Moreover, S. cerevisiae in the CB group correlated positively with the naïve Tc % of Cytotoxic Lymphocytes T, while in the NB group, we observed a positive correlation with the CD4-/CD8- % of Lymphocytes T and a negative with the Mo CD273 + % of Monocytes (Fig. 3, Table S5). This evidence concerns the gene CD4 and neuroblastoma.
