Extended Data Fig. 4. B/plasma cell-specific analysis.

Extended Data Fig. 4

a, B/plasma cell UMAP colored by fine-grained cell state clusters, b Expression of selected surface proteins among B/plasma cells. Cells are colored from blue (low) to yellow (high), c, Heatmap of surface protein expression in B/plasma cell clusters colored according to the average normalized expression across cells in the cluster, d, Heatmap of gene expression in B/plasma cell clusters colored according to the average normalized expression across cells in the cluster, scaled for each gene across clusters, e, Distribution of B/plasma cells across clusters, stratified by CTAP. The size of each segment of each bar corresponds to the average proportion of cells in that cluster across donors from that CTAP. f, Number of B/plasma cells per individual, stratified by CTAP. Points represent individuals (N = 82); OA (N = 9), EFM (N = 7), F (N = 11), TF (N = 8), TB (N = 14), TM (N = 12), M (N = 18). Box plots show median (vertical bar), 25th and 75th percentiles (lower and upper bounds of the box, respectively) and 1.5 x IQR (or minimum/maximum values; end of whiskers). g, Heatmap of correlations between select T and B cell subsets, colored by Pearson correlation between per-donor proportions. h, Schematic representation of the experimental design of the T cell functional assays and representative flow cytometry plots showing gating of plasmablasts (CD27hi CD38hi CD19+ cells), ABC B cells (CD11c+ CD21 CD19+ cells) and dead target cells (Annexin V+). Parts of this schematic were created using BioRender.
