Figure Lengend Snippet: Effect of ADT + Fc-enhanced anti-CTLA-4 on DCs (A) Violin plot of myeloid cluster frequencies as percentage of myeloid cells stratified by patient’s 2-year PSA recurrence status. No recurrence, n = 7; recurrence, n = 4. Two-tailed Student’s t test was utilized to test statistical significance. For this and all violin plots to follow, solid lines denote group medians, while dashed lines denote quartiles. (B) Kaplan-Meier curve representing time-to-PSA recurrence in patients stratified by dendritic cell frequency; 95% confidence intervals shown in the shaded areas. There was one recurrence event in DC-high patients and three recurrence events in DC-low patients. Log rank test was performed to evaluate statistical significance. (C) Schematic of pre-clinical validation experiment in the MycCaP model. (D) Percent change in tumor volume relative to baseline volume prior to ADT stratified by treatment group. Average values are represented by solid lines and standard deviations are represented by shaded areas. (E) Kaplan-Meier curve representing survival of mice shown in (D). Log rank (Mantel-Cox) test was used to evaluate statistical significance. (F) Left: supervised UMAP of live CD45 + cells from MycCaP tumors harvested following therapy as denoted in (D and E). Semi-supervised clustering was performed using FlowSOM and clusters were manually annotated according to expression of lineage-defining markers. Right: heatmap of lineage-defining markers across all clusters. Data represent geometric MFI for each marker normalized to the minimum and maximum values across all clusters. (G and H) (G) Frequency of TI-Tregs and (H) frequency of cDCs as percentage of all live CD45 + cells, stratified by treatment group. (I) Left: PaCMAP representing FlowSOM-derived cDC clusters. Clusters were manually annotated according to expression of canonical marker proteins. Right: pseudocolor representation of cDC phenotypes in PaCMAP space stratified by treatment group. (J) Violin plot representing frequency of PD-L2 + DCs as percentage of all DCs stratified by treatment group. (K) Violin plot representing frequency of CD40 + DCs as percentage of all DCs stratified by treatment group. Welch’s t test was used to assess statistical significance. Murine data shown are n = 8 mice per group and representative of two independent experiments each for survival and immune profiling studies.
