<p>(A) WT mice (<i>n</i> = 6 mice per group) were inoculated with different inoculums of adapted-DENV-3 (i.p) and lethality was evaluated every 12 hours for 14 days. Results are expressed as % of survival. In Figs (B–L) WT mice (n = 6 per group) were inoculated with 10LD<sub>50</sub> (1000 PFU) of DENV-3 (i.p) and in the third, fifth or in the seventh day of infection mice were culled and blood and tissues were collected for the following analysis: (B) Change in body weight was expressed as percentage of initial weight loss. (C) Mechanical hypernociception was assessed daily. Results are shown as the difference between the force (g) necessary to induce dorsal flexion of tibio-tarsal joint, followed by paw withdraw, before and after DENV-3 inoculation. In (D), hematocrit was expressed as % volume occupied by red blood cells (left panel) and the number of platelets was shown as platelets ×10<sup>3</sup>/µl of blood (right panel). (E) Changes in vascular permeability in the liver and lungs are shown as µg Evans blue per 100 mg of tissue (left and right panels, respectively). (F) Shows changes in Systolic blood pressure from baseline until day 7 after infection expressed as Δ of blood pressure in mmHg. (G) AST (left panel) and ALT (right panel) activity determination in plasma of control and DENV-3-infected mice was shown as U/dL of plasma. (H–L) Concentrations of IL-6, TNF-α, IFN-γ IL-12/23p40 and IL-18, quantified by ELISA. Results are shown as pg per mL (serum) or pg per 100 mg (tissue). All results are expressed as mean ± SEM and are representative of at least two experiments. * for P<0.05 when compared to control uninfected mice. 10 LD<sub>50</sub> corresponds to 1000 PFU of adapted-DENV-3. ND – not detectable. NA – not assessed. NI- Not-infected. dpi – days post-infection.</p
