When distinguishing the molecular subtype, we found that only in BRCA-Luminal, the expression of MYL5 related to the infiltration of immune cells, including B cell, CD8+ T cell, macrophage, neutrophil, and DC, which suggested that the correlation between MYL5 expression and infiltrating immune cells in BRCA was mainly reflected by the luminal classification of BRCA (Figures 5(b)–5(d)). The gene discussed is CD8A; the disease is invasive breast carcinoma.
