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.
