CD70 and neoplasm: In addition, we examined the expression of the immunoinhibitor LAG3, the immunostimulators CD70, lipoteichoic acid (LTA), ecto-5′-nucleotidase (NT5E) and ectonucleoside triphosphate diphosphohydrolase 1 (ENTPD1), as well as several regulatory cytokines and chemokines, known for their pro- and anti-inflammatory roles within the tumor microenvironment [7, 14].
