In this context, we found that FLT3LG and CCL5 genes, encoding the related proteins contributing to the recruitment of intratumoral DCs by NK cells15,16, are both strongly correlated with CD3E (Fig. 1), THBD and NCR1 (Supplementary Fig. 17a), thus further validating the existence of the DC–NK axis in NB. This evidence concerns the gene THBD and neuroblastoma.
