An analysis of the CD8+ Vα2/Vβ5+ T cell infiltration in the tumour revealed that the PBS group had the lowest percentage of infiltration (0.07 ± 0.03%), while the highest percentage of transferred cells was found in the groups inoculated with OT-I CD8+ T cells or APS-MNP-loaded OT-I CD8+ T cells but had not been exposed to an EMF (0.14 ± 0.03% and 0.14 ± 0.07%, respectively). This evidence concerns the gene CD8A and neoplasm.
