Two birds, one stone?

This week interesting research was published in the journal EMBO that looked at the Parkinson’s-associated protein Leucine-rich repeat kinase 2 (or LRRK2).

In their study, the researchers discovered that lowering levels of LRRK2 protein (in cells and animals) affected the ability of Mycobacterium tuberculosis – the bacteria that causes Tuberculosis – to replicate.

In today’s post, we will discuss what Tuberculosis is, how it relates to LRRK2 and Parkinson’s, and we will consider why this is potentially REALLY big news for Parkinson’s.

In Greek Mythology, there is the tale of Daedalus and Icarus.

Daedalus was a really smart guy, who designed the labyrinth on Crete, which housed the Minotaur (the ‘part man, part bull’ beast). For all his hard work, however, Daedalus was shut up in a tower and held captive by King Minos to stop the knowledge of his Labyrinth from spreading to the general public.

But a mere tower was never going to stop Daedalus, and he set about fabricating wings for himself and his young son Icarus (who was also a captive).

Being stuck in the tower limited Daedalus’ access to feathers for making those wings, except of course for the large birds of prey that circled the tower awaiting the demise of Daedalus and his son. But he devised a clever way of throwing stones at the birds in such a way, that he is able to strike one bird and then the ricochet would hit a second bird.

And thus, the phase ‘killing two birds with one stone’ was born (or so it is said – there is also a Chinese origin for the phrase – Source).

Interesting. And this relates to Parkinson’s how?!?

Well, this week researchers in the UK have discovered that a protein associated with Parkinson’s is apparently also associated with another condition: Tuberculosis. And they also found that treatments being designed to target this protein in Parkinson’s, could also be used to fight Tuberculosis.

Two birds, one stone.

What is Tuberculosis?

2017 – Year in Review: A good vintage

At the end of each year, it is a useful practise to review the triumphs (and failures) of the past 12 months. It is an exercise of putting everything into perspective. 

2017 has been an incredible year for Parkinson’s research.

And while I appreciate that statements like that will not bring much comfort to those living with the condition, it is still important to consider and appreciate what has been achieved over the last 12 months.

In this post, we will try to provide a summary of the Parkinson’s-related research that has taken place in 2017 (Be warned: this is a VERY long post!)


The number of research reports and clinical trial studies per year since 1817

As everyone in the Parkinson’s community is aware, in 2017 we were observing the 200th anniversary of the first description of the condition by James Parkinson (1817). But what a lot of people fail to appreciate is how little research was actually done on the condition during the first 180 years of that period.

The graphs above highlight the number of Parkinson’s-related research reports published (top graph) and the number of clinical study reports published (bottom graph) during each of the last 200 years (according to the online research search engine Pubmed – as determined by searching for the term “Parkinson’s“).

PLEASE NOTE, however, that of the approximately 97,000 “Parkinson’s“-related research reports published during the last 200 years, just under 74,000 of them have been published in the last 20 years.

That means that 3/4 of all the published research on Parkinson’s has been conducted in just the last 2 decades.

And a huge chunk of that (almost 10% – 7321 publications) has been done in 2017 only.

So what happened in 2017? Continue reading
