Figure Lengend Snippet: Figure 6. Longitudinal scRNA-seq analysis of tumor immune compartment reveals anti-tumor CD8+ T cell responses linked to Tyw2 KO (A) In vivo tumor growth following inoculation of WT19, KO13, or KO18 cells into C57BL/6 mice. Time points highlighted with dotted box were used for scRNA-seq analysis. ***p < 0.001, pairwise Bonferroni-corrected Student’s t test. (B) Schematic overview of experimental workflow. Tumors were removed and dissociated at day 18 and day 21 prior to MULTI-seq barcoding, enrichment for CD45+ immune cells, and scRNA-seq. (C) Uniform manifold approximation and projection (UMAP) of immune gene expression space colored by cell type. (D) Bar charts of the percentage of CD8+ T cells among all CD45+ cells in each tumor background at day 18 (D18) and day 21 (D21). Statistically significant changes denoted with propeller test p values (ns, not significant; n = 3 sets of 4–5 pooled tumors). (E) UMAP of CD8+ T cell gene expression space colored by subtype. (F) Dot plot of CD8+ T cell subtype annotation genes. Dot color indicates expression level and size indicates the proportion of cells expressing each gene. (G) UMAP of CD8+ T cell gene expression space colored by sample identities on day 18 (top) and day 21 (bottom). Regions of gene expression space that are enriched in Tyw2 KO or WT samples highlighted with dotted circles. (H) Bar charts of the percentage of exhausted and memory-like CD8+ T cells among all CD8+ T cells in each tumor background at day 18 and day 21. Statistically significant changes denoted with propeller test p values (ns, not significant; n = 3 sets of 5 pooled tumors). (I) Z score heatmap of the average expression of immunosuppression markers in CD8+ T cell subtypes. Z scores for each gene clustered using hierarchical clustering. Exhausted CD8+ T cells highlighted with red box. (J) Representative images of the day 21 Tyw2 KO and WT TME with bar charts of mean ± SEM total (top), exhausted (middle), and proliferative CD8+ T cell percentages (bottom). Exact p values from Welch two-sample t test (n = 5 mice per tumor background). (K) Weighted network graph of IFNG-IFNGR1/IFNGR2 predicted signaling interactions split by tumor background and time point. Nodes colored by cell type, edges weighted by signaling probability and colored by sender cell type. See also Figure S6.
