CD4 and neoplasm: We found that high BRCAness tumor was associated significantly with high infiltration of several anti-cancerous immune cells, such as M1 macrophages, T helper (Th) type 1 cells, CD4+ memory T cells, and dendritic cells (Fig. 4A; all p < 0.001), as well as B cells and Th2 cells (p = 0.002 and < 0.001, respectively), in TCGA (Fig. 4A).
