scRNA-seq study of hippocampal microglia, perivascular macrophages and perivascular fibroblasts in pre-plaque APP-KI mice
Aim of this experiment was to characterize whether SPP1 released from the hippocampal perivascular space could imprint microglia transcriptional states. We performed scRNA-seq analysis on sorted CD140a+ perivascular fibroblast (PVF), CD45highCD11intCD206+ perivascular macrophage (PVM) and CD45intCD11intCX3CR1high microglial cell from dissected hippocampi of 6-month old wild type vs SPP1KO/KO vs AppNL-F mice vs AppNL-FxSpp1KO/KO mice. Cells were isolated from dissected hippocampi as previously described (Sala Frigerio et al.,2019).
