Next, to evaluate the activation of non-tumor cells in the tumor tissue in rMV-SLAMblind-injected mice, the gene expressions of mouse Cxcl10, mouse Ccl5, mouse Il12a and mouse Il15 were examined, because these cytokines that are released from antigen-presenting cells, such as macrophages and DCs, recruit NK cells in tumors (CCL5 and CXCL10) or regulate NK cell activation (IL12a and IL15)36. This evidence concerns the gene IL15 and neoplasm.
