Since their initial discovery in 1973, dendritic cells, the sentinels of the immune system, have turned up in a number of places other than the immune organs. They stand guard in the heart, for instance, and in 2008, the first population native to the brain was identified. New research shows that dendritic cells are not only present in the brain, but active, too. They confront foreign substances and seem to form a barrier between healthy and stricken brain tissue following a stroke.
