Immune Modulation in Cancer

The complex cellular and molecular composition of tumors is essential for their pathobiology. We have previously identified molecular mechanisms and candidate molecules responsible for cancer-induced remodeling of the microenvironment and immune system.

Our current work focuses on an in-depth characterization of immune and stromal cells in B-cell lymphomas and brain metastases, with the aim of elucidating novel pro-tumorigenic and immunosuppressive mechanisms, as well as identifying candidate genes and signaling pathways for the development of new therapeutic approaches. This also includes the definition of new prognostic or predictive biomarkers and the identification of mechanisms of therapy resistance. We are particularly interested in cancer-associated T cell exhaustion, the immunosuppressive function of myeloid cells, and the mediators responsible for these two phenotypes. Ongoing projects focus on interleukin-10 (IL-10), interleukin-4-induced-1 (IL4I1) and galectin-9.

We use single cell transcriptome analysis, spectral flow cytometry and proteomic analysis to study primary tumor tissue and blood cells, multiplex immunofluorescence staining and in situ transcript quantification of tissue sections to spatially map the tumor microenvironment, as well as functional assays and treatment studies in vitro and in mouse models to validate the relevance of identified candidate genes and pathways. Our preclinical therapy studies also include the optimization of the treatment of CLL and DLBCL with CAR T-cell products and bispecific antibodies.

To this end, we cooperate with academic and industry partners and are in close contact with our colleagues in the clinic.
