ZIKV replicates and targets neurons in adult human cortical tissue. a Human temporal lobe cortical tissue fragments were sectioned into 400 µm slices and maintained in culture for 4 days prior to incubation with ZIKV (107 PFU) or mock medium for 1 h, followed by washout. Slices were used for immunohistochemistry, and culture medium was collected for determination of virus titers. b Quantitation of infectious viral particles in the culture medium by plaque assay. Bars represent means ± SEM. Symbols represent means of duplicate or triplicate determinations from four independent human donors (shown in different colors) at each time point. (*p = 0.0411, input (4 h after washout) vs 48 or 72 h after washout; Friedman followed by Dunn’s post-test). ck Representative images of double immunofluorescence labeling for ZIKV (NS2B protein, red) and NeuN (green) (ce), GFAP (f–h), or F4/80 (ik) in ZIKV -infected human tissue slices from two independent donors. Scale bar = 50 μm. Source data from panel b are provided as Source Data File
