CD4 and nasopharyngeal carcinoma: The comparison suggested that the infiltration levels of memory B cells, resting memory CD4 T cells, follicular helper T cells, resting NK cells, M2 macrophages, and resting mast cells were significantly higher in NCNT, while the abundances of plasma cells, activated NK cells, M0 macrophages, M1 macrophages, resting dendritic cells, activated mast cells, and neutrophil infiltration in NPC were significantly boosted (Figure 1(c)).
