Based on the immune infiltration of 22 immune cells in the 113 normal cases, 122 TNBC cases, we could see that the tumor group of the TNBC data had significantly lower proportions of T cells regulatory (Tregs), T cells CD8, T cells CD4 naïve, T cells gamma delta, T cells CD4 memory resting, and eosinophils (P-value < 0.01), while the proportions of B cells memory, neutrophils, B cells naïve, monocytes, macrophages M1, and plasma cells were notably increased (P- value < 0.001) (Figure 7). Here, CD4 is linked to neoplasm.
