(DAILY PRESS) — HAMPTON — The immune system is a marvel, working to keep the organs in the body healthy.

Until recently, though, scientists thought the immune system was less proactive with one particular organ — the brain, or central nervous system.

“The understanding was that the two systems don’t interact with each other — or should not interact with other — and they would only interact with each other in pathologies,” said Jonathan Kipnis, head of the Department of Neuroscience at the University of Virginia in Charlottesville.
