On your MARCKS. Get set. Go


An important aspect of developing better remedies for Parkinson’s involves determining when and where the condition starts in the brain. What is the underlying mechanism that kicks things off and can it be therapeutically targetted?

Recently, researchers from Japan have suggested that a protein called Myristoylated alanine-rich C-kinase substrate (or simply MARCKS) may be a potentially important player in the very early stages of Parkinson’s (and other neurodegenerative conditions).

Specifically, they have found that MARCKS is present before many of the other pathological hallmarks of Parkinson’s (such as Lewy bodies) even appear. But what does this mean? And what can we do with this information?

In today’s post, we will look at what MARCKS is, what new research suggests, and how the research community are attempting to target this protein.

One of the most interesting people I met during my time doing Parkinson’s assessment clinics was an ex-fire forensic investigator.

We would generally start each PD assessment session with a “brief history” of life and employment – it is a nice ice breaker to the appointment, helped to relax the individual by focusing on a familiar topic, and it could provide an indication of potential issues to consider in the context of Parkinson’s – such as job related stress or exposure to other potential risk factors (eg. pesticides, etc).

But so fascinated was I with the past emplyoment of the ex-fire forensic investigator gentleman that the “brief history” was anything but brief.

We had a long conversation.

One aspect of fire forensics that particularly fascinated me was the way he could walk into a recently burned down property, and he could “read the story backwards” to identify the root cause of the fire.

He could start anywhere on a burnt out property and find his way back to the source (and also determine if the fire was accidental or deliberate).

I marvelled at this idea.

And I can remember wondering “why can’t we do that with Parkinson’s?

Well, recently some Japanese researchers have had a crack at “reading the story backwards” and they found something rather interesting.

What did they find?
