Ssors which will disrupt EGFR inhibition-mediated immune activation. These outcomes may perhaps facilitate strategy for targeting TGF- and COX-2 with EGFR inhibition to overcome tumor immune evasion and reveal a novel aspect of signal targeted therapy in altering immune regulated cytokines.Abbreviations APC: Antigen-presenting cell; CTL: Cytotoxic T cell; EGFR: Epidermal development aspect receptor; E:T: Effector to target; HNSCC: Head and neck squamous cell carcinoma; HPLC: High-performance liquid chromatography; HTL: Helper T cell; mAb: Monoclonal antibody; PBMC: Peripheral blood mononuclear cell; PGE2: Prostaglandin E2; TKI: Tyrosine kinase inhibitor.
