IL36A and neoplasm: Interleukin family cytokines play essential roles in inflammation that has been implicated in the initiation and development of lung cancer.[41] In an attempt to screen cytokines and chemokines that were differentially expressed in NSCLC tumor tissues versus normal lung tissues,[42, 43] we identified that IL1F9 (encoding IL‐36γ, an IL‐36 cytokine member) but not IL1F6 or IL1F8 (encoding IL‐36α or IL‐36β, respectively) was highly expressed in the tumor tissues compared to the normal tissues (Cohort 1) (Figure S1A and Table S1, Supporting Information).
