Too much LRRK2 begets too little GCase?

 

New research from multiple independent research groups proposes that one Parkinson’s associated protein (LRRK2) may be affecting the activity of another Parkinson’s associated protein (GCase).

Specifically, when LRRK2 becomes hyperactive (as is the situation in some cases of Parkinson’s), it causes is associated with a reduction in the amount of GCase activity.

In today’s post, we will discuss what LRRK2 and GCase both do, what the new research suggests, and how this news could influence efforts to treat Parkinson’s in the future.

For a long time, the Parkinson’s research community had a set of disconnected genetic risk factors – tiny errors in particular regions of DNA that were associated with an increased risk of developing Parkinson’s – but there seemed to be little in the way of common connections between them.

The researchers studied the biological pathways associated with these risk factors, trying to identify potential therapeutic angles as well as looking for connections between them.

The therapies are currently being clinically tested (Click here to read more about these), but the connections have taken a lot longer to find.

Recently one important connection has been identified by several research groups and it could have important implications for how Parkinson’s will be treated in the future.

What’s the connection?

Dream, struggle, create, Prevail

 

The recent documents filed with the U.S. Securities and Exchange Commission by the biotech firm Prevail Therapeutics provides interesting insight into the bold plans of this company which was only founded in 2017.

Even more recent news that the U.S. Food and Drug Administration (FDA) has accepted the company’s Investigational New Drug (IND) application for its lead experimental treatment – PR001 – suggests that this company is not wasting any time. 

PR001 is a gene therapy approach targeting GBA-associated Parkinson’s.

In today’s post, we will discuss what GBA-associated Parkinson’s is, how Prevail plans to treat this condition, and discuss what we know about PR001.

The title of this post comes is from a quote by Caterina Fake (co-founder of Flickr and Hunch (now part of Ebay)), but it seemed appropriate.

This post is all about dreaming big (curing Parkinson’s), the struggle to get the research right, and to create a biotech company: Prevail Therapeutics.

What is Prevail Therapeutics?

Prevail is a gene therapy biotech firm that was founded in 2017.

The company was founded by Dr Asa Abeliovich:

It was set up in a collaborative effort with The Silverstein Foundation for Parkinson’s with GBA (Click here to read a previous SoPD post about this organisation) and OrbiMed (a healthcare-dedicated investment firm).

A focus on GBA-Parkinson’s

This week the ‘Michael J. Fox Foundation for Parkinson’s Research’ and ‘The Silverstein Foundation for Parkinson’s with GBA’ announced that they are collaboratively awarding nearly US$3 million in research grants to fund studies investigating an enzyme called beta glucocerebrosidase (or GCase).

Why is this enzyme important to Parkinson’s?

In today’s post, we will discuss what GCase does, how it is associated with Parkinson’s, and review what some of these projects will be exploring.

This is Jonathan Silverstein.

He is a General Partner 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 – at just 49 years of age – Jonathan was diagnosed with Parkinson’s.

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 for Parkinson’s with GBA.

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

This week, the Silverstein foundation and the Michael J. Fox Foundation for Parkinson’s Research made a big anoouncement.

The two organisations announced nearly US$3 million in grants to fund studies investigating an enzyme called glucocerebrosidase beta acid (or GCase).

And what exactly is glucocerebrosidase?

Happy birthday: Silverstein Foundation

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.

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).

When GCase is away, the GSLs will play

 

 

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?
