Expression of granzyme B in CD107a + NK92 cells co-cultured with Cervical cancer cell (CCC) lines pre-treated or not with the Heme oxygenase 1 (HO-1) inhibitor. CCC were pre-treated with the HO-1 inhibitor (SnPP) for 48 h; afterward, NK-92 cells were co-cultured with CCC for 4 h. Then, the expression of granzyme B was analyzed in CD107a + NK-92 cells co-cultured with HeLA, SiHa, and C-33A pre-treated or not with the SnPP by Flow cytometry (FC). A representative experiment is shown.
