CCL5 and neoplasm: 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.
