Regarding CAR-T cells delivery in GBM, Xie et al. 2021 generated ultra-small superparamagnetic particles of iron oxide (USPIOs) glucose-coated nanoparticles to facilitate tracking the EGFRvIII- and IL13Rα2- CAR-T cells in human GBM xenografts. This evidence concerns the gene IL13RA2 and glioblastoma.
