Tumor immune cell infiltration analyses using TIMER in basal-like breast cancer samples showed that adjusted CCR5 expression was significantly correlated with tumor infiltration of B cell, CD8+ T cell, CD4+ T cell, Neutrophil and Dendritic cell (P < 0.0001), while there was no correlation between CCR5 expression and Macrophage infiltration (P = 0.233) (Figure 1D). This evidence concerns the gene CD8A and neoplasm.
