CD3E and neuroblastoma: Using previously validated specific immune gene signatures28 as an estimate of the immune cell abundance, we found that NB samples with high levels of CD3E (median split) of both Nanostring-NB and SEQC-NB cohorts were significantly enriched of different lymphoid and myeloid cell populations (Fig. 2 and Supplementary Fig. 3, Supplementary Data 3).
