Protective cellular structure - separates blood from brain. Restricts passage of chemical, toxins, microorganism from blood to the cns. Also protects cns from the peripheral immune system. Prevents things from getting across that would normally get across in blood vessels. Provide support for other cells in the cns (including the ones making up the. More for moving dead cells of the cns, not as good as fighting infection. Wbc (b and t cells) antibodies are normally not present in cns (can"t get across) In an outbreak, the people to first develop the disease are most likely to die.

Not causing disease just yet: invasion into blood, multiplication in blood.
