Figure 8. Correlation between FAP expression and immunosuppressive checkpoint proteins or cytokines in human cancers. (A) Correlation between FAP expression and immunosuppressive checkpoint proteins or cytokines was shown by the heatmap. (B) In BLCA, the association between FAP expression and CSF1R, HAVCR2, IL-10, PDCD1LG2 expression were presented. (C) In THCA, the association between FAP expression and CTLA4, HAVCR2, TIGIT, VTCN1 expression were presented. The Correlation between FAP and immune inhibitors expression were analyzed with Spearman test.
