Title: Are organelles in blood circulation?
Post by: scientizscht on 09/02/2019 19:45:15

I read about organelles circulating in blood.

Where can I read more about it?

White blood cells circulate in blood, and are involved in the immune system.
White blood cells have organelles.
Therefore organelles circulate in the blood.
See: https://en.wikipedia.org/wiki/White_blood_cell

Platelets are involved in clotting, and start out as components of a larger cell.
See: https://en.wikipedia.org/wiki/Platelet

If you have something different in mind (free-floating organelles, or small RNAs), please summarise what you read.

Yes I am talking about free floating organelle parts that are also act as messengers.

Can't find it now though.

Exosomes!

Have a look at https://en.wikipedia.org/wiki/Exosome_(vesicle)

...some of these do carry RNAs that circulate in the bloodstream, and provide a way of signalling between cells, and between different parts of the body.
