Abstract

Dendritic cells (DCs) loaded with tumor‑associated antigens (TAAs) are known to be crucial for the antitumor response and are still included in various treatment regimens in cancer immunotherapy research. In the present study, a cell‑based protocol was evaluated, involving the use of original DNA constructs encoding the wide range of TAA epitopes expressed on different epithelial cancers. The constructs were transfected into in vitro‑generated DCs of patients with various types of cancer, including breast, colorectal and non‑small cell lung cancer. The direct cytotoxicity assay of effector cells, activated with the transfected DCs, revealed a significant increase in cytotoxicity against autologous tumor cells. The use of DNA constructs encoding a large number of TAAs for insertion into DCs in vitro, aiming to activate a T‑cell response may prove to be a reliable and unified approach for immunotherapy and for the prevention of relapse in patients with epithelial cancers.
