The Neoantigens and Cancer Vaccines group (NeoVaCan) is part of the IrsiCaixa Institute for Research on Immunopathologies, a center dedicated to the study of diseasesrelated to the immune system, ranging from viral infections, such as HIV or SARS-CoV-2, to cancer.
Our group focuses on the identification and characterization of neoantigens and tumor-associated antigens, with the aim of developing therapeutic vaccines – personalized or “off-the-shelf” – and other immunotherapies specifically targeting these antigens. In collaboration with the Virology and Cellular Immunology group of IrsiCaixa, we are co-developing preventive and therapeutic vaccines using a proprietary platform based on Virus Like Particles (VLPs).
However, our approach goes beyond the mere discovery of immune targets:
- We also study the host immune response to cancer through immunogenomic analysis of both tumor tissue and peripheral blood, with the aim of understanding the interaction between tumor cells and the immune system. To this end, we use multi-omics techniques combined with immune cell-based functional assays, which allow us to identify the cellular and molecular mechanisms that regulate both anti-tumor immune responses and immune evasion. This knowledge is essential to optimize vaccine design and select the most effective therapeutic combinations.
- Although our neoantigen identification platform is adaptable to multiple cancer types, our main focus is pancreatic ductal adenocarcinoma (PDAC). In this context, the role of the tumor microenvironment (TME) is crucial: rich in stroma, highly immunosuppressive and poorly infiltrated by immune cells. These features can limit the efficacy of therapeutic vaccines. For this reason, we investigate strategies to reprogram the pancreatic TME, focusing on a specific subpopulation of fibroblasts that promotes anti-tumor immunity through activation of the adaptive immune response.
