Moreover, the results of xCell algorithm showed that the immune score and microenvironment score in cluster 1 are higher than cluster 2 (Figures 4A, B), for tumor-related immune cells, the Th2 cell and Myeloid dendritic cell were found to be remarkably enriched in cluster 1 (Figures 4C, D), while the NK T cell and CD4+ effector memory T cell were remarkably enriched in cluster 2 (Figure 4E, F). Here, CD4 is linked to neoplasm.
