LB BRCA patients with low expression of LINC00426 have reduced infiltration of naive B cells (p = 0.0242), plasma cells (p = 0.0324), CD8 T cells (p < 0.0001), memory CD4 T cells (resting) (p = 0.0220), memory CD4 T cells (activated) (p < 0.0001), gamma-delta T cells (p < 0.0001), M1 macrophages (p < 0.0001) and increased infiltration of memory B cells (p < 0.0001), NK cells (resting) (p < 0.0001), M0 macrophages (p < 0.0001), M2 macrophages (p < 0.0001), mast cells (resting) (p = 0.0018), mast cells (activated) (p = 0.0005) and eosinophils (p < 0.0001). Here, CD8A is linked to invasive breast carcinoma.
