Yoon et al. [66] showed RNA encoding HER2 CAR electroporated CIK cells produce cytokines including IFN-γ, tumor necrosis factor-alpha (TNF-α), and granulocyte-macrophage colony-stimulating factor (GM-CSF), and show specific cytotoxicity against tumor cell lines expressing HER2. Here, ERBB2 is linked to neoplasm.
