Lymphocyte recirculation through the body is not a random process, but lymphocytes migrate through selected tissues depending on their activation and maturation stage, subtype, and tissue of origin. This tissue-specific migration is dependent on selected adhesion molecules on lymphocytes as well as endothelial cells, and production of tissue-specific chemokines and expression of their respective receptors on circulating lymphocytes.

The aim of our project is to characterize the mechanisms of lymphocyte recruitment to mucosal tissues, both during steady state and in gastrointestinal tumors. We use tissue resection material from cancer patients and blood from volunteers, and also use a mouse model of colon cancer. We have also established an in vitro system to examine transendothelial migration of lymphocytes. More specifically, we are studying the expression of endothelial adhesion molecules and chemokines in unaffected and tumor tissues, and how these shape the repertoire of tumor-infiltrating lymphocytes. We also examine the ability of tumor cells to directly influence the function of endothelial cells and their expression of homing-related molecules. Finally, the ability of regulatory T cells to influence lymphocyte recruitment in cancer patients is determined. In a second line of studies, we are investigating the effector functions of different types of T cells in gastrointestinal tumors, and how these are influenced by the tumor microenvironment and the presence of regulatory T cells. The knowledge gained from these studies will be used to improve current strategies for mucosal immunization and immunotherapy against gastrointestinal tumors.
