Key Biological Mechanism In MS possibly identified!

from the article, a very interesting discovery:

Fibrinogen, a blood protein that is involved in coagulation, is not found in the healthy brain. In vivo imaging over different stages of disease revealed, however, that a disruption in the blood-brain barrier allows blood proteins – and specifically fibrinogen – to seep into the brain. Microglia – immune cells that act as the brain’s first line of defense – initiate a rapid response to fibrinogen’s arrival. They release large amounts of chemically reactive molecules called ‘reactive oxygen species.’ This creates a toxic environment within the brain that damages nerve cells and eventually leads to the debilitating symptoms of MS.

    Very interesting! I’m so glad that they seem to be so on the ball with MS research. That cure is just around the corner; I can feel it.
