Abcc3 is responsible for NK cell chemo-resistance. (A and B) Relative expression of Abca6 and Abcc3 transporters in blood NK cells at 72 h, **p < 0.001. (C and D) Time course of Abca6 and Abcc3 expression in PBLs from naïve mice (n = 20) treated in vitro with 1 μM TMZ or DMSO; *p = 0.01, **p < 0.005 and ***p < 0.0001. (E and F) Abcc3 levels in NK and CD8+ T cells from glioma-bearing mice (n = 5/group) after three treatments of TMZ (red line) or DMSO (green line). (G and H) multidrug-resistance activity assay in NK and CD8+ T cells from PBLs of naive mice (n = 25) treated in vitro with 1 μM TMZ or DMSO for 4 h. MAF values > 25 are indicative of multidrug-resistant phenotype.
