Project Summary

In contrast to the very successful use of CD19-specific CAR T cells for the treatment of various leukemias and lymphomas, the therapeutic efficacy of CAR T cells against solid tumors has been very limited to date. One of the main reasons for this is the immunosuppressive tumor microenvironment. Preclinical studies have shown that equipping CAR T cells with accessory molecules such as co-receptors and chemokine receptors can significantly improve efficacy in such entities.

We were able to identify novel strategies that lead to a significant increase in CAR T cell function, including the modulation of transcription factors and the use of a cytokine superagonist. The aim of this project is to combine these novel strategies with chemokine receptors and to define the optimal T cell subsets for modification and thus significantly improve the therapeutic options.
