B cells of the immune system discovered in the meninges

Different types of white blood cells found in the outer layer of the meninges of mice. Examining around 3,000 cells, scientists analysed which genes are active in every single cell and identified 19 different cell types. One dot corresponds to an individual cell. The closer the dots are to each other, the more similarities there are between the cells. About 1700 active genes were detected per cell. Schafflick D, Wolbert J, Heming M et al./Nat Neurosci 2021 - A comprehensive analysis of white blood cells in the tissue surrounding the brain / Study published in the journal "Nature Neuroscience" The brain holds numerous unsolved medical mysteries. Only a few years ago it was discovered that the outer layer of the meninges is interlaced with lymphatic vessels.
