Figure 9. The expression of specific prognostic IRGs correlates with the abundance of tumor-infiltrated immune cell types in the CRC tissues. (A) The correlation analysis between CD1B gene expression and the proportions of six types of immune cells (B cells, CD4+ T cells, CD8+ T cells, macrophages, neutrophils, and dendritic cells) in the CRC tissues. (B) The correlation analysis between FCRL2 gene expression and the proportions of six types of immune cells (B cells, CD4+ T cells, CD8+ T cells, macrophages, neutrophils, and dendritic cells) in the CRC tissues. (C) The correlation analysis between MAP2 gene expression and the proportions of six types of immune cells (B cells, CD4+ T cells, CD8+ T cells, macrophages, neutrophils, and dendritic cells) in the CRC tissues.
