Resistance is specific to GP-mediated infection. Resistant cell lines were challenged with HIV pseudotypes encoding GFP and bearing VSV G, ZEBOV GP, ZEBOV GP′ (a) SEBOV GP, CIEBOV GP, or REBOV GP (b). Percent cells transformed was quantitated by flow cytometry. Bars represent average of means from three or four experiments done in triplicate; error bars represent standard error means. Asterick indicates statistically significant difference in infection level between GP and GP′ (p=0.04).
