Transcriptional response of meningeal lymphocytes post-SAH. A, B UMAP projection of meningeal T cell subclusters colored by clusters (A) and samples (B). C Violin plot showing the expression levels of marker genes in each T cell subpopulation. D, E UMAP embedding of meningeal B cell subclusters colored by clusters (D) and samples (E). F Dot plot showing the expression levels of marker genes in each B cell subpopulation. G Developmental trajectories of meningeal B cell subclusters. H GO enrichment analyses of DEGs among the B cell subpopulations. I Bubble plot showing the intercellular communication of MHC II signaling pathway at 72 h post-SAH
