Figure 5. Immunological analysis of ACE2 and IL6. (A) The pathological sections of tumor tissue and normal tissue which was stained by ACE2 and IL6 antibody. Each group has 2 duplicate samples. (B) The heatmap showed the correlation of 6 immunological factors (lymphocyte, immune-inhibitor, immune-stimulator, MHC molecule, chemokine, and chemokine receptor) vs. mRNA expression, copy number and methylation of ACE2 and IL6.
