York: #Parkinsons2018

 

On the 12th and 13th November, Parkinson’s UK held their biennial research conference in York.

It is not only an opportunity for the charity to showcase some of the research that they have funded over the last few years, but it was also a chance for members of the Parkinson’s research community to come together to share ideas, network and form new collaborations.

I was lucky enough to attend the event this year, and wanted to share some of the take away messages from the conference with the readers.

In today’s post, we will review Parkinson’s UK 2018 research conference (#Parkinsons2018).

 


Parkinson’s UK is the largest Parkinson’s research and support charity in the United Kingdom. Since 2015, they have invested over £18 million in a variety of research projects focused on all aspects of Parkinson’s – from new experimental treatments to the Parkinson’s UK Brain Bank.

 

 

Every two years, Parkinson’s UK holds a conference highlighting some of the research that the organisation has funded over the last few years. The meeting is usually held in the beautiful walled city of York – lots of history and narrow streets to explore.

Green light in Kyoto

Parkinson’s is a neurodegenerative condition. This means that cells in the brain are being lost over time. Any ‘cure’ for Parkinson’s is going to require some form of cell replacement therapy – introducing new cells that can replace those that were lost.

Cell transplantation represents one approach to cell replacement therapy, and this week we learned that the Japanese regulatory authorities have given the green light for a new cell transplantation clinical trial to take place in Kyoto.

This new trial will involve cells derived from induced pluripotent stem cells (or IPS cells).

In today’s post we will discuss what induced pluripotent stem cells are, what previous research has been conducted on these cells, and what we know about the new trial.

The man in the image above is Prof Shinya Yamanaka.

He’s a rockstar in the biomedical research community.

Prof Yamanaka is the director of Center for induced Pluripotent Stem Cell Research and Application (CiRA); and a professor at the Institute for Frontier Medical Sciences at Kyoto University.

But more importantly, in 2006 he published a research report that would quite literally ‘change everything’.

In that report, he demonstrated a method by which someone could take a simple skin cell (called a fibroblast), grow it in cell culture for a while, and then re-program it so that it would transform into a stem cell – a cell that is capable of becoming any kind of cell in the body.

The transformed cells were called induced pluripotent stem (IPS) cell – ‘pluripotent’ meaning capable of any fate.

It was an amazing feat that made the hypothetical idea of ‘personalised medicine’ suddenly very possible – take skin cells from anyone with a particular medical condition, turn them into whatever cell type you like, and then either test drugs on those cells or transplant them back into their body (replacing the cells that have been lost due to the medical condition).

IPS cells are now being used all over the world, for all kinds of biomedical research. And many research groups are rushing to bring IPS cell-based therapies to the clinic in the hope of providing the long sort-after dream of personalised medicine.

This week the Parkinson’s community received word that the Pharmaceuticals and Medical Devices Agency (PMDA) – the Japanese regulatory agency that oversees clinical trials – have agreed for researchers at Kyoto University to conduct a cell transplantation trial for Parkinson’s, using dopamine neurons derived from IPS cells. And the researchers are planning to begin their study in the next month.

In today’s post we are going to discuss this exciting development, but we should probably  start at the beginning with the obvious question:

What exactly is an IPS cell?

The Chinese stem cell trial

Chinese researchers recently published pre-clinical research demonstrating the use of their protocol for generating stem cell-derived neurons for cell transplantation in Parkinson’s.

The data represents the last step/proof-of-principle stage for taking this procedure into clinical trials (which are ongoing).

In today’s post, we will discuss what cell transplantation is, we will review the new data, and we will consider some of the issues associated with taking this procedure to the clinic.

As we have discussed before, any ‘cure’ for Parkinson’s requires 3 components:

  1. A disease halting mechanism – slowing or stopping the progression of the condition
  2. A neuroprotective agent – a treatment that will protect and support the remaining cells
  3. Some form of cell replacement therapy – introducing new cells to replace the ones that have been lost

Now, the bad new is that there is no ‘silver bullet’ on the horizon that provides all three (for example, there is no neuroprotective agent that also replaces lost cells).

But the good news is that we have a great deal of clinical research being conducted in all three of these areas. This video provides an overview of just some of the many different ways we are approaching all three components:

Recently a research report focused on a cell transplantation (a form of cell replacement therapy) approach for Parkinson’s was published by a group of researchers in China. They have proposed that the results presented in the report justify their efforts to take this approach forward into clinical testing.

What is cell transplantation?

The road ahead: Parkinson’s research in 2018

The great ice hockey player Wayne Gretzky once said “A good hockey player plays where the puck is. A great hockey player plays where the puck is going to be” (the original quote actually came from his father, Walter). 

At the start of each year, it is a useful practise to layout what is planned for the next 12 months. This can help us better anticipate where ‘the puck’ will be, and allow us to prepare for things further ahead.

2017 was an incredible year for Parkinson’s research, and there is a lot already in place to suggest that 2018 is going to be just as good (if not better).

In this post, we will lay out what we can expect over the next 12 months with regards to the Parkinson’s-related clinical trials research of new therapies.

Many readers will be familiar with the name Warren Buffett.

The charming, folksy “Oracle of Omaha” is one of the wealthiest men in the world. And he is well known for his witticisms about investing, business and life in general.

He regularly provides great one liners like:

“We look for three things [in good business leaders]: intelligence, energy, and integrity. If they don’t have the latter, then you should hope they don’t have the first two either. If someone doesn’t have integrity, then you want them to be dumb and lazy”

“Work for an organisation of people you admire, because it will turn you on. I always worry about people who say, ‘I’m going to do this for ten years; and if I really don’t like it very much, then I’ll do something else….’ That’s a little like saving up sex for your old age. Not a very good idea”

“Choosing your heroes is very important. Associate well, marry up and hope you find someone who doesn’t mind marrying down. It was a huge help to me”

Mr Buffett is wise and a very likeable chap.

Few people, however, are familiar with his business partner, Charlie Munger. And Charlie is my favourite of the pair.
