In addition, PDPN‐expressing CAFs are associated with a high number of CD204+ TAMs, and a low ratio of CD8+ T cells and FOX3+ T cells in immunohistochemical staining of lung adenocarcinoma specimens, suggesting that PDPN‐expressing CAFs help cancer cells escape host immunosurveillance.197. Here, PDPN is linked to lung adenocarcinoma.
