To determine which cytokines might prolong the lifespan of neutrophils, we first screened the genetic expression of proinflammatory cytokines in human head and neck cancer by TCGA analysis (Figure S3D, Supporting Information) and stimulated neutrophils in tumor tissue using differentially or highly expressed cytokines including IL1α, ILβ, IL8, IL33, CXCL5, G‐CSF, M‐CSF, GM‐CSF, TGFβ1, IFNα, CXCL1, and TNFα. The gene discussed is TNF; the disease is head and neck cancer.
