CCL20 and neoplasm: In addition, OV-based therapy is influenced by the replicative capacity, individual OV biology, and the interaction of the OVs with the tumor and stromal cells.40 Thus, in this study, we further hypothesized that intratumor expression of the MIP-3α gene using a recombinant oncolytic NDV would result in the attraction of peripheral DCs into the virus-infected tumors and subsequently lead to the priming of a stronger and more specific cellular and humoral immune response against tumors that will inhibit tumor growth and promote the survival of the host.
