Engineered cell-based therapies for lung cancer have so far been designed to target epidermal growth factor receptor (EGFR) and variant III (EGFRviii), glypican 3 (GPC3), human epidermal growth factor receptor 2 (HER2), Protein tyrosine kinase 7 (PTK7), erythropoietin-producing hepatocellular carcinoma A2 (EphA2), mesothelin (MSLN), prostate stem cell antigen (PSCA), mucin 1 (MUC1), carcinoembryonic antigen (CEA), natural killer group 2D (NKG2D), tyrosine kinase-like orphan receptor 1 (ROR1), and programmed cell death ligand 1 (PD-L1),lung-specific X (LunX), and delta-like 3 (DLL3) (101–104). The gene discussed is MUC1; the disease is lung carcinoma.
