Also, tumor cells incubated with Ara-C stimulated CD4+ or CD8+ T cells, releasing the highest IL3 (CD4+ T: 1729.28 ± 92.46 pg/ml, CD8+ T: 999.39 ± 133.09 pg/ml), TNFα (CD4+ T: 613.45 ± 28.26 pg/ml, CD8+ T: 1155.64 ± 72.15 pg/ml), and IFNγ (CD4+ T: 107.60 ± 12.69 ng/ml, CD8+ T: 84.21 ± 1.23 ng/ml) in the presence of diabody. Here, TNF is linked to neoplasm.
