(c) High expression of IFN-γ (IHC, ×200). (d) Low expression of IL-12A (IHC, ×100). (e) High expression of IFN-γ (IHC, ×200). (f) Low expression of IL-17A (IHC, ×100). (g) High expression of IL-17A (IHC, ×200). (h) The expression of inflammatory cytokines in normal breast ductal epithelium and stromal cells (IHC, ×200).
