| Outline of Final Research Achievements |
Tumor microenvironment can determine the biological behavior of the cancer. The aim of the study was to investigate roles of EBI3 in the formation of anti-tumor immune microenvironment. We examined roles of EBI3 using our newly designed transgenic mice expressing dominant-negative inactive form EBI3 and analyzing tumor formation in those mice treated with chemical carcinogens. Carcinogen-induced tumors developed earlier and more frequently in the transgenic mice rather than wild type mice, suggesting that EBI3 involves in the antitumor immune microenvironment. Clinicopathological examinations also suggested that higher infiltration of EBI3 expressing cells into tumor tissues is a favorable prognosticator in various types of solid cancer other than pancreatic cancer.
