Figure Lengend Snippet: FIGURE 5 IL-18/poly I:C-primed NK cells kill hepatic stellate cells in a TRAIL- involved degranulation manner. IL-18 and poly I:C-primed NK cells were treated by anti-TRAIL or isotype antibody before coculture. HSC death was measured (A), and NK cell degranulation was evaluated by CD107a expression (C). Soluble TRAIL was added to cell coculture, the cell death of HSCs (B) and CD107a expression of NK cells (D) was shown. Results were shown as mean ± SEM of 6 independent experiments performed with 6 different donor NK cells. *P < 0.05, **P < 0.01, ***P < 0.001, paired t-test. The kinetics of the activated NK cell-mediated LX2 cell apoptosis were observed by using live-cell imaging (E).
