CD8+ T cells in the MPE can mediate partial cytotoxicity against autologous non-CD45+ tumour containing cells after only 24 h of culture, representing a potential avenue for obtaining tumour-specific T-cell subsets in a minimally invasive manner that may be a useful screening method by which patients that are likely to respond to T-cell-targeted immunotherapy can be identified [35]. The gene discussed is PTPRC; the disease is neoplasm.
