Defining biomarkers and neoantigen targets for individualized immunotherapies
OUR RESEARCH
Why it matters
The identification of tumor-specific neoantigens is a highly promising strategy to develop and improve personalized cancer immunotherapies leveraging T-cell mediated recognition and elimination of tumor cells. T-cells differentiate between self and non-self-cells by specifically recognizing peptides bound to the major histocompatibility complex (MHC), which define the MHC ligandome. Mass spectrometry-based immunopeptidomics enables the detailed characterization of the MHC ligandome, including unique tumor antigens. This information enables the design of personalized immunotherapies tailored to specifically target the patient's cancer cells, thus potentially enhancing treatment efficacy and reducing adverse effects.
TENZER LAB
Lab focus
We focus on the development, optimization and application of mass spectrometry (MS)-based workflows for quantitative immunoproteomics to facilitate a detailed understanding of the interplay between tumor antigenicity, tumor microenvironment and the anti-tumor immune response. Currently, the research group harbours several high-resolution mass spectrometry instrument platforms, including three timsTOF Pro-2, one timsTOF SCP (Bruker) and two Orbitraps Exploris 480 (Thermo Scientific). With these high-performance instruments, the Tenzer research group investigates the contribution of proteases involved in MHC-I-restricted antigen processing and develops high sensitivity methods and workflows for the in-depth characterization of the immunopeptidome. This will enable high-throughput immuno-phenotyping of quantity-limited clinical samples to define biomarkers and neoantigen targets for individualized immunotherapies.
