These results prompted us to evaluate whether APS-coated MNPs attached to CD8+ T cell membranes could also magnetically target and accumulate tumour-specific CD8+ T cells in a solid tumour and in its draining LNs with the use of a magnet; though less sophisticated than antibody-modified MNPs and magnetic recruitment with MRI guidance, this approach is easier to undertake. The gene discussed is CD8A; the disease is neoplasm.
