“What’s the evolutionary advantage of Parkinson’s?”

~ Simon ~ 24 Comments

Each year King’s College London holds the Edmond J. Safra Memorial Lecture. It is a public event – exploring cutting-edge research on Parkinson’s – held in honour of the late philanthropist and financier, Mr Edmond J Safra, .

I was lucky enough to attend this year’s event (entitled A vision of tomorrow: How can technology improve diagnosis and treatment for Parkinson’s patients?). It highlighted the fantastic research being carried out by Professor Marios Politis and his team.

During the Q&A session of the event though, a question was asked from the audience regarding what the evolutionary advantage of Parkinson’s might be. The question drew a polite chuckle from the audience.

But the question wasn’t actually as silly as some might think.

In today’s post we look at some evidence suggesting an evolutionary advantage involving Parkinson’s.

Despite the impressive name, King’s College London is not one of the grand old universities of England.

Named after its patron King George IV (1762-1830), the university was only founded in 1829 (compare this with 1096 for Oxford and 1209 for Cambridge; even silly little universities like Harvard date back further – 1636). The university is spread over five separate campuses, geographically spread across London. But if you ever get the chance to visit the main Strand campus, ask for the chapel and take a moment to have a look – it is very impressive (the image above really doesn’t do it justice).

As I mentioned in the intro, each year King’s College London holds the Edmond J. Safra Memorial Lecture. It is an event that is open to the public and it involves a discussion regarding innovative new research on Parkinson’s. The evening is held in honour of the late Mr Edmond J Safra.

This year, Professor Marios Politis and members of his research group were presenting lectures on “How can technology improve diagnosis and treatment for Parkinson’s”. The lectures were very interesting, but the reason I am writing about it here is because during the question and answer session at the end of the lectures, the following question was asked:

“What’s the evolutionary advantage of Parkinson’s?”

Given the debilitating features of the condition, the audience was naturally amused by the question. And there was most likely several people present who would have thought the idea of any evolutionary advantage to Parkinson’s a ridiculous concept.

But it’s not.

And there is actually research to suggest that something evolutionary could be happening with Parkinson’s.

?!?!? What do you mean?

The dilemma of success

~ Simon ~ 17 Comments

Late last year, I wrote a post for Parkinson’s UK‘s excellent blog on Medium.

My piece was called the Dilemma of Success, and it explored a hypothetical situation that we may very well face in the not-so-distant future.

Optimistic as I am about the future of Parkinson’s research, I think this is a very serious issue – one which the Parkinson’s community needs to discuss and start planning for. I am re-posting it here today as I am keen for some thoughts/discussion on this matter.

My scout master looked around the horse shoe, making eye contact with each of us, before asking a simple question:

“When did Noah build the ark?”

My fellow scouts and I looked at each other. Some of us were wondering if the guy had completely lost the plot and somehow thought that it was Sunday morning and he was doing the sermon. Others seriously looked like they were trying to calculate an exact date.

He waited a moment for one of us to offer up some idiotic attempt at an answer, before he solemnly said:

“Before the rain”

It’s one of those childhood moments that didn’t make sense at the time, but comes back to haunt you whenever you can foresee certain troubles coming over the hill towards you.

The dilemma of success

It will be nice to have this problem, but it will still be a problem.
And we need to plan for it

Happy birthday: Silverstein Foundation

~ Simon ~ 7 Comments

Over the last 12 months, the Silverstein Foundation has quickly established itself as a major focused force in the fight against Parkinson’s.

And when I say ‘focused’, I mean ‘focused’ –  the foundation is “actively pursues and invests in cutting edge research with the goal of discovering new therapies for the treatment of Parkinson’s Disease in glucocerebrosidase (GBA) mutation carriers”.

But the output of this effort may well have major benefits for the entire Parkinson’s community.

In today’s post, we will discuss what GBA is, how it functions inside cells, its association with Parkinson’s, and what all of this GBA focused research being funded by the Silverstein Foundation could mean for the Parkinson’s community.

This is Jonathan Silverstein.

He’s a dude.

He is also a General Partner and a Co-Head of Global Private Equity at OrbiMed – the world’s largest fully dedicated healthcare fund manager. During his time at OrbiMed, the company has invested in healthcare companies that have been involved with over 60 FDA approved products.

In February 2017, he was diagnosed with Parkinson’s disease at just 49 years of age.

Rather than simply accepting this diagnosis, however, Mr Silverstein decided to apply the skills that he has built over a long and successful career in funding biotech technology, and in March 2017, he and his wife, Natalie, set up the Silverstein Foundation.

They raised $6 million from donors and then provided another $10 million of their own money to fund the endeavour, which has funded a dozen research projects and started a new company called Prevail Therapeutics (we’ll come back to this shortly).

The foundation has just one mission: “to actively pursue and invest in cutting edge research with the goal of discovering new therapies for the treatment of Parkinson’s Disease in GBA mutation carriers”

And it seeks to address this by achieving three goals:

  1. to find a way to halt the progression of Parkinson’s with GBA.
  2. to identify regenerative approaches to replace the damaged/lost cells
  3. to find preventative measures

What is ‘GBA’?

One black sheep per week

~ Simon ~ 3 Comments

Each time a cell divides, the DNA inside the resulting pair of cells has changed slightly. These small alterations – known as genetic mutations – provide a method by which an organism can randomly determine traits that may be beneficial.

New research indicates that in certain parts of the brain, post-mitotic (non-dividing) cells are taking on as many as one mutation per week across the span of our lives. This results in thousands of genetic variations accumulating in each cell by the time we eventually pass away in old age.

In today’s post we will review new research and consider what this gradual build up of genetic mutations could mean for our understanding of neurodegenerative conditions, like Parkinson’s.

Coming from the back waters of third world New Zealand, you will understand that sheep hold a very special place in my heart.

I grew up a simple country lad, and each year I had a pet lamb that I would raise and train to do silly tricks in the hope of impressing the judges at the annual agricultural/farm day at school. In addition to instilling me with a crazy fanaticism for the sport (read: religion) of rugby, my parents figured that having a pet lamb each year would teach me a sense of responsibility and a sort of discipline.

I’m not really sure how this practice has influenced my later life, but I certainly do have very fond memories of those early years (the first lamb was named ‘Woolly’, the 2nd lamb was named ‘Woolly2’, the third lamb was actually a goat – bad lambing season – which I named ‘Billy the kid’, the 4th lamb was named ‘MacGyver’,…).

Lots of happy memories.

But as I grew into the teenage years, there was one thing that really bothered me with regards to my pet lambs.

It was that whole negative stigma associated with the ‘black sheep’.

Why, I would wonder, was it the ‘black sheep of the family’ that was the bad kid? And why was the one black sheep in every flock considered the worst of the bunch?

Why was this association applied to sheep?

Why not dogs? Or cows? Why do we pick on sheep?

When the zombies are all in your head

~ Simon ~ 5 Comments

In your brain there are different types of cells.

Firstly there are the neurons (the prima donnas that we believe do most of the communication of information). Next there are the microglia cells, which act as the first and main line of active immune defence in the brain. There are also oligodendrocyte, that wrap protective sheets around the branches of the neurons and help them to pass signals.

And then there are astrocytes.

These are the ‘helper cells’ which maintain a comfortable environment for the neurons and aid them in their task. Recently, researchers in California reported an curious observation in the Parkinsonian brain: some astrocytes have entered an altered ‘zombie’-like state. And this might not be such a good thing.

In today’s post, we’ll review the research and discuss what it could mean – if independently replicated – for the Parkinson’s community.

Zombies. Source: wallpapersbrowse

I don’t understand the current fascination with zombies.

There are books, movies, television shows, video games. All dealing with the popular idea of dead bodies wandering the Earth terrifying people. But why the fascination? Why does this idea have such appeal to a wide portion of the populous?

I just don’t get it.

Even more of a mystery, however, is where the modern idea of the ‘zombie’ actually came from originally.

You see, no one really knows.

Huh? What do you mean?

Some people believe that the word ‘zombie’ is derived from West African languages – ndzumbi means ‘corpse’ in the Mitsogo language of Gabon, and nzambi means the ‘spirit of a dead person’ in the Kongo language. But how did a word from the African continent become embedded in our psyche?

Others associate the idea of a zombie with Haitian slaves in the 1700s who believed that dying would let them return back to lan guinée (African Guinea) in a kind of afterlife. But apparently that freedom did not apply to situations of suicide. Rather, those who took their own life would be condemned to walk the Hispaniola plantations for eternity as an undead slave. Perhaps this was the starting point for the ‘zombie’.

More recently the word ‘zonbi’ (not a typo) appeared in the Louisiana Creole and the Haitian Creole and represented a person who is killed and was then brought to life without speech or free will.

Delightful stuff for the start of a post on Parkinson’s research, huh?

But we’re going somewhere with this.

Monthly Research Review – January 2018

~ Simon ~ 22 Comments

Today’s (experimental) post provides something new – an overview of some of the major bits of Parkinson’s-related research that were made available in January 2018.

In January of 2018, the world was rocked by news that New Zealand had become the 11th country in the world to put a rocket into orbit (no really, I’m serious. Not kidding here – Click here to read more). Firmly cementing their place in the rankings of world superpowers. In addition, they became only the second country to have a prime minister get pregnant during their term in office (in this case just 3 months into her term in office – Click here to read more about this).

In major research news, NASA and NOAA announced that 2017 was the hottest year on record globally (without an El Niño), and among the top three hottest years overall (Click here for more on this), and scientists in China reported in the journal Cell that they had created the first monkey clones, named Zhong Zhong and Hua Hua (Click here for that news)

‘Talking bout my resolution’

~ Simon ~ 27 Comments

As we have previously discussed, 2017 was a fantastic year for Parkinson’s research (Click here to read that post). And as we approach the end of January, it is already apparent that 2018 is likely to be as good if not better (Click here for an overview of what to expect from 2018).

The transition into a new year brings with it a period of reflection and resolutions. At the start of each year I usually have a post that asks for readers feedback regarding how the SoPD website could be improved.

This year is going to be slightly different.

In today’s post we will discuss some of the ideas that I have in mind for 2018 – any and all reader feedback would be greatly appreciated.

The title of today’s post is a play on words. It is a salute to the song ‘My generation’ by the rock band “The Who” (click on the image above to hear the song). The song was released as a single on the 29th October 1965. It reached No. 2 in the UK and No. 74 in America.

Despite never actually reaching No.1, Rolling Stone magazine still named ‘My generation’ the 11th greatest song of all time (Source). The British music magazine New Musical Express (NME), noted that the song “encapsulated the angst of being a teenager,” and was a “nod to the mod counterculture” (Source).

The Who‘s guitarist, Pete Townshend, apparently wrote “My Generation,” on his 20th birthday (19th May 19th, 1965), while riding a train from London to Southampton for a television appearance. He claims that it was never meant to be the battle cry for young mod rebels that it went on to become.

Rather it was intended to express Townshend’s fears about ‘the impending strictures of adult life’. He preferred to stay young, free and experimental.

I am not having any teenage angst issues or fearing the very current strictures of adult life. I am simply using a play of the song’s title here in order to discuss a new year’s resolution I have made regarding the SoPD website over the never 12 months.

Let me explain.

Inspiration from a church in Mammoth

~ Simon ~ 8 Comments

Last year at the Intel International Science and Engineering Fair, a young high school student named Jeremiah Pate (Image above) took first Place in his category and third prize overall in the Dudley R. Herschbach Stockholm International Youth Science Seminar Award.

This competition involved nearly seven million high school students from all over the world. And by being a winner in the competition, Jeremiah received an all expenses paid trip to attend the Nobel Prize Awards in Stockholm Sweden.

Jeremiah’s award winning project was about his efforts to find a possible cure for Parkinson’s.

In today’s post we will look at the interesting story of how Jeremiah became interested in Parkinson’s and discuss why impatience is a virtue.

We all like stories that involve something bold.

The moon-shot. The last stand against impossible odds. The underrated boxer beating the champ. The enthusiasts putting Gossamer satellites into space. Big-obstacle-being-overcome, that sort of stuff.

I personally really like those stories about individuals with a very specific goal and the determination to let nothing stand between them and achieving it. Those folks who are not satisfied with the status quo and want to change things for the better. Here at the SoPD, we have previously tried to highlight individuals like this within the Parkinson’s research community (for example, Dr Lysimachos Zografos and Sara (soon to be Dr) Riggare). And in keeping with that tradition, today’s post is about a similar individual.

His name is Jeremiah.

And the story begins at the First Baptist Church in Mammoth, Arizona.

EDITORIAL: That Pfizer news

~ Simon ~ 22 Comments

On Saturday 7th January, 2018, one of the world’s largest pharmaceutical companies – Pfizer – announced that it was abandoning research efforts focused on finding new drugs for Alzheimer’s and Parkinson’s. 

Naturally, the Parkinson’s and Alzheimer’s communities reacted with disappointment to the news, viewing it as a demoralising tragedy. And there was genuine concern that other pharmaceutical companies would follow suit in the wake of this decision.

Those fears, however, are unfounded.

In today’s post we will look at some of the reasons underlying Pfizer’s decision, why our approach to failure is wrong, why Pfizer will definitely be back, and what the Parkinson’s community can do about it all.

1. Our approach to failure

I am currently reading “Black box thinking: The Surprising Truth About Success“. It is a really interesting book by journalist Matthew Syed that investigates how we approach to failure.

In the first chapter of his book, Syed makes comparisons between the way the aviation industry and the medical profession approach failure, pointing out the processes that follow situations when a disasters occur. In the aviation industry, when any event occurs there is a major investigative process that starts with the recovery of the black boxes. The aviation industry uses this system of investigation to learn from every single incident. It makes the information available to all and this helps with re-thinking everything from cockpit ergonomics and design to air traffic controller procedures. Even the airline companies are keen to be seen to be involved in this process of investigation. Failure, while unfortunate, is not shameful or stigmatising, but rather embraced and enlightening. 

In addition, Syed points out that when an airline pilot sits down in his/her cockpit, their neck is also on the line if something goes wrong. Thus, it is in their best interest that the flight should be successful. And this is another reason why the aviation industry takes the reporting of failure so seriously. Everyone benefits from learning from previous situations. And all of this comes together with the observation that 2017 was the safest year on record for flying (based on deaths/flights – Source).

When GCase is away, the GSLs will play

~ Simon ~ 7 Comments

 

 

New research published in the last week provides further experimental support for numerous clinical trials currently being conducted, including one by the biotech company Sanofi Genzyme.

Researchers have demonstrated that tiny proteins which usually reside on the outer wall of cells could be playing an important role in the protein clustering (or aggregation) that characterises Parkinson’s. 

In today’s post we will look at this new research and discuss what it could mean for the on going clinical trials for Parkinson’s.

The proverb ‘When the cat is away, the mice will play’ has Latin origins.

Dum felis dormit, mus gaudet et exsi litantro (or ‘When the cat falls asleep, the mouse rejoices and leaps from the hole’)

It was also used in the early fourteenth century by the French: Ou chat na rat regne (‘Where there is no cat, the rat is king’).

And then Will Shakespeare used it in Henry the Fifth(1599), Act I, Scene II:

Westmoreland, speaking with King Henry V, Gloucester, Bedford, Exeter and Warwick
“But there’s a saying very old and true,
‘If that you will France win,
Then with Scotland first begin:’
For once the eagle England being in prey,
To her unguarded nest the weasel Scot
Comes sneaking and so sucks her princely eggs,
Playing the mouse in absence of the cat,
To tear and havoc more than she can eat”

The phrase first appears in its modern form in the United States in the literary and political magazine The Port folio in 1802 (2; 323):

Interesting. But what does any of this have to do with Parkinson’s?
