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?
