In this context, our immunohistochemistry staining results suggested predominant expression of IL‐36γ in the epithelium (Figure S1D, Supporting Information), which is consistent with recent single‐cell mRNA‐seq data that the levels of IL1F9 in epithelial cells are higher than those in other types of cells in the tumors from CRC patients and that IL1F9 is undetectable in CD45+ immune cells from the inflamed mucosa of patients with ulcerative colitis.[32, 33]. The gene discussed is IL36G; the disease is colorectal carcinoma.
