ScienceDaily — In a finding that has the potential to change the way researchers think about the brain, scientists at Rockefeller University have found dendritic cells where they’ve never been seen before: among this organ’s neurons and connective cells. The immunity-directing dendritic cell had previously been seen in the human nervous system only after brain injury or disease. But the new study shows for the first time that the brain has its own, resident population of dendritic cells that may serve as a line of defense against pathogens that sneak past the blood-brain barrier.
