CD8 T cells were quantified using CD8A gene expression and a Trm gene signature (Figure 5C, D) (CD8A, ITGAE (CD103), ZNF683 (HOBIT)); CMS1 contained the highest T cell abundance amongst the CMS subgroups, while the basal-like subgroup within BC had the highest T cell abundance. The gene discussed is ZNF683; the disease is breast cancer.
