Figure Lengend Snippet: Phenotypic modulation of T cells and enhanced priming by anti-CTLA4-NF (A) PaCMAP plot of NeoRED-P patient tumor-infiltrating CD8 T cells by CyTOF. Clusters were derived from FlowSOM. (B) Pseudocolor density plots of CD8 T cells in PaCMAP space stratified by treatment group. (C) Expression of CD39 and 4-1BB by geometric MI on CD8 T cells as represented by color mapping on PaCMAP plot. (D) Violin plot representing frequency of manually gated CD39 + 4-1BB + CD8 T cells as a percentage of all CD8 T cells stratified by treatment group. Untreated, n = 7; ADT, n = 8; ADT + anti-CTLA4-NF, n = 8. Single patient with MSI hi status called out in plot. For this and all violin plots to follow, solid lines denote group medians, while dashed lines denote quartiles. (E) PaCMAP plot of NeoRED-P patient tumor-infiltrating CD4 + FoxP3 - Tconv cells by CyTOF. Clusters were derived from FlowSOM. (F) Pseudocolor density plots of CD4 Tconv cells in PaCMAP space stratified by treatment group. (G) Expression of CD39 and 4-1BB by geometric MI on CD4 Tconv as represented by color mapping on PaCMAP plot. (H) Violin plot representing frequency of manually gated CD39 + 4-1BB + CD4 Tconv cells as a percentage of all CD8 T cells stratified by treatment group. Untreated, n = 7; ADT, n = 8; ADT + anti-CTLA4-NF, n = 8. Single patient with MSI hi status called out in plot. (I) PaCMAP plot of MycCaP-infiltrating CD8 T cells by 45-parameter flow cytometry in response to ADT, ADT + anti-CTLA4 (ND), or ADT + anti-CTLA4 (D). Clusters were derived from FlowSOM. (J) Pseudocolor density plots of CD8 T cells in PaCMAP space stratified by treatment group. (K) Expression of CD39 and 4-1BB by geometric MFI on CD8 T cells as represented by color mapping on PaCMAP plot. (L) Violin plot representing frequency of manually gated CD39 + 4-1BB + CD8 T cells as a percentage of all CD8 T cells stratified by treatment group. (M) Biaxial plots representing expression of CD44 and Ki67 on CD8 T cells in tumor-draining lymph nodes of mice shown in (I–L). (N) Biaxial plots representing expression of CD44 and Ki67 on CD4 + FoxP3 − Tconv cells in tumor-draining lymph nodes of mice shown in (L–O). (O) Violin plots representing frequencies of CD44 + Ki67 + CD8 and CD4 Tconv cells as a percentage of parent populations stratified by treatment group. Two-tailed Welch’s t test was used to assess statistical significance. All murine data shown are n = 7 per group and representative of two independent experiments each for survival and immune profiling studies.
