Project 2. Identification and characterisation of novel classes of therapeutically relevant tumour neo-antigens

Project Details

Knowledge about the peptide repertoire presented by human leukocyte antigens (HLA) holds the key to unlock target-specific cancer immunotherapies as vaccines and adoptive cell therapies. The recent advances in mass spectrometry approaches have greatly improved our ability to comprehensively characterise the HLA immunopeptidome of tumour cells. However, only a fraction of tumour peptides identified by immunopeptidomics strategies are real immunogenic epitopes able to elicit therapeutically relevant immune responses.

Through the combination of immunopeptidomics and an advanced immunogenicity screening pipeline, this project aims at identifying and characterising novel classes of tumour neo-antigens suitable for therapeutic purposes.

The immunogenicity of the tumour neo-antigens identified will be also validated by detecting specific T-cell responses in the blood of cancer patients, thus paving the way for the development of new immunoassays for improved monitoring of tumour antigen-specific immune responses in patients treated with immunotherapies.

The project will also exploit our nanoparticle-based vaccination platform targeting cross-presenting dendritic cells in vivo to investigate the feasibility and efficacy of vaccination approaches targeting the new antigens identified in suitable humanised mouse models.
