Expansion of dendritic cells by Flt3L administration also induced parallel amplification of Newcastle Disease Virus- and tumor-specific T cells, including CD8 + T cells reactive to newly described neoepitopes, promoting long-term tumor control and indicating that mobilizing dendritic cells to increase tumor antigen cross-presentation can improve the efficacy of oncolytic virotherapy. This evidence concerns the gene FLT3LG and neoplasm.
