Natural (born) killers


Today’s post starts with more of a biology lesson than usual, but it is important to understand where in the grand scheme of things a certain type of blood cell sits.

That type of blood cell has a really cool name: Natural killer cells.

Recently researchers at the University of Georgia (USA) published a report suggesting that natural killer cells may be a key player in the immune system response to Parkinson’s.

Specifically, they found that natural killer cell numbers are higher in disease-affected parts of the Parkinsonian brain, and that natural killer cells digest free floating alpha synuclein aggregates.

In today’s post, we will discuss what natural killer cells are, review this new research report, and explore what this new finding could mean for Parkinson’s.

My daughter recently lost her first tooth, and there was a bit of blood. We patched her up, but also took advantage of the moment to learn a little something about how the body works.

Me: Do you know what that red stuff is?

Me: No.

Extremely relieved little monster: Papa, where does blood come from?

And that was when I got all excited, and pulled out my black board.

Admittedly it took a while, but this was the answer I gave her:
