Fig. 7From: A meta-validated immune infiltration-related gene model predicts prognosis and immunotherapy sensitivity in HNSCCImmunohistochemistry analysis of the protein expression of ISG20 and CTSL1 in HNSCC and normal tissues. A-E The expression of ISG20 was detected by immunohistochemistry in 5 patients with HNSCC (Magnification × 200). F The expression of ISG20 was detected by immunohistochemistry in normal head and neck squamous cell tissue (Magnification × 200). G-K The expression of CTSL1 was detected by immunohistochemistry in 5 patients with HNSCC (Magnification × 200). L The expression of CTSL1 was detected by immunohistochemistry in normal head and neck squamous cell tissue (Magnification × 200).
