In the current study, we investigated whether anti-CD27 monoclonal antibody can enhance the antitumor efficacy of a dendritic cell-based vaccine in prostate cancer-bearing mice. The overall therapeutic effect of a dendritic cell-based vaccine for prostate cancer remains moderate. A prostate cancer model was established by subcutaneous injection of RM-1 tumor cells into male C57BL/6 mice on day ...
The primary goal of this Phase I study was to assess the safety and bioactivity of tumor lysate-pulsed dendritic cell (DC) vaccination to treat patients with glioblastoma multiforme and anaplastic astrocytoma. Adverse events, survival, and cytotoxicity against autologous tumor and tumor-associated antigens were measured. Fourteen patients were thrice vaccinated 2 weeks apart with autologous DCs...
Neuroblastoma is a pediatric cancer of neural crest origin that accounts for 12% of all pediatric cancer deaths. Despite improved survival in patients that receive standard care plus anti-GD2 immune therapy, there remains a 40% mortality rate in high-risk patients. This high mortality emphasizes the need for continued testing of immune-based therapies for the treatment of refractory neuroblasto...
PURPOSE Whole tumor lysates are promising antigen sources for dendritic cell (DC) therapy as they contain many relevant immunogenic epitopes to help prevent tumor escape. Two common methods of tumor lysate preparations are freeze-thaw processing and UVB irradiation to induce necrosis and apoptosis, respectively. Hypochlorous acid (HOCl) oxidation is a new method for inducing primary necrosis an...
Tumor antigens are the primary target of therapeutic cancer vaccines. We set out to define and compare the expression pattern of tumor antigen genes in esophagus carcinoma biopsies and in an allogeneic tumor lysate-based cancer vaccine, MelCancerVac®. Cells used for vaccine production were treated with the DNA methyltransferase inhibitor 5-aza-2'-deoxycytidine (5-aza-CdR) to determine whether t...

PROBLEM Dendritic cell (DC)-based cancer therapies are favored approaches to stimulate anti-tumor T-cell responses. Unfortunately, tolerance to tumor antigens is difficult to overcome. Biodegradable poly(lactic-co-glycolic acid) (PLGA) nanoparticles (NP) are effective reagents in the delivery of drugs and tumor-associated antigens (TAA). In this study, we assessed the capacity of a PLGA NP-base...
Electroporation of dendritic cells (DCs) with tumor lysate elicited greater antitumor responses in vitro and in vivo, using less lysate than standard coincubation. Electroloaded DCs had normal surface marker expression and matured into competent antigen-presenting cells. In a renal carcinoma (RENCA) model, mice were pretreated with lysate-loaded DCs before tumor challenge. Mice that received DC...
Background and Objective: Using dendritic cells (DCs) loaded with tumor antigens as a therapeutic strategy against tumors has been proposed. In order to increase the efficacy of DCs, a variety of factors such as TLR ligand molecules and bacterial products are used. In this study, the protein components of the bacteria Listeria monocytogeneses (LM) for induction of dendritic cell maturation were...
BACKGROUND Cytotoxic T-lymphocyte-mediated tumor immunity against major histocompatibility antigen class II-negative tumors requires help from CD4(+) T-cells. The major antigen presenting cells for CD4(+) cell activation are dendritic cells. Studies in mice and humans have demonstrated the potent capacity of these cells to induce specific antitumor immunity. OBJECTIVE To control the growth of...
