B cell migrating through bone channel (IMAGE)
Caption
A newly developed B cell (green in middle of image) migrates from the bone marrow of the skull, where a cluster of other new B cells remain, then through the skull bone, to the protective tissue that covers the brain, which is populated mainly by other cells (blue). Researchers at Washington University School of Medicine in St. Louis have discovered that the immune cells stationed in the protective tissue known as the meninges come primarily from the skull. The finding opens up the possibility of developing therapies to target such cells as a way to prevent or treat brain conditions.
