CRISPR-Cas9: “New CRISPY Parkinson’s research”

Recently a Parkinson’s-associated research report was published that was the first of many to come.

It involves the use of a genetic screening experiment that incorporates new technology called ‘CRISPR’.

There is an absolute tidal wave of CRISPR-related Parkinson’s disease research coming down the pipe towards us, and it is important that the Parkinson’s community understands how this powerful technology works.

In today’s post we will look at what the CRISPR technology is, how it works, what the new research report actually reported, and discuss how this technology can be used to tackle a condition like Parkinson’s.

My mother: Simon, what is all this new ‘crispy’ research for Parkinson’s I heard about on the news?

Me: Huh? (I was not really paying attention to the question. Terrible to ignore one’s mother I know, but what can I say – I am the black sheep of the family)

My mother: Yes, something about ‘crispy’ and Parkinson’s.

Me: Oh! You mean CRISPR. Yeah, it’s really cool stuff.

My mother: Ok, well, can you explain it all to me please, this ‘Crisper’ stuff?

Me: Absolutely.

CRISPR.101 (or CRISPR for beginners)

In almost every cell of your body, there is a nucleus.

It is the command centre for the cell – issuing orders and receiving information concerning everything going on inside and around the cell. The nucleus is also a storage bank for the genetic blueprint that provides most of the instructions for making a physical copy of you. Those grand plans are kept bundled up in 23 pairs of chromosomes, which are densely coiled strings of a molecule called Deoxyribonucleic acid (or DNA).
