Something LRRKing in the immune system

 

 

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.

What did they find?
