prM-AIDs inhibited ADE of DENV infection in vivo. (A) Schematic representation of the study design. Mice were first administered with naive mouse antibodies (NM-Abs), prM mAb and prM-AIDs, then 24 h later they were challenged with DENV-1 by i.p.. Blood was collected from the vail veins from 0 to 5 days post-infection. (B) Viral copies in the blood cells were quantified by qRT-PCR. (C) Infectious viral particles in the plasma were assessed by plaque assay. (D) Platelets in blood were counted using a hemocytometer under a light microscope. (E,F) The levels of ALT and IL-10 in plasma were measured by ELISA at day 3 post-infection. n = 4–5 mice per group. Error bars show the means ± SEM and pairwise comparisons were performed by non-parametric Mann-Whitney test (*p < 0.05).
