Fig. 4. Association of the cellular composition of immune infiltrates with EMT and immune evasion interactions.
A Correlation between ECI and the infiltration of 22 immune cell subpopulations across 17 types of solid cancer. B Immunohistochemistry assay was performed to mark macrophages or CTLs and detect the expression of Vimentin in lung cancer. C Pearson correlation analysis was used to assess the correlation between Vimentin expression and macrophages or CTLs infiltration. D Distribution of relative infiltration fraction of CD8+ T, T helper cells, M1 and M2 macrophages cells in different cancer subtypes of ovarian cancer and head and neck squamous cell carcinoma. E Unsupervised cluster of pan-cancer tumor samples using uniform manifold approximation and projection based on the relative infiltration fraction of the 22 immune cell subpopulations. F Relative fraction of infiltrating immune cells positively or negatively correlated with ECI across the 17 types of solid cancer. Tumors are ordered by the ratio of infiltrating immune cells negatively correlated with ECI (blue color) vs. infiltrating immune cells positively correlated with ECI (red color). ECI EMT-CYT index, EMT epithelial-mesenchymal transition.
