ITGAE and breast cancer: Using the GSEA methodology (Subramanian et al., 2005), we found that the signatures obtained for breast cancer or lung tissue CD103+ TRM cells (Hombrink et al., 2016; Kumar et al., 2017; Savas et al., 2018) were enriched in CD103+ T cells compared with CD103− T cells induced by DC3s (Figure 7D).
