Figure 3From: Inducible nitric oxide synthase (iNOS) expression in monocytes during acute Dengue Fever in patients and during in vitro infection Confocal microscopy of DENV-Ag expression after in vitro infection of monocyte-rich cultures. Adherent human PBMLs were incubated for three days either with cell culture medium (Figure 3A, 189.5 μm/field), or with infectious DENV (Figure 3B, 125 μm/field). Cells were labelled with antibody to DENV-Ag and anti-mouse IgG-FITC.Back to article page
