Abstract

Hepatocellular carcinoma (HCC) is one of the most common and difficult to treat types of cancer worldwide. Antigen‑targeted immunotherapy has the potential to be a novel and effective adjuvant for use in HCC. In the present study, recombinant adeno‑associated virus carrying the α‑fetoprotein gene (rAAV/AFP) and cancer cell lysates were used to pulse antigen‑presenting dendritic cells (DCs) in order to stimulate a cytotoxic T lymphocyte (CTL) response against HCC. rAAV/AFP‑pulsed and cancer cell lysate‑pulsed DCs resulted in a mature DC phenotype with high expression of major histocompatibility complex (MHC) class I, MHC class II, CD80, CD83 and CD86 molecules. However, rAAV/AFP‑pulsed DCs exhibited superiority over cancer cell lysate‑pulsed DCs in terms of stimulating proliferation of T cells, activating T cells to secret interferon‑γ (IFN‑γ) and inducing an AFP‑specific MHC class I‑restricted CTL response. The current data suggest that pulsing of DCs using rAAV/AFP is more effective than the cancer cell lysate‑pulsing technique, and that this technique may be used for the development of immunotherapy in AFP‑positive HCC.
