Dendritic Cell Vaccination for Patients With Solid Tumors

Project description:The aim of this study is to evaluate the immunogenicity and clinical efficacy of intradermal vaccination with autologous RNA-modified dendritic cells (DCs) - engineered to express the WT1 protein - in patients with limited spread metastatic solid tumors, i.e. breast cancers, glioblastoma grade IV, sarcomas, malignant mesothelioma and colorectal tumors. Based on the results of our previously performed phase I study with autologous WT1 mRNA-transfected DC, the investigators hypothesize that the vaccination with DC will be well-tolerated and will result in an increase in WT1-specific CD8+ T cell responses.

Expression of genes in the spleen of WT and MUC1.Tg mice immunized with dendritic cells loaded with MUC1 peptide

Project description:Goal of study: To determine differentially expressed genes with potential roles in tolerance and immunity in MUC1-immunized WT and MUC1.Tg mice WT (C57Bl/6) and MUC1.Tg mice were immunized (i.v.) with dendritic cells loaded with sythetic, human MUC1 peptide. At 24h and 72h splenic RNA from vaccination groups (n=3) was pooled and microarray performed.

Dendritic Cell Vaccination in Patients With Advanced Colorectal Cancer

Project description:Dendritic cells loaded with tumor antigens induce cytotoxic T-cells which have been proved capable of killing both melanoma and breast cancer cells. Melanoma and colorectal cancer cells express some common antigens. Hence it is possible to use melanoma lysate to load the dendritic cells with tumor antigens similar to the antigens expressed by the patients’ colorectal cancer cells. The patient receives 10 vaccinations with 14 days between each. The parameters for effect are changes in tumor/metastasis size measured with computed tomography (CT), decrease in serum concentration of carcinoembryonic antigen (CEA), performance status measured by the World Health Organization (WHO) criteria, and Quality of Life.

Transcription profiling of human glioblastoma multiforme tumors taken before dendritic cell vaccination, recurrent tumors after vaccination and control GBM tumors

Project description:Human Glioblastoma Multiforme tumors taken before dendritic cell vaccination, the recurrent tumors taken after vaccination and control GBM tumors from non vaccinated patients. Experiment Overall Design: Six Glioblastoma Multiforme patients underwent surgery. Their brain tumors were removed and analyzed via microarray. The lysate from the tumors were cultured with the patients' dendritic cells and the DCs were injected back into the patients. The patients GBMs returned and they underwent surgery a second time and those tumors were also analyzed via microarray. Tumors from the first and second GBM surgeries of 5 patients who did not receive DC vaccines are included as controls.

Glioblastoma Molecular Characteristics and Immune Microenvironment Associated with Survival Outcomes in Patients Treated with Dendritic Cell Vaccination

Project description:Purpose: Autologous tumor lysate-pulsed dendritic cell (DC) vaccination has shown promising long-term survival in a cohort of patients with newly diagnosed glioblastoma. The purpose of this study was to better understand the mechanisms and modulation of the immune microenvironment underlying the clinical efficacy of DC-based vaccine therapy. Experimental Design: We performed bulk RNA sequencing on tumor samples from patients with newly diagnosed glioblastoma obtained prior to treatment with dendritic cell vaccination. We characterized the molecular mechanisms and immune microenvironments of long-term survivors (LTS, n= 8), medium-term survivors (MTS, n= 13), and short-term survivors (STS, n = 17). Results: There was an enrichment of the mesenchymal subtype of glioblastoma in the long-term survival group. Additionally, decreased tumor cell density, upregulation of cell surface markers, and increased neuronal activity were associated with the longer survival cohorts. Two microglia populations, one associated with increased survival and one associated with decreased survival in the DC-treated cohorts, but not standard of care (SOC) cohorts, are also potentially implicated in response to DC immunotherapy. There were increases in functional activity of the immune environment in longer survivor cohorts. Conclusions: These analyses suggest the potential to identify tumor-based predictive factors that may be associated with favorable responses to DC vaccination in glioblastoma patients; and if validated, these findings may enable better patient selection for future clinical trials.

Antitumor therapeutic vaccination induces immunosuppressive dendritic cells

Project description:Vaccination induces immunostimulatory signals which are often accompanied by regulatory mechanisms such as IL-10, which control T-cell activation and inhibit vaccine-dependent antitumor therapeutic effect. Thus, here we characterized IL-10-producing cells treated with therapeutic vaccines. Although several cell subsets produced IL-10 irrespective of treatment, an early vaccine-dependent induction of IL-10 was detected in dendritic cells (DC). IL-10 production defined a DC population characterized by a poorly mature phenotype, lower expression of T-cell stimulating molecules and upregulation of PD-L1. These IL-10+ DC showed impaired in vitro T-cell stimulatory capacity, which was rescued by incubation with IL-10R and PD-L1-inhibiting antibodies. In vivo IL-10 blockade during vaccination decreased the proportion of IL-10+ DC and improved their maturation, without modifying PD-L1 expression. Similarly, PD-L1 blockade did not affect IL-10 expression, suggesting independent regulation of these molecules. Interestingly, vaccination combined with simultaneous blockade of IL-10 and PD-L1 induced stronger immune responses, resulting in a higher therapeutic efficacy in tumor-bearing mice. These results show that vaccine-induced immunoregulatory DC with dual expression of IL-10 and PD-L1 impair priming of antitumor immunity, suggesting that therapeutic vaccination protocols may benefit from combined targeting of these molecules.
