When a cell is sick or damaged it will send out signals alerting the immune system that something is wrong. If enough of these molecules are released, they will initate an “immune response” and this process is called inflammation.
There is evidence in neurodegenerative conditions (like Parkinson’s and Alzheimer’s) that the inflammation process is involved, and inhibitors of particular aspects of inflammation are being developed as potential therapies for these conditions.
Of particular interest are drugs targeting the NLRP3 inflammasome.
In today’s post, we will discuss what the NLRP3 inflammasome is, look at new research identifying a novel NLRP3 inflammasome inhibitor, and provide an overview/update of where things are in the clinical testing of NLRP3 inflammasome inhibitors for Parkinson’s.
One of the hottest areas of Parkinson’s research world is ‘inflammation’ (cheesy pun intended).
What is inflammation?
When cells in your body are stressed or sick, they begin to release tiny messenger proteins which inform the rest of your body that something is wrong.
When enough of these messenger proteins are released that the immune system becomes activated, it can cause inflammation.
Inflammation is a critical part of the immune system’s response to trouble. It is the body’s way of communicating to the immune system that something is wrong and activating it 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. And there are processes that can amplify the immune response.
One of those processes is called inflammasomes.
What are inflammasomes?
The immune system is our main line of defense against a world full of potentially dangerous disease causing agents. It is a complicated beast that does a fantastic job of keeping us safe and well.
Recently, however, there was an interesting study suggesting that a genetic risk factor for Parkinson’s may be associated with an over-reaction from the immune system in response to infection from a common human food poisoning bug.
Specifically, mice who were missing the gene PINK1 literally had an ‘autoimmune reaction’ to the infection – that is the immune system began attacking healthy cells of the body – while normal mice (with intact PINK1 genes) recovered from the infection and went about their business.
In today’s post, we will explore this new research and discuss why we may need to rethink PINK.

I have had a guts full of all this gut research being published about Parkinson’s.
[NOTE 1.: For the unitiated: A “guts full” – Adjective, Kiwi colloquialism. Meaning ‘Had enough of’, ‘fed up of’, ‘endured to the point of tolerance’]
[NOTE 2.: The author of this blog is a Kiwi]
I really can’t stomach anymore of it.
And my gut feeling suggests that there is only more to come. It would be nice though, to have something else… something different to digest.
So what is today’s post all about?
Gut research of course.
But this gut research has a REALLY interesting twist.
