Main Field(s) of Research, Abstract
T cells expressing chimeric T cell receptor constructs are called T bodies. So far, T bodies showed limited survival, proliferation and cytotoxic activity after adoptive transfer in vivo. Dendritic cells (DCs) are essential for the activation and maintenance of both naïve and memory T cells and their function depends on the maturation status. To efficiently prime T cells, mature DCs present both peptide-HLA complexes and appropriate co-stimulatory molecules on their surface. In contrast, immature DCs induce tolerance by presenting antigens to T cells without providing co-stimulatory signals. Cancer is associated with an environment disfavouring DC maturation suggesting silencing of tumor-specific T cells.
The aim of my project is to define DC subsets which give optimal co-stimulatory signals and polarise T bodies into cytotoxic T lymphocytes, effector and central memory CD8 T cells.
