CCL5 and neoplasm: Ad5D24/CCL5/IL‐15 is a genetically modified oncolytic virus encoding CCL5 and IL‐15 genes, and the intratumoral administration of this oncolytic virus could enhance the infiltration of anti‐GD2 CAR‐T cells into the TME, eliminating tumor cells.[169] CCL5 and IL‐15 are involved in the locomotion and migration of NK cells to the tumor site, eliminating tumor cells.[42, 170]
