Project description:CD138-high plasma cell subsets were analyzed by single cell RNA-sequencing to identify gene expression differences between long- and short-lived plasma cells. Five different CD138-high subsets were analyzed based upon differential B220 expression and uptake of the fluorescent glucose analog 2NBDG: splenic B220+2NBDG-, B220+2NBDG+, B220-2NBDG-, B220-2NBDG+, and bone marrow B220-2NBDG+ cells.

Project description:Microglia are highly responsive to their local environment and signals from the periphery. Blood plasma proteins readily permeate the healthy brain parenchyma. However, whether microglia are responsive to such proteins is unclear. Here, we identify a stable population of microglia takes up plasma proteins in a region-specific manner in healthy brains. To understand these microglia at the single cell transcriptomic level and correlate their transcriptome with plasma uptake intensity, we sorted plasma-high, plasma-low, and plasma-negative microglia from young mice (3-month-old) and perform plate-based scRNA-seq.
