Inflammation is the means by which tissue in our bodies communicate with the immune system to indicate when something is wrong. Tiny messenger proteins are released from stressed or damaged cells to alert neighbouring cells of their situation.
Ailing cells can also release additional components – such as DNA – that can activate immune cells and cause inflamation.
Recently, researchers have identified both messenger proteins and specific types of DNA that are present in the blood of individuals with a genetically-associated sub-type of Parkinson’s. The discovery could provide both novel biomarkers, but also point towards specific biological pathways that could be therapeutically targetted.
In today’s post, we will review this new research.

When cells in your body are stressed, damaged, or sick, they begin to release large amounts of tiny messenger proteins which inform the rest of your body that something is wrong.
When enough of these messenger proteins are released, cells of the immune system will become activated, and come looking for the source of the trouble.
This is inflammation.
Inflammation is a critical part of the immune system’s response to problems. It is the body’s way of communicating with the immune system and explaining that something is wrong. This also aid in activating the immune system so that it can help deal with the situation.
By releasing the messenger proteins (called cytokines), injured/sick cells kick off a process that results in multiple types of immune cells entering the troubled area of the body and undertaking very specific tasks.

The strength of the immune response depends on the volume of the signal arising from those released messenger proteins.
For a long time, it has been hoped that some of these messenger proteins might be useful as biomarkers for conditions like Parkinson’s. And recently, researchers have published data suggesting that they might have found one cytokine that could be very useful for a specific sub-set of people with Parkinson’s.
What did they find?

Canadian scientists recently reported that mice with a specific genetic variation – in the Parkinson’s-associated LRRK2 gene – differ in how they are able to deal with bacterial and viral infections.
Curiously, mice with the Parkinson’s-associated LRRK2 mutation could handle a bacterial infection better than normal mice, while mice with no LRRK2 protein struggled against the infection. And the researchers found that this effect was most prominent in female mice in particular.
And curiously, when the mice are infected with a dangerous virus, female mice with the Parkinson’s-associated LRRK2 mutation fared worse than their male counterparts.
In today’s post, we will discuss what LRRK2 is, review the new research, and explore what the sex difference could mean in terms of Parkinson’s.

I am a big fan of Autumn.
The colours and the crisp/bracing air. I love the long, slow afternoon strolls and anticipation of the festive season to come.
But most of all I love the license to eat all the good wintery food. After a summer of salads and light food, there is nothing better that entering a warm cottage or pub, and smelling the hearty food (my wife if French – we navigate based on the quality of eateries).

But there is a down side to autumn: The start of the flu season.
Luckily, our immune systems are pretty robust – doing battle on a moment-to-moment basis with all manner of pathogenic agents.
Recently, some Canadian scientists discovered something interesing about the immune system and it relates to Parkinson’s.

Researchers have recently described a new method to quantify a person’s “immune age” – a measure that could act as a key determinant of future health, as well as response to disease and treatment.
This novel test appears to provide a more reliable predictor for the status of one’s immune system than any other previous method.
And it could be useful in other ways.
In today’s post, we will discuss this new method of determining “immune age”, explore examples of how similar analysis has been used for other conditions, and consider what it could mean for Parkinson’s.
Do you remember Andre Agassi?
I know he’s still around, but when I was young and less beautiful, I was a big fan. Not only of his on court achievements, but also of his charismatic off-court image.
And it certainly paid off well for him:
One of the things that Agassi taught us was that “image is everything”.
Before Agassi, tennis was a conservative sport of white shirts & shorts (McEnroe was basically as radical as things got). It was bland, conservative, and – yes, I’ll say it – boring.
Agassi not only brought colour but charisma to the game. It was shocking and disgraceful to some, but to young, naive fools like me, it was a captivating breath of much needed fresh air.
Despite the early infatuation with the stylings of Mr Agassi, I have to admit that I have never remotely been concerned about own image. My dimensions mean that I wear what fits as opposed to what I like, and as a result the finished product is better behind a keyboard rather than speaking to a crowd.
But as I have gotten older, I have become concerned about a different kind of IMM-AGE (not a typo).
Let me explain: Recently some researchers in Israel and at Stanford University in the US published a rather remarkable research report which if replicated could have important implications for how we approach medical care.
What did they report?
