Figure 1From: ISG15 facilitates cellular antiviral response to dengue and west nile virus infection in vitroIsg15 is upregulated upon DENV (A) or WNV (B) infection. The virus burdens were analyzed by measuring the virus E gene copy using quantitative RT-PCR, and normalized to mouse beta actin gene. Results are expressed as the mean + the SEM. * p < 0.05 and ** p < 0.01. Representative results from at least 3 independent experiments.Back to article page
