Fig. 3. Full-length gH/gL elicits higher neutralizing titers than the gH/gL ectodomain when delivered by LION/repRNA.

Fig. 3

a Reciprocal gH/gL endpoint binding titers elicited by LION/repRNA encoding the soluble gH/gL ectodomain measured by ELISA as indicated. Titers elicited by the 10 μg prime-boost regimen with full-length membrane-anchored gH/gL from Fig. 2 are shown for comparison. The sera from (a) was evaluated in neutralization assays carried out in epithelial (b), or B cells (c). Each dot represents the average of three technical replicates for an individual mouse at each timepoint (n = 8 for full-length gH/gL and n = 5 for gH/gL ectodomain) and the lines connect the means. The arrows indicate the time of immunization. Asterisks denote a statistically significant difference between the two groups at a given time point determined using a Mann-Whitney test where * indicates p ≤ 0.05 and ** indicates p ≤ 0.01. dj Pooled immune sera from mice vaccinated with LION/repRNA encoding full-length and gH/gL ectodomain were evaluated for their ability to compete for binding to EBV gH/gL with the indicated mAbs by competitive ELISA. Each dot represents a technical replicate with a line connecting the mean.
