Figure 9. Co-expression of FAP and immune-related genes. (A) Correlation between FAP and MHC genes. (B) Correlation between FAP and chemokines, chemokines receptors, the yellow font represents chemokine receptors. (C) Correlation between FAP and immunosuppressive genes. (D) Correlation between FAP and immune activation genes. *P < 0.05, **P < 0.01, ***P < 0.001.
