A preamble for prebiotics

~ Simon ~ 8 Comments

# # # #

For a long time it has been known that the microorganisms in our intestinal system play an important role in our overall health and wellbeing. 

Recently, researchers have been exploring how these tiny creatures and entities may be influencing Parkinson’s, and whether manipulation of them may impact the progression of the disease.

In today’s post, we will review a new pilot clinical study that investigated the effects of a prebiotic fiber intervention in a group of people with Parkinson’s.

You should never feel alone, because you most definitely are not.

I do not wish to alarm you, but there is approximately 2kg (4.4 pounds) of microorganisms in your gut.

And to put that into context, the “microbiota” of the gut is actually heavier by weight than your brain (1.5kg – 3.3 pounds).

What does “the microbiota” mean?

The microbiota refers to microorganisms that colonise various defined parts of the body (such as our skin or gastrointestinal tract). The human microbiota consists of the 10-100 trillion symbiotic microbial cells harbored by each person. By mass, the microbiota of the human body make up about 1 to 3 percent of our overall weight (weighing approximately two to three kilograms in an adult – Source). Collectively, it is one of our heaviest organs.

And whether you like it or not, you definitely need these little passengers. They serve a wide variety of necessary functions.

The microorganisms in the human gut, for example, perform all manner of tasks for you to make your life easier. From helping to break down food, to aiding with the production of certain vitamins (in particular B and K) that you do not make yourself.

So, as I said, you are never alone. And please remember that you are responsible for more than just yourself.

And the microbiota should not be confused with the microbiome, which refers to the collection of different genomes (DNA) from all the microorganisms in these microbiota.

Ok, understood. What do they have do with Parkinson’s?

Just a lysosomal enzyme…

~ Simon ~ 1 Comment

# # # #

About 5% of individuals affected by Parkinson’s carry a genetic variation in a region of their DNA called the GBA1 gene.

This area of DNA provides the instructions for making an enzyme called GCase, which is known to be involved in cellular waste disposal.

Recently, however, researchers have discovered that GCase might have additional functions in cells, particularly in the mitochondria.

In today’s post, we will discuss what GCase is, how it is associated with Parkinson’s, and review the new research indicating other roles in cellular biology.

Isn’t it funny how things change.

And I mean, properly change.

Something will start off in life as one thing, and then a new perspective or a conflicting idea is provided and suddenly it becomes something else entirely – changing how we view that thing and its place in the world.

A truly exaggerated example of this is the wonderous story of Adam Rainer.

Born in Austria (1899), Adam was always a small child and by the time he reached 18 years of age he measured just 138 cm (or 4 foot 5 inches). Due to his height, he was technically considered a dwarf (less than 147 cm or 4 foot 10 inches). As result of this designation, he was refused entry into the Austro-Hungarian Army and thus missed out on serving in the First World War.

But then something really strange happened…

From 21 years of age to 32, while everyone else stopped growing, Adam suddenly started to grow.

And when I say grow, I mean grow!

By the time Adam was 32, he had grown to the height of 218 cm (or 7 foot 2 inches). At that time, a benign tumor (a pituitary adenoma) was discovered and removed, slowing Adam’s growth. He died in 1950 at the age of 51, having reached a final height of 234 cm (7 foot 8 inches).

He is the only person in recorded history who started out in life with dwarfism and end it with gigantism (source).

Like I said, a rather exaggerated form of how something can change.

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

Being ABL to make a strong case for Inhibikase

~ Simon ~ Leave a comment

# # # #

At the Society for Neuroscience annual meeting in October 2015, the results of a small phase 1 clinical study were presented and the Parkinson’s community got rather excited by what they saw.

The study had investigated a cancer drug called ‘nilotinib’ (also known as Tasigna) on 12 people with advanced Parkinson’s or Dementia with Lewy bodies. After 6 months of treatment, the participants reported that they were functioning better on nilotinib.

Two larger, more carefully controlled phase 2 clinical trials of nilotinib in people with Parkinson’s were conducted, and both studies could not replicate the original findings (worse: the drug was barely detected in the brain). But now a biotech company called Inhibikase has developed a nilotinib-like agent that can access the brain and they are clinically testing it. This week they published preclinical data on their lead agent, IkT-148009.

In today’s post, we will look at the history of this story, review the recently published preclinical research from Inhibikase, and discuss the current clinical trial.

Cancer.

There’s a happy topic to start a post with.

Cancer is a condition where cells in a specific part of the body start to grow and reproduce uncontrollably. There are lots of different types of cancers, but I would like to draw your attention to one in particular: Leukemia 

Leukemia is a particular branch of cancer. It is a broad term used for cancers of the body’s blood-forming tissues (these include the bone marrow and the lymphatic system).

The type of leukemia diagnosed depends entirely on the type of blood cell that becomes cancerous and on whether it grows quickly or slowly. Leukemia occurs most often in adults older than 55, but it is also the most common cancer in children younger than 15.

There are approximately 10,000 new cases of leukemia (that’s 27 every day), and ~5000 deaths associated with the condition in the UK (Click here for the source of these figures).

Interesting, but why are you starting this post by talking about leukemia?

The “What would I do” post? Part 3

~ Simon ~ 1 Comment

# # # #

Given the broad range of topics covered on the SoPD, I am very regularly asked “what would you do if you were diagnosed with Parkinson’s tomorrow?”

As a research scientist I am not comfortable answering this question, but I can see how it is a fair one to ask. I have previously attempted to address it (Click here and here to read those posts), and I point folks who do ask in the direction of those posts.

And as new research and more tools become available, I can see some value in revisiting this question.

So in today’s post, we will do the 2023 version of “what would I do if I were diagnosed with Parkinson’s tomorrow?”.

Before starting, I would just like to thank readers for their kind words of support regarding my personal situation (see this previous post to understand what I am talking about).

My ward is now in full time care. But the guardianship order is still not in place which makes things rather problematic.

Source: EducationLawyers

The UK deputyship system seems to have become glacial in its process. I was advised that it would take 4-6 months, but we are now almost 12 months into the wait… and the care home bills are piling up very quickly. The resources to pay the bills are available, but without the deputyship being in place I am powerless to do anything about it.

Very frustrating. And certainly preventable.

And this is probably a good place to start this particular post.

What do you mean?

Year in review: 2022

~ Simon ~ 3 Comments

# # # #

At the end of each year, it is a useful process to take stock and review what we have learnt over the last 12 months.

2022 has been an extremely busy year for Parkinson’s research, with a lot of clinical trial results and new insights. As the world continues to re-open from the COVID-19 pandemic, there has been a continually rising tide of new research results and interesting new developments.

In today’s post, we will consider three big Parkinson’s-related research takeaways of 2022 (based on our humble opinions here at the SoPD), and then we will provide an extended overview of some of the important pieces of news from the last 12 months (Be warned: this will be a rather long post).

Hughe Knatchbull-Hugessen, the British Ambassador to China between 1936-1937 wrote in his memoir that before he left England for China, a friend told him of a Chinese curse, “May you live in interesting times” (Source).

I never really understood why this quote was considered “a curse”. Surely living in boring times would be more tortuous.

But the noise and chaos of recent years have really hammered home the nature of this curse. There were many days this year where I was wishing for less interesting times.

2022. Source: Wikipedia

That said, 2022 has been a fascinating experience. The full spectrum of human emotions has been elicited: From the highs of the football world cup to the horrors and catastrophic consequences of Russia’s ignominious invasion of Ukraine.

From the glorious achievements (such as the James Webb space telescope and a net energy gain from a fusion reaction), to the unfathomable idiocies of the UK and US political class (seriously, in the UK we had 3 prime ministers, 4 chancellors, and one gut wrenching “mini budget” disaster that showed the true fragility of our underfunded pension schemes) – 2022 had it all.

There were also an amazing array of new discoveries and insights in Parkinson’s research. And while such a statement may not bring much solace to those living with condition, it is tremendously encouraging to see the furious rate at which these findings are announced.

In this, the last SoPD post of 2022, we will look back and review the last 12 months by providing an overview of those pieces of research news that we here at SoPD HQ thought were most interesting. We apologise to any researchers who do not get a mention here (by all means feel free to berate us in the comments section below if you think we missed something key), but these were the announcements that really grabbed our attention.

Getting serious about saunas

~ Simon ~ 4 Comments

# # # #

In 2017, researchers reported that regular episodes in a sauna can dramatically reduce one’s risk of developing neurodegenerative conditions, like Alzheimer’s and Parkinson’s.

Recently, a member of the Parkinson’s community shared another feature of “sauna life” that helps them: they sleep better after a short sauna session right before bed.

In today’s post, we will discuss some of the research associated with the use of saunas.

# # # #

Source: Twitter

Fun fact: Finland has over 3 million saunas.

It is a rather impressive number considering that there is only 5.5 million people in the country. So important to the Finnish culture is the humble sauna that Unesco recently registered the sauna on its list of Intangible Cultural Heritage.

You will find a sauna at every public swimming pool, most hotels, private residence, and summer homes by the lake or the sea in Finland.

They are everywhere.

Just as the sport of rugby is central to everything in New Zealand (seriously, it’s like a religion), sauna life is an important corner stone of Finnish society. They love it.

Does this actually have anything to do with Parkinson’s?
