Interaction of tumor cells with infiltrating lymphocytes via CD70 and CD27 in clear cell renal cell carcinoma

CD70 upregulation by hypoxia-inducible factor and CD27(+) lymphocyte tumor infiltration are associated with worse survival in von Hippel-Lindau gene (VHL) mutated clear cell renal cell carcinoma (ccRCC). CD70/CD27 interaction is accompanied by high soluble CD27 levels in the sera of ccRCC patients suggesting that soluble CD27 is a potential predictive tool for anti-CD70 therapy
