Research
Cell trafficking unit is one of the national centers of
excellence. The overall goal of our research is to
elucidate the mechanisms that regulate the traffic
of leukocytes in the body. Harmful leukocyte
migration into the heart in myocardial infarction
(reperfusion injury), into the joint tissue in rheumatoid
arthritis and into the pancreas in diabetes are
examples of diseases where leukocytes cause
extensive destruction. These inflammatory diseases
can be prevented by inhibiting leukocyte trafficking
to those sites. Also metastasising malignant cells
often use the same mechanisms as leukocytes
when extravasating from the blood to different
organs or migrating via the lymphatics into the
distant sites. The results obtained in this research can
be utilized when new types of drugs are developed
to treat harmful inflammations and cancer.

Current topics
 Enzymatic and adhesive properties of ectoenzymes (VAP-1 and CD73)
 Targeting lymphocyte and endothelial cell
functions during the development of harmful
inflammations
 Pro- and anti-tumor effects of tumor infiltrating
leukocytes
 Identification of new molecules involved in
lymphocyte traffic within lymphatics
