We found that CAF markers, such as fibroblast activation protein (FAP), ACTA2 (α-SMA), and beta-type platelet-derived growth factor receptor (PDGFRB) were associated with the infiltration of macrophages in cervical cancer in the Tumor Immune Estimation Resource (TIMER) database (Figure 3C). The gene discussed is PDGFRB; the disease is cervical carcinoma.
