A thesis on a neuroprosthesis

~ Simon ~ 4 Comments

# # # #

While disease modifying therapies are the ultimate goal for better treating Parkinson’s, research into therapeutic approaches that can provide better quality of life of people living with the condition are equally important.

Neuroprosthetics are devices that use electrodes to interface with the nervous system and aim to restore function that has been lost. Cochlear implants are a good example of a neuroprosthetic that is improving people’s hearing.

Recently, researchers in Switzerland have presented initial findings for a spinal cord neuroprosthesis that can help alleviate the locomotor deficits experienced in Parkinson’s.

In today’s post, we will review the recent research and discuss what it could mean for the future of Parkinson’s treatment.

The experts will tell you that the “Cairo toe” is special because it is flexible.

That is to say, it physically bends.

And this ‘bending’ property makes it rather unique among ancient prosthetics.

You see, when it was constructed (between 2,700 and 3,000 years ago), most artificial limbs were only cosmetic, rather than functional. And this difference is made particularly clear when one compares the “Cairo toe” with other early prosthetics of the same age that do not bend (Source):

So for its time, the “Cairo toe” must have been positively state of the art technology. It was one of the first functional prosthetics.

Great, but what does this have to do with Parkinson’s???

Well, we have come a long way since the “Cairo toe” with prosthetics, and recently researchers have been exploring a new kind of functional prosthetic – an implant – with the goal of improving quality of life for people with Parkinson’s.

What do you mean?

5 years at Cure Parkinson’s

~ Simon ~ 5 Comments

# # # #

In October 2018, the author of this blog left academia and joined the medical research charity “Cure Parkinson’s“. It was a tiny organisation focused on disease modification in Parkinson’s, and I was really excited by the opportunity.

Cure Parkinson’s is widely seen as punching well above its weight in terms of impact (there were only 18 members of staff when I joined) and relentless in their efforts to bring novel therapies forward for the Parkinson’s community. I was flattered by the invitation to join the team.

The last 5 years has been one of the busiest and most stimulating periods of my life. And I have absolutely no regrets with the decision I made. In today’s post, I will provide some observations and learnings from my experience over the last 5 years and discuss how the field of Parkinson’s research has changed.

Doesn’t time fly.

I was surprised recently when I received an email alert from LinkedIn. I very rarely use the service, but the message informed me that I have been with my current employer for five years now.

I scratched my head and thought, ‘no, that’s not possible‘.

But actually, yes it’s very possible (that whole COVID-related period of time really warped reality didn’t it?).

In October 2018, I finished up my post-doctoral research position at the University of Cambridge and joined the medical research charity Cure Parkinson’s as their deputy director of research.

The decision began in 2017 when I met Dr Richard Wyse, the director of research at the charity.

Cure Parkinson’s Autumn Research Update meeting – 2023

~ Simon ~ 5 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 ~ 6 Comments

# # # #

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”?
