Mission

Chronic Myeloid Leukemia (CML) is a prototypic malignacy that can be controlled by targeted therapy. Patients nowadays have a normal life expectancy and a certain proportion of patients remain in remission after stopping their medication. Still, response kinetics and success rates vary, which can be attributed in part to differences in the immune system. According to our findings, the level of molecular response is associated with a certain level of inflammation, which can be predicted by plasma levels of soluble CD62L, an immune regulatory protein. Within this project, our mission is to undertake validating experiments in bigger patient cohorts to confirm the usefulness of CD62L as a marker of inflammation.

Research

Cancer can only develop when the immune system is not able to eradicate the malignant cells. In recent years, therapies strengthening the immune system have been implemented that lead to complete remission in some patients but have no effects in others. The exact mode of action of these therapies and the mechanisms causing primary and acquired resistance are not completely understood. Currently, we are using high dimensional methods, such as flow cytometry, single cell sequencing and multiplex imaging, to investigate in detail the composition, function and interaction of cells in the tumor tissue in order to determine the pleiotropic effects of immune therapies and to find new treatment approaches.
