A fight for life Honoring Ralph Steinman′s memory through a preliminary study of in vitro and in vivo anti-tumor effects of BCG-activated dendritic cells

  • Published Date: 2012-08-20
  • Objective To study the direct anti-tumor effects of the Mycobacterium bovis bacillus Calmette-Guerin (BCG) -activated dendritic cell (DC) vaccine in vitro and in vivo. Methods DCs were harvested from bone marrow of C57BL/6 mice and cultured with BCG to stimulate maturation.Activated DCs were evaluated by flow cytometry (FCM) .Activated DCs were co-cultured with the pancreatic tumor cell line, Panc02, and cytotoxic response was measured by the CCK-8 kit.The frequency of activated DCs expressing tumor necrosis factor-related apoptosis-inducing ligand (TRAIL) was measured by FCM, and TRAIL mRNA levels were detected by real-time PCR.C57BL/6 mice were implanted with Panc02 tumor cells by subcutaneous inoculation, and on the seventh day were randomly divided into three groups: untreated control, injected with saline;DC vaccine-treated by intratumoral injection;DC vaccine-treated by subcutaneous injection.For all mice, injections were delivered twice with a one-week interval.On day 15 after the second injection, all the mice were sacrificed to evaluate tumor weights. Results In vitro, the BCG-activated DCs showed obvious typical dendritic structures and the phenotypic increase in CD86 marker expression.Surface expression of TRAIL was also increased on BCG-activated DCs.Activated DCs suppressed the growth of Panc02 tumor cells in culture, and this response was partially alleviated by anti-TRAIL antibody.In vivo, BCG-activated DCs decreased the Panc02-derived tumor weights (vs untreated group) , and intratumoral injection produced lower tumor weights than subcutaneous injection. Conclusion The efficacy of DC-based vaccines for pancreatic cancer may be improved by first activating the DCs with BCG.BCG-activated DCs can directly suppress the growth of Panc02 tumor cells in vitro through TRAIL.Intratumoral injection of the BCG-activated DC vaccine has a more robust anti-tumor effect than the subcutaneous route.
