From: Limited response of NK92 cells to Plasmodium falciparum-infected erythrocytes
IFN-γ release of NK92 cells after co-culture with iRBCs. NK92 cells previously cultured with rIL-2 and without rIL-2 (24 hours starvation; NK92s) were co-incubated with 3D7 schizont-iRBCs and uninfected erythrocytes in RPMI-1640 medium (24 hours - 37°C - 5%CO2) and supernatants were subsequently tested for IFN-γ release. iRBCs/uRBCs: supernatants from iRBCs and uRBCs incubated without cells in RPMI-1640; NK92/NK92s: supernatant from cells incubated in normal growth medium and starvation medium, respectively. Values represent mean ± S.E.M.; *p = 0.0001 for comparison with NK92 (p < 0,05 - ANOVA).
