Microglia is a type of glial cell which acts as the main form of immune defense in the central nervous system (brain and spine).
They make up between 10-15% of all brain cells, and are extremely sensitive; they are supported by potassium.
These cells move about and "eat" plaque, damaged neurons, and infectious agents.
The blood-brain barrier prevents most infectious material from entering the brain, but if it does, microglia must act very quicky to decrease inflammation and destroy the infection.
Because the blood-brain barrier (BBB), prevents antibodies from crossing it, microglia do the job of fighting infection instead.
If inflammation increases instead of decreases, the microglia stop functioning effectively.
