Figure 1. SLAMF3 blockade in human hepatocytes is associated with lower susceptibility to HCV.

Figure 1

(A) SLAMF3 was stained in primary human hepatocytes (PHHs) and cells from the Huh-7 human hepatoma cell line with a specific antibody (HLy9.1.25 clone; grey) and an isotype-matched control (empty). One of four independent experiments is shown. Huh-7 cells were transfected with scrambled control (sc) siRNA or three specific siRNAs (#1, #2 and #3) targeting SLAMF3, prior to infection with HCVcc; siRNA efficiency was checked by quantifying SLAMF3 mRNA (B) and the CD81 expression level (C) by flow cytometry analysis at 48 h post-transfection. Results are presented as the mean ±SD (n = 3). Intracellular viral RNA was quantified at 72 h p.i. (D) and the infection was measured at 72 h p.i. by focus-forming units FFUs counting (E) (as inhibition percent; mean of three independent experiments; error bars: SD. **p<0.01);
