatments and would certainly be invaluable in Parkinson’s research.

And this week we saw researchers publish further data, highlighting another potential biomarker.

What did they report?

Manifesting non-manifesting carriers

~ Simon ~ Leave a comment

# # # #

The discovery of genetic risk factors for Parkinson’s has been very useful for the research community as they point towards associated biological pathways that could potentially be targeted for therapeutic intervention.

They also represent a topic of concern for the Parkinson’s community, who worry about passing on possible risk to their children and subsequent generations. The penetrance (which refers to the proportion of people with a particular genetic variant who ever actually exhibit signs and symptoms of a particular condition) of many of these risk factors has, however, been found to be mixed, which has helped to confuse the matter. 

Recently, researchers have been exploring assays and biomarkers related to some of these genetic risk factors to see if we can determine who is likely to go on and develop Parkinson’s compared to “non-manifesting carriers” of the genetic risk factors. 

In today’s post, we will discuss what is meant by terms like “penetrance” and “non-manifesting carriers”, and we will review some of the latest research in this area.

This year represents the 25th anniversary since the discovery that tiny variations in a region of DNA called the “PARKIN gene” may increase the risk of developing Parkinson’s.

On the 9th April, 1998, this report was published in the journal Nature:

Title: Mutations in the parkin gene cause autosomal recessive juvenile parkinsonism.
Authors: Kitada T, Asakawa S, Hattori N, Matsumine H, Yamamura Y, Minoshima S, Yokochi M, Mizuno Y, Shimizu N
Journal: Nature. 1998 Apr 9; 392(6676):605-8
PMID: 9560156

This study highlighted 5 cases of ‘juvenile’ Parkinsonism from three unrelated Japanese families, in which genetic variations were found in the PARKIN gene. This finding came less than a year after the first genetic risk factor for Parkinson’s – in the alpha synuclein gene – had been announced (Click here to read a SoPD post about this).

It was an exciting time for Parkinson’s research as these new risk factors were pointing towards particular biological pathways that could be explored in the context of Parkinson’s (and manipulated for potentially therapeutic purposes).

Over the next 10-15 years, there was a genetic gold rush as researchers identified over 80 regions of DNA in which genetic variations (tiny alterations in the G,A,T & C coding) that increased one’s risk of developing PD (Click here to read a SoPD post on this topic).

But rather than being a genetic disease (a condition driven by a specific genetic cause), it quickly became apparent that the level of penetrance in Parkinson’s was not 100%, and questions started to be asked as to why.

What do you mean by “penetrance”?

The UP Study results

~ Simon ~ 2 Comments

# # # #

Preclinical data have suggested that the bile acid Ursodeoxycholic acid (or UDCA) has neuroprotective properties in models of Parkinson’s.

Researchers in Sheffield have led much of this research and they have also been coordinating a clinical trial assessing this molecule in people with Parkinson’s.

The study was called the “UDCA in Parkinson’s” trial (or UP Study) and the results were recently published.

In today’s post, we will explore the history of UDCA research, review the results of the UP study, and discuss what could happen next.

Every good lab bench-to-clinical trial story starts somewhere.

There is an initiating moment, which is probably irrelevant to most of the people present at the time, but it becomes life-defining for others. In the case of today’s post, that moment occurred while Prof Heather Mortiboys was was sitting in a lecture during the last year of her undergraduate degree in University.

The lecturer said that although our knowledge and understanding of what happens in Parkinson’s has increased significantly, there are still no treatments to prevent or slow the condition.

Heather couldn’t understand this.

She wondered how much more knowledge could be gained without actually identifying new treatments? And from that moment onwards she has pursued a research career in Parkinson’s research (and we are lucky for it!).

After receiving her PhD in Neuroscience (summa cum laude) from the International Max Planck Institute in Dresden (Germany), she moved to the Neuroscience department at the University of Sheffield in 2006 to work with Prof Oliver Bandmann.

And in 2013, they published the results of a large screening study that identified a very interesting molecule.

This was the research report in question:

Title: Ursocholanic acid rescues mitochondrial function in common forms of familial Parkinson’s disease
Authors: Mortiboys H, Aasly J, Bandmann O.
Journal: Brain. 2013 Oct;136(Pt 10):3038-50.
PMID: 24000005
