Effects of novel tribodies or the combinations of Tb535H with the parental mAbs on the secretion of IFNγ by co-cultures of MDA-MB-231 with hPBMCs. The secretion of IFNγ was measured by ELISA on supernatants of MDA-MB-231 cells co-cultured with hPBMCs and treated for 48 h with (A) 53L1 and 53L10 (striped bars), (B) 53D (striped bars), (C) 53G (striped bars). Tb535H (light grey bars), parental immunomodulatory mAbs (dark grey bars) or their combinations (black bars) were also tested at the indicated concentrations for comparison. Co-cultures untreated or treated with the unrelated tribody 53P (C, empty bars) were used as negative controls. Error bars depict means ± SD. P-values for the indicated compounds are: *** P ≤ 0,001; ** P < 0.01; by student’s t-test (two variables)
