Intercellular adhesion molecule 2 increases the antitumor immunity by accelerating the infiltration of immature myeloid dendritic cells in the tumor epithelium, followed by cellular immune responses, and promoting the susceptibility of the tumor cells to cytotoxic T-cell-mediated cytolysis in intraductal papillary mucinous adenoma (49). Here, ICAM2 is linked to neoplasm.
