Single-cell profiling of CNS border compartment leukocytes reveals that B cells and their progenitors reside in non-diseased meninges. featured image

Single-cell profiling of CNS border compartment leukocytes reveals that B cells and their progenitors reside in non-diseased meninges.

Based on single-cell transcriptomics, we here identify a highly location-specific composition and expression profile of tissue-resident leukocytes in CNS border compartments …
