The inflammasome field is heating up

 

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?

Sensing seriousness about senolytics

 

Researchers are building as ever increasing amount of evidence supporting the idea that as our bodies age, there is an accumulation of cells that cease to function normally. But rather than simply dying, these ‘non-functional’ cells shut down and enter a state which is refered to as ‘senescence‘.

And scientists have also discovered that these senescent cells are not completely dormant. They are still active, but their activity can be of a rather negative flavour. And new research from the Rockefeller University suggests that these senescent cells could potentially explain certain aspects of Parkinson’s.

The good news is that a novel class of therapies are being developed to deal with senescent cells. These new drugs are called senolytics.

In today’s post, we will discuss what is meant by senescence, we will review the new data associated with Parkinson’s, and we will consider some of the interesting senolytic approaches that could be useful for PD.

Humans being are great collectors.

We may not all be hoarders – as in the image above – but everyone has extra baggage. Everybody has stuff they don’t need. And the ridiculous part of this equation is that some of that stuff is kept on despite the fact that it doesn’t even work properly any more.

The obvious question is:

Why do we hold on to stuff long after we don’t use it anymore?

Oh, and don’t get me wrong – I’m not talking about all that junk you have lying around in your house/shed.

No, I’m referring to all the senescent cells in your body.

Huh? What are senescent cells?
