Project description:Poly I:C is a powerful immune adjuvant as a result of its agonist activities on TLR-3, MDA5 and RIG-I. Intratumoral administration is conceivably safer than systemic delivery and allows concentrate proinflammatory adjuvanticity in the tumor microenvironment and tumor-draining lymphoid tissue. BO-112 is a nanoplexed formulation of Poly I:C complexed with polyethylenimine that causes tumor cell apoptosis showing immunogenic cell death features and that upon intratumoral release results in more prominent tumor infiltration by T lymphocytes. Intratumoral treatment of subcutaneous tumors derived from MC38, 4T1 and B16F10 with BO-112 leads to remarkable local disease control mediated by CD8+ T lymphocytes, as concluded from selective depletion experiments. Some degree of control of non-injected tumor lesions upon BO-112 intratumoral treatment was found in mice bearing bilateral B16OVA melanomas, that was enhanced when co-treated with systemic anti-CD137 and anti-PD-L1 immunomodulatory mAbs. More abundant CD8+ T lymphocytes were found in tumor-draining lymph nodes and in the tumor microenvironment following intratumoral treatment with BO-112. Enhanced numbers of tumor-specific CTLs recognizing melanosomal antigens and ovalbumin were readily detected among them. Genome-wide transcriptome analyses of injected tumor lesions were consistent with a marked upregulation of the type-I interferon pathway. Intratumorally delivered BO-112 is being tested in cancer patients (NCT02828098) and our results in mice suggest prominent anti-tumor local control through its proimmune effects. To compare the in-vitro and in vivo transcriptional profile induced by BO-112, B16-OVA cell lines were incubated with BO-112 for 24h. BO-112 induces a specific transcriptional profile in B16-OVA cell cultures. Key immunoregulatory genes were found to be differentially expressed between BO-112 and Vehicle-incubated B16-OVA cells.

Project description:This laboratory focuses on selectin mediated recruitment during adoptive immunotherapy for metastatic cancer. This study seeks to determine changes in the expression levels of Fucosyltransferases, Selectins, and cytokines in normal and inflamed mouse skin, melanoma tumor tissue of different sizes, and tumor cells grown in culture. Since the ability to treat the tumor effectively is directly related to the size of the tumor, differences in glyco-expression patterns may be of interest. In this study, five groups were hybridized and analyzed using the GLYCOv2 array. Each group was analyzed in triplicate. The groups were: Normal mouse skin, normal mouse skin inflamed by treatment with Oxazolone, B16-OVA melanoma tissue from 6 day tumors, B16-OVA melanoma tissue from 11 day tumors, and B16-OVA grown in cell culture.

Intratumorally delivered BO-112 is being tested in cancer patients (NCT02828098) and our results in mice suggest prominent anti-tumor local control through its proimmune effects. Intratumoral administration of BO-112, a nanoplexed form of PolyI:C, triggers an efficacious antitumor response in different tumor models as a consequence of proimmflamatory activity and its direct effects in tumor cells. BO-112 local administration induces direct tumor cell death by apoptosis, showing signs of immunogenic cell death, and a strong release of IFNα/β and other proinflammatory mediators. As a result, a tumor-specific CD8+ immune response is mounted or augmented to the point of controlling tumor progression both in the locally injected lesion and to some extent on distantly implanted tumor nodules

Project description:Whole Genome Sequencing of the murine breast cancer cell line 4T1 and of the murine melanoma cell line B16-ova was carried out with the aim of identifying somatic mutations. We also ran deep Mass Spectrometry proteomics analysis on the same cell lines, aiming to determine which somatic mutations carry over to the protein expression level. Further, we tested these cancer specific protein epitopes (putative neoantigens) for immunogenicity using mouse models. Finally, the putative neoantigens that showed good immunogenic potential were used in tumor growth control experiments with mice engrafted with the two tumor cell lines. In these experiments we tested whether cancer vaccines based on individual neoantigen peptides (MHC-I) restricted the growth of the tumor compared to adequate controls. The overall aim of the project is to validate the ability of our multi-omics/bioinformatics pipeline to identify and deliver neoantigens that can be used to suppress tumor growth.
