In the current series of (eight) short posts we will explore how Progressive MS develops and indicate how it may be treated, compared with Relapsing MS. So whilst Ryan seeks to do this with vegetables, we will stay with the transport theme.
This starts with roads (blood vessels) along which cars (white blood cells) travel, with the aim of destroying something.
These cars travel along roads and once they get in the brain represented by a car park they cause havoc. These cars (white blood cells) leave the road (blood) and can enter the capark (brain) via an open barrier (blood brain barrier). Once inside they can damage the myelin-forming cells.
Not Interested in this simplified approach. See Prelude.
